Clinical

1) I often have athletes come into the clinic that have been aggressively stretching their hips or shoulders.  They keep getting tight, keep stretching, and keep getting injured.  I have found that the culprit for these injuries is usually not a mobility problem.  Instead, it is often the result of a poorly tied knot.2) Mike Cantrell teaches you about rib cage dynamics in these 2 videos (1, 2).  Great stuff for anyone that enjoys learning about anatomy, biomechanics, and movement.3) Great summary video on prescribing running shoes.4) Are your patients using their Short Head Biceps Femoris to compensate for a lack of hip extension in closed chain movement patterns?  Kathy Dooley thinks so and discusses more clinical pearls in this phenomenal anatomy post.5) Zac Cupples cleans out his nose and moves better - another first-person perspective on the PRI rabbit hole.6) Lance Goyke goes over the non-popular functions of the Serratus Anterior: Rib Cage Retraction, ER Lower Ribs, IR Upper Ribs, Contralateral Translation of the Thorax, Contralateral Thoracic Rotation.7) NOI goes over the importance of the Sural Nerve.  I actually just had a patient this week who thought she had a sprained ankle, but it turned out to be a sural nerve pathology.  Her symptoms were resolved after 1 week.  I created a chart with all the neurodynamic tensioners in this article.8) Great TMD pearl from Erson “They are using their capital extensors, instead of gravity and diagastrics to help open their mouth. We should not have to use capital extensors to promote end range mandible depression. This also leads to overuse of cervical protracted posture, which may place stress on the mandible elevators and TM joint.”9) Michael Mullins shared an interesting story on the teeth-ACL correlation.  Then he provided this article for more information - Teeth as Sensory Organs.  Very interesting stuff - “In this paradigm, tooth contacts are understood to initiate streams of mechanosensory information that shape oromotor behavior.”10) Sometimes tibial IR mobilizations can be too provocative.  Shante Cofield goes over a smart alternative tibial IR mobilization that unloads the joint and gives some indications of which patients will likely benefit from this mob.11) Erson’s 5 Rules for Resets: 1) It has to be Novel 2) Hit the End-Range 3) Frequent Reinforcement 4) No Pain 5) Education

“graded exposure to end range reduces threat associated with movement, also bombards the CNS with novel and non threatening proprioceptive information”

"the nervous system is easily tricked, but not easily convinced"

"education is empowerment"

12) The Nordic Hamstring Exercise for preventing hamstring strains is something you should know about.13) Zac Cupples reviews Interdisciplinary Integration with some great information on the over-achievers, vision, and even the auditory system..14) “Strength training is one of many options to buffer stress.” -Charlie Weingroff with another great share including some gems on fascia15) Andreo Spina goes over 5 Ways to Promote a Healthy Musculoskeletal System in Children: 1) Don’t Rush Walking 2) No Shoes/Socks 3) Pick Stuff Up With Your Feet 4) No Hands When Standing 5) Physical Play16) We’ve been using this approximation and positional release technique in our clinic with some success.  For one patient, the approximation aspect provided >50% improvement in ROM.17) “There is no lymphatic system in the brain, so the brain uses cerebral spinal fluid to clear the toxins that build up in the brain during the day, and yep you guessed it, this process only happens during sleep.” -Paul Lagerman goes over the correlation of Pain and Sleep.  For more articles on sleep, check out the references from this article.18) The Gait Guys, providing some of the best stuff out there:

“What ischial-femoral impingement might look like as aberrant shoe wear.”

Short Foot or the Toe Spread Out Exercise?  Here’s one of the answers.

""The electrical signal that drives a given movement is therefore an amalgam — a summation — of the rhythms of all the motor neurons firing at a given moment.” This is of course monitored (and modified) by one of our best friends, the cerebellum."

Why you shouldn't just be simply activating weak muscles for a movement solution.  "You may be over riding the central pattern generators, reflex responses and complex cortical loops arthrogenic responses, which could be neuro-protectively calculated."

3 categories of muscle weakness "Local causes include muscle injury and muscle pathologies, like muscular dystrophy and neuromuscular endplate disorders like myasthenia gravis. Segmental causes are largely due to reflexes which occur at the spinal cord level. Long loop and cortical causes are due to an increased inhibition or lack of drive from higher centers, such as the motor cortex and cerebellum."

"Remember the foot intrinsics fire from midstance to pre swing, further stabilizing the foot “core”."

Pain & Neuroscience

19) “And without the ability to regulate our basic needs, engagement with the environment thru sensorimotor processing is limited. This is why peripheral vision is decreased during stress (they literally have tunnel vision) and it's probably why movement suffers because if you can't perceive sensations accurately you don't make good motor plans.” -Seth Oberst writes a great piece reviewing the Polyvagal Theory and correlating it with Maslow’s Hierarchy of Needs.  Read it.20) This article covers a ton of neuroscience - top-down & bottom-up influence, expectations, biases, attention, and perception.  Very applicable to what we do in the clinic.  Expectations influence perception.21) Good read from Lorimer Moseley - No Brain, No Pain.  “any credible evidence of danger to your body will make pain worse and any credible evidence of safety to your body will make it better”22) “Animal studies provide convincing evidence that the sympathetic nervous system is involved in certain forms of chronic pain.” -Peter Drummond23) Todd Hargrove goes over Greg Lehman’s course on pain science.  I agree, clinicians should be able to dissociate chronic pain from biomechanics - especially when it comes to communication and education.  But I also want my patients to biomechanically be able to dissociate their hips from their spine.  #Bathwater24) Movement variability has been getting a lot of attention these days.  “If someone does not have a system capable of varying its movement then finding alternative strategies may be problematic and thus possibly lead to chronicity.”

Don’t forget that mobility (degrees of freedom) dictates the amount of available patterns.  This is one of the reasons why 9 year olds have more variability than 70 year olds.

Training

25) I always enjoy feeling awkward when I move.  It’s good for your body and your mind.  Here’s a couple ways to feel awkward in a “Primal Warm-Up” from Andrew Reed.  Give it a try and be the weird guy in the gym.26) GMB teach you how to do a Muscle Up27) YLMSportsScience shares a quick infographic on the Science of Post Activation Potential28) The unstable ones can’t slow down.  “This is also where the pain science and movement science worlds don’t realize they’re often saying the same thing. Asking someone to move differently is training the musculoskeletal and the nervous systems. Changing how you say, move your arm, changing that habit, is training the brain.”-Brian Reddy29) Dean Somerset goes over anterior hip anatomy, Sahrmann’s anterior femoral glide syndrome, and provides a few isolated hip exercises.30) Eric Cressey with solid training advice as always: incorporating single leg pauses, rotational low rows, RTC exercises after overhead work, and different strength qualities.31) “In intermediate and fast fibers mitochondria are developed by pushing the fibers into light acidity (slight local fatigue), then backing off and recovering aerobically over and over.” -An interesting read from Pavel on long rests for capacity, the effects of acidity, and why we should focus on the mitochondria rather than the energy systems.32) Lance Goyke goes over some neuroscience, habits, willpower, diet, and exercise.  A good post to give to your clients to read - How Exercise Helps You Stop Eating Dessert33) CrossFit is always a fun discussion topic on social media (for better or worse).

Stuart McGill had some interesting things to say in this interview - “Olympic lifting must find the lifter. Not the other way around given the special anatomical gifts needed to lift with efficiency and injury resiliency.”

These are two of my more popular articles.  This one elaborates on what McGill discusses in the above article.  This one discusses a common CrossFit mistake that most people miss.

7 Rules for Preventing CrossFit Injuries

34) 4 Unconventional Fat Loss Methods from Mike Robertson: Low Intensity, New HIIT, Focus on Recovery, Front Load Energy System Work.  I like the pyramid in this article.35) “Begin with the end in mind” Mike Reinold goes over periodization.  I first heard about the Undulating Model from Cal Dietz a couple years ago - very interesting stuff.36) Eric Cressey has the best Baseball stuff out there.  If you or your clients have any interest in this sport, read this quick post here.  And here’s another one on some things that should change in the Baseball Culture.37) John O’Neil goes over Motivation, 3 important factors, and makes it clinically applicable:

“Autonomy in the training process is a client’s ownership of their program, understanding that while they are provided structure and coaching, they are the one executing the movements and looking to improve upon their given goals.

Mastery is the ability to perform the process of the given program to the point where variables – movement type, loading scheme, structure – need to be altered periodically to maintain both psychological interest and physiological adaptations.

Purpose is a client’s awareness that movements they are given have reasons in progression towards their goals and the client feeling the need to continue the process to optimize performance.”

38) I recently had a patient that introduced me to Jeff Galloway and his run-walk-run program.  It’s not just for beginners.  It’s for performance.  Very interesting.

Research

39) "A significant association was found between lumbar disc degeneration and tibiotalar joint arthritis (P < .01)."40) “These results provide experimental support for the importance of action exploration, a key idea from reinforcement learning theory, showing that motor variability facilitates motor learning in humans and that our nervous systems actively regulate it to improve learning.”41) “When compared to a matched comparison group, there were impairments of scapular musculature strength and endurance in patients with LE (lateral epicondylitis), suggesting that the scapular musculature should be assessed and potentially treated in this population.”42) “beyond the amplitude of the neural drive, muscle force depends on several biomechanical factors (eg, specific tension and physiological cross-sectional area). Therefore, the VL/VM activation ratio does not provide information about the VL/VM force ratio, which is ultimately the most important information from a clinical perspective.”43) “A program focused on eccentric hamstring strengthening may prevent hamstring injuries.” -SMR’s review of the Nordic Hamstring Exercise44) Chris Beardsley goes over all the Kettlebell Research.  The conclusion is that Kettlebells are awesome and you should use them.45) “Fiber bundle length decreased significantly as a result of a concentric training program, whereas the eccentric strength training did not result in a decreased fiber bundle length. Pennation angle, muscle thickness and muscle strength increased similarly in both groups. Applying eccentric training may lead to preservation of fiber bundle length, allowing the muscle to sustain force over a greater ROM.”46) I’ve always liked this study - “The results indicate that the master cyclists have a significant asymmetry (30 ± 8 to 23 ± 13 %) during the pedaling exercise at all power output level tested in this study (100, 150, 200 and 250 W).”47) “a nostril will drive air to the ipsilateral lung” -Zac Cupples shares this article48) MRI Knuckle Cracking (shared by Jon Herting). Here’s the cavitation article on pubmed.49) “‘The Placebome’; the impact of genetics to the placebo response.  There is evidence for several genetic variations in neurotransmitters and neurological pathways mediating the placebo response, which could possibly explain the variations in clinical outcomes.”50) “The purpose of this review is not to suggest a whole-scale rejection of periodization theories but to promote a refined awareness of their various strengths and weaknesses.” -Important article from John Kiely on Periodization51) Strength wins again!  “Individualised PRT (progressive resistance training) intervention targeting the key muscles of lower limbs is more effective than TBE (therapeutic balance exercise) in improving forward limits of stability among elderly people, aged ≥65 years who are not frail.”52) Difference between genders and ITB “females with ITBS exhibited significantly greater hip external rotation (ER) angles during swing phase (52-54% of gait cycle) when compared to male runners. Male runners with ITBS showed decreased hip adduction angles throughout swing phase as well as greater ankle internal rotation.”53) “The closed chain condition elicited significantly higher infraspinatus activation levels than the open chain condition. The posterior deltoid activation levels on the other hand were significantly decreased when the exercises were performed in a closed chain. Moreover, the infraspinatus:posterior deltoid activation ratio was significantly higher in the closed kinetic chain condition.”54) “Tennis players above 16 years of age had less scapular upward rotation than the younger age groups. “55) Still fascinated by this stuff - Catherine Kerr on the somatosensory attention56) “Study suggests that unloaded movement facilitation is more effective than "no exercise" for chronic lower back pain” (shared by TPI)57) Research and evidence is very important.  But don’t become a Research Snob.

“Another important consideration is the fact that there a significant number of incredibly brilliant minds in the industry, and while there are a lot of them in academia, there are a significant number who are not.” =Mike Mullins

April Hits (2015)

Clinical

1) Lately, I’ve been interested in the connection between vision and the cervical spine.  Here’s two interesting articles I found this month.

“The direction of eye movements was horizontal when the sternocleidomastoidmuscle on one side of the neck and the splenius on the other side were activated, and downward when both splenii muscles were vibrated.”

"During neck rotation SCM and MF EMG was less when the eyes were maintained with a constant intra-orbit position that was opposite to the direction of rotation compared to trials in which the eyes were maintained in the same direction as the head movement."

I put people in challenging developmental positions and have them use their vision to either increase motion or to dissociate their vision from their cervical spine (changing muscle activation patterns).

2) Still don’t think vision and the cervical spine are related?  Check out this research article on vision, cervical rotation, and pain “When vision overstated the amount of rotation, self reported pain occurred at 7% less rotation than under conditions of accurate visual feedback, and when vision understated rotation, pain occurred at 6% greater rotation than under conditions of accurate visual feedback.”3) The sign of a great educator is someone that takes complex ideas and makes them seem simple.  Here’s the Great Cantrell teaching the importance of hamstring flexibility (must watch video - share with your peers)4) I like Kelly Starrett’s concept of the shoulder shelf.5) Here's best 20 second explanation of the ankle as a torque convertor.6) You’ve never head a physical therapist talk about wisdom teeth like this - “the maxillary (top side) wisdom teeth limit the excursion of my lateral pterygoids for lateral trusive movements” -Zac Cupples7) Erson goes over End-Range Loading and 4 reasons why it works.8) Seth O’Neil shares a great article on the soleus and it’s implications on achilles tendonosis.  Some gems:

“The actual forces it produces are around 8 times body weight.(5) In comparison the Gastrocnemius produces forces around 3 times body weight.”

“Gastrocnemius functions largely isometrically whilst the Soleus tends to function eccentrically”

“91% of symptomatic tendons have pathology in the medial part of the tendon- the part relating to Soleus.”

“Most runners with AT will need to use body weight + up to an additional 50-75%. Without this they will not be working at a high enough threshold to rehab to an eccentric strength of around 200% body weight (as shown to be the average for healthy runners).”

9) Here's some PRI magic using occlusion for hip flexor flexibility.  I would love to know what the treatment plan is with this guy.10) “One of the best ways to keep people motivated in activity is to find something that gets them into or close to their flow state where they are engaged.” -Gray Cook on his latest checklist and the Skill:Challenge Ratio11) Only Zac Cupples can make you think about where to sit during the evaluation - “Being to someone’s left could build a better emotional connection.”12) Erson goes over 5 More PT Myths.13) Mike Reinold shows you a simple accessory respiratory muscle assessment (inhale in cervical rotation).14) “Here we show that contrary to predictions from optimal control theory, habitual muscle activation patterns are surprisingly robust to changes in limb biomechanics.”15) Perry Nichelston teaches you some baby moves - unilateral crawl16) “Perhaps we need to think of extension as system closure; a system closing problem. Flexion will be the solution to open the system.” -Zac Cupples17) "Peripheral nerves require extraordinary mobility in relation to surrounding tissues, sometimes sliding up to 2 centimetres as we move." -David Butler18) Mike Reinold goes over some overhead shoulder mobility concepts.  I’ve written detailed articles on two of these concepts (scapula upward rotation & lumbopelvic/core).19) Allan Phillips has a great DNS Review -

“3month position is the “starting line.”  Lift legs off table and secure torso w/o deviation.  Starts with position at ribcage and pelvis.  If not optimal, load shifts to extremities”

“Main time to influence joint morphology is in first year of life”

“Deep neck flexors require stability of abdominal wall”

“Breathing is an expression of the nervous system”

“Abdominal wall contraction can prevent diaphragm from descending”

20) Erson collects advice from Mike Reinold, Barton Bishop, Chris Johnson, Chris Nentarz, and Charlie Weingroff.  Some great gems in there including: “In reality there are flaws in all of the different models of physical therapy. Don't get locked into one thought process or you'll spend more time defending your belief than allowing yourself to grow.”-Reinold |:| “You are only as good as your last injury and the extent to which you rehabbed it”-Johnson |:| “Anything can work for anybody, and nothing works for everybody.”-Weingroff21) Michael Mullins teaches you about Dennison Laterality Repatterning (here & here)22) Navin Hettiarachchi introduced me to this interesting toy for improving foot/ankle function - Cobblestone Mats.23) Kathy Dooley is one of my favorite anatomy teachers.  The “subclavius assists the scapular protraction executed by pectoralis minor and serratus anterior”.  It also has a close proximity to the subclavian vein and artery thus making it relevant for all distal structures via circulation/blood supply.24) Hamstrings

Mike Robertson goes over some injury prevention strategies here.

Harold Gibbons keeps it simple and effective here.

25) In PT school, I remember learning how to teach neck patients to stretch their “levator scapulae”.  In the clinic, I remember these patients coming back feeling much worse without resolving any of their dysfunction.  Cranking and pulling on the cervical spine isn’t a good idea.  A few may get a temporary relief, but this does not provide any permanent change in the tissues.  It doesn’t lengthen the "tight" muscles.  It just places a ton of stress on the delicate cervical spine.  Here is an alternative exercise for neck "tightness" that provides relief without excessive stress.

Clinical Question

26) Two of my clinical mentors are asking a good question regarding post-op knees.  Do femoral nerve blocks affect the patients ability to regain their quad strength after surgery?  Should they only be doing saphenous nerve blocks?  What are the risks and rewards?  If it's just for pain, is it really worth the risk?  Anyone that has any answers or opinions please leave a comment at the bottom of this post.

Pain & Neuroscience

27) Emotions control the volume of pain.  Here’s an article you can share with your patients.28) Radiolab Podcast has a great Placebo Episode.  It's an easy place to start for those that want to learn more about placebo effects and the processing component of the human body.29) Erson’s 5 Pain Science Rants30) Zac Cupples says Salient 21 times and discusses pain - “A salient input is necessary for an altered output.”31) I’ve been studying attention focus recently.  It’s pretty fascinating stuff.  Apparently other people think so too.

Here are 5 questions to ask yourself about attention that can have a profound affect on your happiness.

“Improving one's awareness of the blind spots can improve attentional focus and potentially optimize motor output without inducing a maladaptive response - such as pain, anxiety, excess muscular tension. Because the brain has already "been there" and explored the region, the sensory input (whatever the mode) is likely much less threatening to the system. “ -Seth Oberst with a great read on attentional focus

Chronic pain patients have difficulty switching their attention focus off of their painful body part.  Here's a great TED talk on attention and mindfulness from Catherine Kerr.

Training

32) Here’s a nice collection of some higher level foot stability exercises - I like the kettlebell swap idea.33) I like this idea of the Landmine Squat.  I found it helpful to pre-activate the anterior core.  Give it a try and see what you think for yourself.34) Dean Somerset goes over 5 Squatting Concepts 1) Pause Squats are Underrated 2) Most Squat Restrictions Are Not Muscular 3) Valgus Collapse is Less About Technique & More About Reaction 4) Long Torsos Are Better Than Long Femurs 5) Breathing Patterns Change with Load and Fatigue35) Some interesting PRI Golf exercises - I like the sidelying 45 degree leg lifts.36) Pavel’s 5 Ab Training Mistakes 1) Chasing the Burn 2) Not Focusing on the Contraction 3) Not Using Enough Resistance 4) Exclusively Isometric Training 5) Not Making Every Exercise an Abdominal Exercise37) Feel awkward with GMB.  Here’s their thorough tutorial on How to Planche.38) 5 Miguel Aragoncillo Tips 1) Use Discovery Learning 2) Reduce the Amount of Corrective Exercises 3) Know the Difference Between Blocked & Random Practice 4) Oatmeal 5) Band Love (including this great core engaged hip flexor mob)39) Pavel discusses rest intervals (ordinary, stress, stimulation) - “ if you are only practicing incomplete recovery between your sets of strength exercises, you will never achieve your potential”40) Dean Somerset shares a great modification to the side plank for those with shoulder problems.41) Loaded Carries may be the best abdominal exercise you’re not doing.42) Harold Gibbons shares some breathing based core exercises43) We all benefit when Eric Cressey writes articles to promote a product.  Tons of good stuff from him this month:

He take post-activation potential (PAP) and creates a system (Stage System) to improve your lifting performance.

The Split-Stance Anti-Rotational Ball Scoop Toss exercise.

“The lower the motivation of the exercising individual, the greater the need for randomness to keep exercise engaging. This is working out.  The higher the motivation of the exercising individual, the greater the need for repetition to deliver a specific physiological effect. This is training.” -Eric Cressey on Repetition vs Randomness

15 Random Thoughts on S&C Programs

Slowing down the concentric - “taking 3-5 seconds to externally rotate the humerus during cuff work can prevent the deltoid or lat from taking over” -Eric Cressey

Research

44) This is a dead horse that can’t get beat enough.  “Asymptomatic shoulder abnormalities were found in 96% of the subjects”  Medical imaging is NOT the gold standard for movement, health, or function.45) The latest research in fascia “supports the multiple functions of the connective tissue matrix, combining strength and elasticity – biotensegrity – a word that describes ways in which the architecture of connective tissue cells – such as fibroblasts – respond to different degrees and forms of mechanical load leading to rapid modification of chemical behavior and physiological adaptation – including gene expression and inflammatory responses.”46) Found this entertaining.  Now you can tell your RTC tear patients that it happened because they’re fat!  But really, it has to do with hypovascular zones and cardiorespiratory efficiency.47) The Top 6 Recent Tendinopathy Papers (share with your peers - most people in medicine don’t know this stuff)48) “The infraspinatus muscle was found to be composed of three partitions: a superior, middle and inferior part were present in all muscles. In 62.5% of the muscles, full compartmentalization was established (i.e. a separate nerve branch entered all three partitions). It can be speculated that the different neuromuscular partitions correspond to different biomechanical functions of the infraspinatus.”49) Runners need Achilles Viagra #Stiffness50) Cuing for more knee flexion and less impact on single leg landing led to: increased knee flexion, decreased peak vertical ground reaction forces, and decreased co-contraction (quad & HS).  #ACL51) Chris Beardsley provides a thorough evidence-based review52) Chris Beardsley also has an equally thorough evidence-based review of the Glute Max53) “The study found that twelve weeks of sitting Tai Chi training could improve the dynamic sitting balance and handgrip strength, but not QOL, of the SCI survivors.”54) I heard Gray Cook talking about this years ago - if he was a hipster, he’d be saying he did it before it was researched.  “A simple beam-walking task and an easily collected measure of distance traveled detected differences in walking balance proficiency across sensorimotor abilities.”  #ResearchLagsClinicalExcellence55) “Surgical decompression yielded similar effects to a PT regimen among patients with LSS (lumbar spine stenosis) who were surgical candidates.”  Why choose PT?  One of the side effects of surgery could be death or paralyzation.

1) There’s a weird campaign by some Hipster PTs who are arguing that posture isn’t important.  Maybe they’re doing it for social media popularity.  Maybe what they’re really trying to say is that we shouldn’t create thought viruses.  Maybe what they’re saying is that we shouldn’t blame all of our patients' problems on a static postural assessment.  Maybe they don’t understand that posture is a biobehavioral pattern.  Regardless of their underlying point, dogmatically saying posture doesn’t matter is like saying physics and physiology doesn’t matter.2) “From a sensory perspective, moving fast has a lot of sensory noise - it's loud…By lowering the magnitude of the sensory stimuli, we can better perceive excessive muscular rigidity and help to regulate it.” - Seth Oberst3) “The 90-90 hip lift says that the pelvis is too far forward, especially on the left and we would like to put it back to a neutral position and we are going to use a couple muscles to keep it there” -The Nominalist4) Here’s a list of some DNS based exercises.5) A Therapeutic Alliance as "a trusting connection and rapport established between therapist and client through collaboration, communication, therapist empathy and mutual understanding and respect."  |:| “Quite a bit of literature links a trusting therapeutic relationship to superior patient outcomes”6) The squat is a very trendy social media topic.  Which leads to a ton of people discussing it with a black and white approach.  And someone always has the newest way to squat better or the real reason you can’t squat well.  Tom Purvis goes over the gray of squat biomechanics and body proportions.  One of the best explanations out there.  7) Here's some easy to read pain science analogies and the weighted sleeper exercise for shoulder internal rotation by The Nominalist8) “In most cases, the perception of tightness is just that, only a perception.” -Erson9) “Every exercise is an assessment. Each time your clients and athletes move, they're providing you with information. The more you pay attention, the better you'll be able to individualize their programs and coaching cues moving forward.’ -Eric Cressey goes over 10 assessment tips10) Pelvic floor, breath holding, and crossfit.  “Lifting with a belt also increases the IAP by bracing the back, sides and front of the abdomen…but what about the top (diaphragm) and bottom (pelvic floor) of the abdominal canister? What often happens is that the very strong diaphragm can hold its own and so the pressure gets directed downwards into the pelvic floor.”11) Mike Robertson shares his 3 Safe Shoulder Exercises12) Inside the Mind of Charlie Weingroff (Random Thoughts #2)

• "Screening generally with unlearned movements first will allow for a more organic appraisal of joint position, which is all any movement screen should be judged against."

• "Testing with another series of movements very different from your training but requiring the same “bucket” of movement qualities is likely far more indicative of general motor skill acquisition."

• "One of the summary interpretations that I have made is that for balanced joint position with ideal co-contraction to be achieved, we require full non-threatened joint motion in all planes and vectors."

• "Develop motor skills and fitness simultaneously with carry over to terminal athletic goals"

• "Can you have any kind of legitimate grip without a particular centration of the scapula and t-spine?"

13) “The craniocervical region is incredibly mobile for a reason. That reason is to create precision for our sensors: vision, audition, olfaction, respiration, and vestibular sensation. This precision occurs reflexively, whereas other appendages act proprioceptively.  These sensors drive the neck. Losing the ability to sense is what can increase the need for a neck to become stable. And when you can’t move a stable neck, teeth may be one thing you try to use.” -Zac Cupples with a great article on the cervical spine, occlusion, and the girl he wants to marry14) "When a patient cannot move properly without pain, paraesthesia, or perception of stretch, and a manual technique is performed, we are really modulating that perception." -Erson Religioso15) The Foot Core System - a great read on foot function, evolutionary adaptation, and intrinsic foot assessment & treatment.  An important read for anyone that works with people that have feet.16) Erson shares 2 studies on the importance of vision with cervical patients.17) Louis Gifford’s Mature Organism Model really laid down the blueprint for how I view my patients (inputs, processing, outputs).  Zac Cupples shares his interpretation of this model, jokes about your mom, and lays out a way to influence this system.  A great read that everyone can relate to.18) “When we’re going to move, it’s very biologically important to be engaged in our movement.  If we look at the natural environment around us, animals are 100% engaged in the moment and in their current activity.  When we have two electronic devices on our hip just so we can run—one so we can text and the other so we can listen to music—I’m not sure that many of the lessons that running in the environment could teach us are even accessible.” -Gray Cook19) “What’s the point of asking an athlete to commit an hour a day to more efficient movement if you're not going to address the four hours per day they are reinforcing an unhealthy movement?” -Lee Burton on texting posture20) Erson reviews SFMA 2.  “you can ride a bike after not doing it for 10 years, but can you still do calculus?”21) 7 Reasons to Goblet Squat from the Nominalist 1) Comfortable Hips Below Knees 2) Opens Up Areas that Stretching May Not 3) Increases Hip Capsule ROM 4) Exposes Foot/Ankle Weakness 5) Pelvic Floor Alignment 6) Easy to Reproduce Independently 7) Helps to Isolate the Shoulder22) Shameless Self Promotion - I agree with John, it’s a lot easier to put people in positions where they can’t compensate instead of using 17 different verbal cues.  Sometimes I use the same concept for overhead movements - the deep squat locks out the lumbar spine and prevents a compensatory rib flare.23) It’s important to remember that the human body is an adaptation machine.  If you play basketball 3 times a week, it will adapt to handle those loads (assuming graded exposure).  However, if you only play basketball every several months, the body will not be adapted to handle those loads.  Injury risk and pain are potential outcomes.  Brian Reddy discusses this concept in this article - “Soreness is a sign of working your body in a way it’s not used to.”  Educate your patients.24) Another great post from Zac Cupples.  You might have a different view of the Thomas Test after reading this one.25) Ron Hruska describes my NYC patient population.26) I was having some difficulty determining the driving force of the pes cavus foot type.  Specifically I wasn't confident whether it was a plantarflexex forefoot or a rearfoot varus.  Dr. Suzanne Fuchs pointed me towards the Coleman’s test (5 min into this video).27) Loukia Lili is getting treatment from the cueing master, Mike Cantrell.  Here are 4 videos using PRI and some solid coaching to ensure proper muscle activation (1, 2, 3, 4).28) Dennis Treubig shares 5 things he wishes he would have learned in PT school 1) Treatments aren’t very specific 2) A movement assessment system is important 3) Modern Pain Science 4) How to pick CEU courses 5) Medical imaging is clinically irrelevant 29) One thing I wish we would have learned more about in PT school is psychology.  It’s such an important component that was not covered well in school.30) "attempting to achieve sufficient dorsiflexion through the combined ‘foot pronation-ankle dorsiflexion’ mechanism, as opposed to just dorsiflexion from the ankle mortise joint alone, may change the dynamics of the entire limb…. in this case, hip flexion range observation. Is this because when dorsiflexion is cheated via foot pronation, instead of just ankle dorsiflexion, there is more internal tibia/femoral spin than would normally occur from just sagittal ankle hinging which can in turn impair terminal hip flexion range via impingement type action ? I think so. It would be cool to see what would have happened in the study had the pronating clients been shown my foot tripod restoration exercise.”   -Dr. Allen

Pain

31) “when I can’t find something physically stopping you from doing something, I have to help you get back to normal by using graded exposure (CBT techniques) and explaining pain to you” -Antony Lo31) Kento Kamiyama discusses the lion-pain metaphor.  “The adrenaline rush is a normal response and once the lion goes away, everything returns back to normal.   However, when it is prolonged the body starts using cortisol instead of adrenaline.  Cortisol is a more potent and longer lasting chemical to deal with longer lasting threats.“32) What your adrenal glands really looks like.33) Sometimes new terms are created for self-promotional reasons or for the sake of argument.  Many times I find this trivial - we often waste too much time on semantics.  However, when new terms are created for educational purposes it can be powerful.  NOI recently released a new book to help patients understand pain.  They created the terms DIMs & SIMs (Danger In Me & Safety In Me) - “This is a reminder of the power of context.”34) “Social context matters. It can affect our learning processes, and does so also in the context of pain. While we can only speculate about the underlying mechanisms at this point, it seems plausible that a threatening environment (be it social or not) could facilitate the rapid distinction between threat and safety”-Kai Karos

Inefficient breathing could result in muscular imbalance, motor control alterations, and physiological adaptations that are capable of modifying movement.”47) There’s a lot of great work being done on tendinopathies.  Please share this study with your peers - too many people in the medical field are only using eccentrics.  “There is little clinical or mechanistic evidence for isolating the eccentric component”48) If you only practice evidence-based medicine, you are almost 2 decades behind!  “Studies have shown that it takes an average of about 17 years for new knowledge generated by randomized trials to be incorporated into practice.”49) If you’re into injury prevention, you should also be into fatigue prevention “Following a fatiguing exercise protocol, participants showed increased anterior tibial translation, compressive force, and knee flexion range of motion during the transition from non-weight-bearing to weight-bearing. This illustrates an inability of the lower extremity muscles to stabilize the knee joint.”50) A sensorimotor approach to Chronic Ankle Instability - “The STARS interventions include ankle joint mobilization, plantar massage, and triceps surae strengthening.”51) A great read on proprioception and body awareness.  Tons of great references throughout.52) You can explain this with basic biomechanics, physiology, breathing, DNS or PRI philosophies, or just common sense - standing with excessive lumbar lordosis isn't the best posture for your back.

Ingber

• “There my studies of cell biology and also of sculpture led me to realize that the question of how living things form has less to do with chemical composition than with architecture.  The molecules and cells that form our tissues are continually removed and replaced; it is the maintenance of pattern and architecture, I reasoned, that we call life.”

• “changing cytoskeletal geometry and mechanics could affect biochemical reactions and even alter the genes that are activated and thus the proteins that are made.”

• “At the Johns Hopkins School of Medicine, Donald S. Coffey and Kenneth J. Pienta found that tensegrity structures function as coupled harmonic oscillators. DNA, nuclei, cytoskeletal filaments, membrane ion channels and entire living cells and tissues exhibit characteristic resonant frequencies of vibration. Very simply, transmission of tension through a tensegrity array provides a means to distribute forces to all interconnected elements and, at the same time, to couple, or "tune," the whole system mechanically as one.”

My Secret Acupuncture Experiment

I ran a secret experiment on our acupuncturist, Mila Mintsis.But before I go into the details, it’s important to know a few things about the human body.

4 Facts to Know

1) The nervous system controls the way we move (muscles are just the “puppets”)2) The autonomic nervous system has a huge influence on our movement

• Sympathetic = tightens muscles for fight or flight, can increase pain

• Parasympathetic = relaxes muscles for rest and relax, can decrease pain

3) Sympathetic Activity EXTENDS our body

• Too much sympathetic activity tightens our big muscles (global mobilisers)

• Puts us in a High Threshold Strategy

• This can lead to back pain, tight calfs, hip pain, shoulder pain, neck tightness, etc.

4) A simple an easy test for the nervous system is a toe touch

• If you can’t touch your toes, one of the culprits could be too much sympathetic nervous system activity - thus too much extension and muscle tightness (muscle tone)

My Experiment

I simply assessed the subject's toe touch before and after acupuncture.I didn’t want Mila to know what I was doing.  I wanted her to be “blind” to the experiment.  She could have easily used Acupuncture to loosen specific muscles and increase range of motion.  To get an unbiased result, she couldn’t even know I was doing an experiment.After acupuncture the subject had a dramatic improvement in his toe touch and a significant decrease in his perception of tightness.How did this happen?  Mila didn’t perform acupuncture with the intention of improving his toe touch.  So there is no kinesiological or mechanical explanation.  What it comes down to one of the most beneficial side effects of acupuncture - decreased sympathetic activity and increased parasympathetic activity.  Less stress, more rest (for the brain and body).  Just after one session, the tight extensor muscles were calmed down, the autonomic nervous system was more balance, and his movement significantly improved.

February Hits (2015)

Clinical

1) I first learned about the relationship between the pelvis and hip ROM from Chris Johnson - you can instantly increase hip IR on the table by having the patient posterior pelvic tilt.  Then upon studying the concepts of SFMA, DNS, and PRI, I began to understand how the pelvis (as well as diaphragm/thorax/spine) influences the hips.  Now I understand that most hip impingement patients are really pelvis patients, not femur patients.  Mike Reinold wrote a concise and simple post on this concept here.2) The Gait Guys go over the objective hallux valgus assessment and ways to treat it.3) Here’s a great 3 minute video that goes over both the cause and treatment of tendinopathies.4) There’s a lot of discussion on the thoracic spine, rib kinematics, breathing, and shoulder function.  The Nominalist goes over one of the more important aspects of this kinetic chain - Posterior Expansion.  It’s an important post for all clinicians (PRI inspired, but discussed in a way that everyone can understand it).5) Another great running post by Tom Goom.  This article includes a great graphic on the Foot Strike Continuum and some advice on changing mechanics - “In a nutshell what I’m saying is if you want to change footstrike, make a small, manageable change by adjusting stride frequency and stride length, rather than switching footstrike altogether. Increasing stride frequency by as little as 5-10% can significantly reduce loading while having minimal negative effects on performance.”6) I’m sure Eric Cressey is having a big “I told you so” moment…”In conclusion, shrug exercises at 90° or 150° of shoulder abduction angle could be advocated to activate scapular upward rotators, decrease SDRI, and increase CTA in individuals with scapular downward rotation impairment.”7) The Kitchen Sink - neuro-modulation techniques, compression wrap, corkscrew, pre-activation, synergistic muscles...Erson’s take on the ASLR Fix.8) The Nominalist dissects shoulder traction exercises (hangs, farmer’s walks) and gives you a ton of ways to use them with your patients.9) Here’s a great post by Dave Tilley on alternative reasons for hip flexor “tightness” (Part 1, Part 2, & Part 3). The List - Guarding for Instability, Breathing Dysfunction, Too Much Sympathetic Drive, Dysfunctional Core, Poor Motor Skills, Lifestyle, The Other Planes of Hip Motion10) Erson has an MDT cervical clinical pearl - retraction and sidebending for a quick assessment.11) Congratulations to Zac Cupples on becoming PRC.  He is one of the best resources for PRI information.  His summary on advanced integration including this gem “When exhalation occurs, exoskeletal stability increases and chamber pressure decreases.”12) A clinical example of using MDT both distally and proximally for a chronic ankle sprain.13) Maybe the thoracic smash isn’t the answer to all T-Spine issues.  “So, maybe the ‘stiffness’ we feel, at least in a proportion of our patients, is not truly articular in nature, but rather, a reflection of the increased resting tone and dominance of the global muscles of the thorax (which also connect to the scapula, humerus, lumbopelvis, and neck) that creates neuromyofascial compression of joints of the thorax.” -Linda-Joy Lee14) 8 Reasons Why You Shouldn’t Release the Psoas15) Lance Goyke has a 4 part PRI Advanced Integration series (Part 1, Part 2, Part 3, Part 4)16) 2 Great Quotes from Gray Cook - “If you think about it, the SAID principle (Specific Adaptation to Imposed Demand) can be divided right down the middle with specific adaptation being the role of the organism and imposed demand being the role of the environment.”  |:|  “If you’re disengaged or detached from the activity you’re doing, you cannot get into a flow state.  Flow is where records are broken and the intrinsic value of movement can be realized.”17) Here's my review and interpretation of Andreo Spina's Functional Range Release.  It includes an argument for histology, mechanotransduction, dynamic systems theory, why isometrics are the best, and many clinical pearls from Spina.18) Don’t let the arms internally rotate and adduct during the wall slide - via Eric Cressey19) Dynamic Valgus probably isn’t an adductor problem.  A long, interesting read that breaks down the adductor kinesiology, goes over valgus culprits (excessive tibial ER), has visual examples of common compensations, and explains why you shouldn’t do the split stance adductor mobilization.20) Why only kill 2 birds with 1 stone when you can kill 5?  One of my favorite all encompassing “shoulder” exercise.21) Good review of 5 Aspects of ITB Syndrome- 1) Direct Attachment 2) Indirect Attachment 3) Movement Culprit 4) Femur Centration 5) Morphology22) Ischial-femoral impingement.  Never heard of it?  Me neither.  Read this post by the Gait Guys to immediately improve your assessment.23) Leon Chaitow reminds us of the adverse effects of respiratory alkalosis.24) Kathy Dooley goes over the functional anatomy of the QL.  “It’s tight because you’ve lost spinal stability in flexion. Stretch the QL without providing stability, and it will backfire by making itself even tighter...The opposite is true in extension intolerance. The QL is primarily a tonic back extensor and often a pain generator in those who tend to extend too much through the lumbar spine.”25) 3 ways to get out of high-threshold system from Seth Oberst: 1) Optimize Breathing 2) Balance the ANS 3) Go Slower26) If you’re unfamiliar with the high-threshold concept, check out an article I wrote a few years ago describing the difference between Low and High Threshold Strategies.27) Kegels vs. Squats “Teaching women to consciously integrate the pelvic floor into the squatting action to a depth that they can control their form and not tuck under, will retrain the optimum length and function of both the pelvic floor and glutes. I like to teach women to open and lengthen their pelvic floor with an inhale as they lower into the squat, and exhale with a pelvic floor lift as they rise. To me this is the blend and the best of both worlds.” - Julie Wiebe28) Dana Santas goes over Yoga for Athletes (it’s not about stretching) - “Incorporate core and pelvic floor work to inhibit back extensors.”29) A simple shoulder dissociation assessment and xiphoid cues from the Nominalist.  “ ...‘move the top of your sternum back and up behind your ears‘. The chin tuck move will quickly fade out of your vocabulary...”30) I wish I would have heard this before my first PRI course “If we are hyperinflated in particular areas (think left chest wall), how can we expect to go to the left side? Left space is already filled with air. Airflow must be transferred to the right side in order for us to maximally close down our left. Maximal left sided closure via a zone of apposition is necessary to create true left stance.”-Zac Cupples with another great PRI post - this time on PRI Integration for Baseball31) Erson's 5's

Erson shares his Top 5 Online Resources.  He also gives a shout out to some other blogs as well (thanks Erson!)

Erson shares his 5 Favorite Anke Resets - repeated ankle plantarflexion, repeated hallux flexion, tibial IR mob, repeated tibiotalor lateral glides, sciatic neurodynamics/posterior chain

5 Easy Screens from Erson: 1) Cervical Retraction & Sidebend 2) Terminal Knee Extension 3) Shoulder Extension 4) ASLR/PSLR 5) ½ Kneeling Dorsiflexion

One of my favorite posts of the month - Erson goes over his thoughts on 5 Common Treatments.  A great breakdown of how things really work.  Well worth the read.

Pain

32) “Perhaps, though, this is exactly what we do when we identify hyperalgesia: we assume that we know how much pain the person should be feeling – a questionable assumption in itself.” |:| “At this point we must ask for clarity on the distinction between central sensitisation and a lowered pain threshold to a given stimulus: what is the difference? To me, it seems clear that a lowered pain threshold is a clinical finding, whereas (in Woolf’s view) central sensitisation is one of two mechanisms that could underlie that finding. Peripheral sensitisation is the other option; if that can be ruled out, then the patient’s lowered pain threshold is probably due to central sensitisation.” -Tory Madden33) Another great read from Todd Hargrove - “Dogs will eventually stop drooling if you ring the bell enough times without bringing dinner. And people can hopefully extinguish their association between pain and a movement by finding a way to move without pain.“34) Greg Lehman shares a Pain Science Workbook for patients and therapists - you can download it or send it to patients.

Training

35) The LATD (Long Term Athletic Development) seems like a well articulated program36) Some solid, simple, coaching cues from Eric Cressey37) “In order to master anything, you must study, practice, experiment, and evaluate.” -Greg Robins38) Mike Robertson shares his in-season training pearls.  1) Don’t Make Them Sore 2) Consolidate Stress 3) Keep Everyone Fit39) GMB goes over some exercises for foot motor control, strength, and mobility.40) If you are into human movement, you must know about Pavel Tsatouline.  Learn more about Pavel in this great Tim Ferris Interview.41) 5 DNS Warm-Up Exercises42) “If you’re looking for smashing heavier weights in something like a deadlift or a squat, using a fast, plyometric type jump activity immediately prior may be beneficial. If you’re looking to sprint or produce maximal velocity contractions, using some relatively heavy loading with a focus on the hardest contractions against the load could be beneficial.”  -Dean Somerset43) Another entry point for squatting - “Consider adding the bottom-up approach one leg at a time.”44) “a single bell forces you to constantly work hard to fight rotation and prove you are stable and in control” -Andrew Read 45) Mike Reinold brings up a good point about progressing core training from isometrics (minimal spinal motion) to concentrics/eccentrics (lots of spinal motion).46) What do you think about the “valgus twitch”?  The valgus twitch is transient knee valgus that occurs in advanced lifters during deep squats (see Crossfit Games for a good example).  Bret Contreras goes over this mechanism in this post.47) The Runners 3x3 by Chris Johnson48) A great quick and easy read on energy systems.49) GMB categorizes different types of Body Weight Movement Approaches50) Here’s a great post on building the braking system.  Tons of great progressions for your lower extremity patients/clients.

Research

51) VMO or Hip Strengthening for PFPS?  Bret Contreras writes a great article to display the importance of focusing on the question instead of trying to find articles that support your stance (confirmation bias).  Everyone should take a look at this one.52) A 2 sentence review of the Polyvagal Theory by Jesse Cullen-DuPont - “Brain detecting threat - yes or no. Remaining outputs follow suit.”53) “Deficits in sensory and motor systems present bilaterally in unilateral tendinopathy. This implies potential central nervous system involvement. This indicates that rehabilitation should consider the contralateral side of patients.”54) I’ve had patients come in and claim that Crossfit cured much of their pain.  Here’s a study that might suggest why - “An LMC (low-load motor control) intervention may result in superior outcomes in activity, movement control, and muscle endurance compared to an HLL (high-load lifting) intervention, but not in pain intensity, strength, or endurance.”55) Post-surgical extremity patients should be exercising the non-involved side.  Here’s why.56) “Take Home Message: There are many clinical special tests geared towards diagnosing labral tears and femoroacetabular impingement.  Unfortunately, these tests are largely not helpful in confirming the presence of the pathology in population that is likely to have either.”57) Strength wins again.  “weaker athletes displayed more asymmetry than stronger athletes”58) An interesting read on DOMS and what really helps (Yoga and Whiskey) - “Lactate and muscle soreness are not related.” -Jules Mitchell59) “Thus, the 4-week 15:15 MVO2 kettlebell protocol, using high intensity kettlebell snatches, significantly improved aerobic capacity in female intercollegiate soccer players and could be used as an alternative mode to maintain or improve cardiovascular conditioning.”60) Research subjects suppress immune responses using physical conditioning.  “You can’t understand immunity without understanding its neural regulation” -Kevin Tracey61) "New research into the way in which we learn new skills finds that a single skill can be learned faster if its follow-through motion is consistent, but multiple skills can be learned simultaneously if the follow-through motion is varied.  “Since we have shown that learning occurs faster with consistent movements, it may therefore be important to consider methods to reduce this variability in order to improve the speed of rehabilitation,” -Dr. Ian Howard

62) “During hopping or jumping muscle fibres contract almost isometrically, while the fascial elements lengthen and shorten like elastic yoyo springs.” -Leon Chaitow63) The ultimate collection of articles, videos, and blogs for Pelvic Floor Anatomy.64) “Epigenetics and deep homology are two sides of the evolutionary coin. Epigenetics helps explain rapid evolutionary changes and highlights the role environments can play in genetic health. Deep homology reminds us of our ancient origins and the glacial pace at which much evolutionary change occurs.” -Zoobiquity65) The Evolution of the Gluteus Maximus by Eirik Garnas.

Andreo Spina's Functional Range Release

I was lucky enough to be invited to another one of Dan Park’s quality continuing education classes at Perfect Stride.  This time it was for Functional Range Release (Upper Extremity) with Andreo Spina.  I had been reading a lot about Spina’s work and was excited at the chance to learn about the FR/FRC techniques and principles.

Andreo Spina

Andreo Spina is the creator of FR (Functional Range Release) and FRC (Functional Range Conditioning).  He is an intelligent, articulate, and opinionated speaker.  He has a great knowledge base and a fresh perspective on the human body.  I’ve taken many continuing education courses over the years; Dr. Spina definitely set the record for most rants.  However, all of his rants have a point and are very educational.  He uses sound logic, conventional wisdom, literature, and dry humor to discuss current practices and clinical beliefs.I walked away from his course with a new perspective on the human body, knowledge of how to influence tissue at the histological level, and became a much more efficient manual therapist.*This is my interpretation of the class and how I conceptualize the approach.  For a more complete understanding I recommend taking one of Dr. Spina's course.  He provides an extensive amount of information and resources (9 on-line learning modules, quality lectures, lifetime membership, and social media support).

Bringing it Back to Histology

Neuo-based approaches have really boomed over the past decade.  And for a good reason - they improve clinical care.  While I love these neurological approaches and understand their value, I also think we can go off the deep end with it.  Sometimes it’s easy to forget there’s a physical human body with constantly adapting tissues.  Just as the nervous system has an influence on tissues, the tissues have an influence on the nervous system.  Even renowned neuroplasticty lover, Lorimer Moseley, has mentioned that we should be considering the role of Bioplasticity.Andreo Spina has done a tremendous job of expanding on this tissue concept and making histology clinically relevant.  FR/FRC focuses on addressing the human body from controlled and specific inputs to influence the histological processes and subsequently, the entire human body.To understand this concept, it is important to recognize that the body is constantly turning over at a cellular level (watch this - tissue remodeling).  I think the quote from the class was “if you look at a picture of yourself from 10 years ago, there won’t be one cell that is the same”.How these cells turnover and in what manner depends on many variables.  Specific to Spina’s work, one of these variables is force.  The force that these tissues “feel” dictates how they turnover.  Force influences cellular activity (fibroblast).  And direction is one of the most important variables of this force.This is a very detailed and scientific rabbit hole to go down.  It involves the piezoelectric effect, tensegrity, mechanotransduction, solid-state biochemistry, collagen, fibroblast activity, cellular signaling, etc.  While it's beyond the scope of this review to discuss these concepts in detail, I'll try to briefly summarize them since it is essential to understanding the FR/FRC system.The influence of force on cellular activity deals with the connections between collagen and cells.  Force is applied to the body and imparted on collagen.  Collagen connects to a cell via integrins.  Different cells grab onto the same collagen fibers (via integrins).  When collagen gets a directional force input, it transmits this signal to multiple cells (tensegrity).  This force is then transmitted from the cell cytoplasm to the nucleus (DNA/RNA).  FORCE IS THE LANGUAGE OF CELLS.  One example of this is Wolff's Law.To put it in clinical terms, your sedentary 45 year old patient that has been wearing high heels for over 30 years is going to have some adaptive tissue changes.  There’s going to be a histological tissue adaptation.  After years of not using ankle dorsiflexion, her body will remove the cells that foster normal dorsiflexion.  There isn’t a neurological trick you can do to change tissue in one session.  In fact, there isn’t any one input that will change tissue immediately.  To adapt and influence that tissue, you will need frequent, long duration, directional force inputs.

What Are We Really Feeling?

Another main concept of the course was to question our manual assessment/intervention.I think an analogy might help explain this concept.Lets take a single-leg stance assessment.  You notice that there’s a significant compensated trendelenburg.  A decade ago we may have accused a weak glute medius and then just hammered the patient with isolated hip abduction exercises (movement blunder).  But now we know there are so many possible causes of this movement pattern that it is nearly impossible to pin it on one thing.The same thing applies for manual therapy.  All we have is our hand contacting another person’s body.  There’s just a hand to skin interface and we are trying to feel for something.  But can we really say what that is?  Is it a fat pocket, malaligned collagen, a tissue anomaly, a genetic difference, or tone?  By saying it’s scar tissue or a knot are we bringing the movement blunder to manual therapy?Adreo Spina thinks so.

• “It is not logical to think that a practitioner can feel 'scar' tissue or 'adhesions.' At the level of 'micro-scarring' in connective tissue, the target is much too small for human touch. Not to mention the abundance of overlying tissue making it impossible to feel alterations in collagen directionality. Our hands can however feel forces. It is the forces generated by movement, or tension, that we attempt to feel. We can also think of it as feeling resistance to passive movement in a particular direction. We feel for aberrant tension…and we treat aberrant tension.”

By focusing on feeling for aberrant forces with movement, we have a more honest assessment.  It takes out the assumption blunder and reduces confirmation biases.

Assessment / Approach

For me, Dr.Spina’s approach is best understood from the Dynamic Systems Theory and Degrees of Freedom Problem point of view.  The premise is that there is an infinite amount of ways for the human body to move.  This is because there is a collective Degrees of Freedom that incorporates ALL the complex variables/sub-systems (in the continually changing internal & external environment) required to achieve a task.  One of these variables/systems is the state of the body’s peripheral tissues.  More specifically, an important tissue variable is the degrees of freedom of the joints (articular ROM).  If there are adaptive histological tissue changes that prevent normal joint movement, then the collective Degrees of Freedom will decrease.  The brain will have less motor control options.  The body will lose movement variability.  The attractor state will deepen.Losing degrees of freedom at the joint level can have a significant impact in the body's ability to manage movement.For an example, lets look at a simple digit lock.  It is not a complex open loop system (actually the opposite), but it'll hopefully help explain how this concept pertains to FR/FRC.Take a 3-digit-lock.  Each digit requires a specific number to match the right combination to unlock the lock.  With the numbers 0-9 and a 3 digit combination, there are 1,000 possible combinations.  If you add just one more digit and make it a 4-digit-lock, the number of possible combinations goes from 1,000 to 10,000.  Pretty significant, right?  Simply adding just 1 digit has a massive effect on the amount of variable combinations.One variable can significantly affect the whole system.You could look at the body the same way.  Having minimal joint motion may provide for some adequate movement options (3-digit-lock).  But having even just a little more joint motion can have significant impact in the movement options (4-digit-lock).  What if you needed the 1,001 movement combination to safely land from a jump?  If you only have 1,000 options, you'll compensate and risk injury.  This analogy works for the entire spectrum, from your 1-digit-lock medicare patients to your 100-digit-lock gymnast.

• Articular DOF = Nervous System DOF = Movement DOF

This is why Andreo Spina’s assessment approach is to first check every articulation of the body (joint ROM).  His philosophy is that if you don't have the prerequisite articular motion then your movement will suffer.  Why not focus on the other variables?  Because you can't build strength, stability, or motor control in ranges you don't have.  Developing the optimal ROM takes priority over developing strength in an inadequate range.Once he assesses the joint articulations, he will assess the soft tissue with palpation and passive movement.  If the person is in pain, he tries to reproduce it with palpation to determine a specific tissue diagnosis.  If there is no pain, he palpates the local area to asses how well the tissues are moving.* (=) is influence

Don’t Hang Up

Force is the input that tells the fibroblasts how to lay down.  Research has shown that it takes 2 minutes for these fibroblasts to become activated.  If you’re constantly changing direction or moving, then the cells won’t get the right input.So if you’re trying to influence tissue, you need to hold the directional force for 2 minutes.  He had a great analogy of a phone call.  You need to stay on the line long enough to get the message across.  If you keep hanging up (e.g. pin and stretch manual techniques, STM, etc.), then the communication won’t go through to the fibroblasts.Keep patients in the same posture, don’t pump through ranges of motion, hold tension longer, think directionally.

Isometrics

Isometrics are extremely beneficial.  Here's a list of 10 reasons why:

1. Gives directional force input (communication)
2. No joint shearing
3. No inflammatory reaction
4. Teaches body how to develop tension in a muscle (motor unit recruitment)
5. Increases strength
6. Least provocative strengthening modality
7. Patients can do it frequently
8. Backs up / covers manual therapy intervention
9. Resets the muscle spindle
10. Safe mechanotransduction

Spina has created a very user friendly system for applying isometrics to influence tissue and improve range of motion.  These are PAILs and RAILs (Progressive Angular Isometric Loading & Regressive Angular Isomeric Loading).  These are very direction specific interventions.  These techniques are best understood in the context of the class, but I will briefly describe them here.PAILs I (Communication)

Guiding Soft Tissue Remoulding/Healing

Does not intend on expanding range

Low level, frequent contractions

PAILs II (Expand Range of Motion)

2 minute passive, direction specific stretch

Followed by ramped isometric contraction in opposite direction (20-30 seconds)

PAILs III & RAILs (Expand ROM & Training Stimulus)

2 minute passive, direciton specific stretch

Ramped isometric contraction with 100% effort (longer duration)

Followed by RAILs (inner range hold, actively pulling deeper into the stretch)

Followed by another deep, passive stretch (and repeat)

Anatomy Pearls

During the palpation aspect of the course, Dr. Spina revealed this disconnect between what we were taught and what is actually in the body.  Here's some of these revelations.

• Levator Scapula is medial on the neck

• The "Levator Scapula TrP" that everyone has is really just where the rhomboid and erector spinae cross

• That thing you poke on the front of people’s shoulder is not the biceps tendon, it’s usually the anterior deltoid

• Teres major/minor and long head triceps is a commonly gunked up area

• The subscapularis tendon becomes transverse humeral ligament

• The long head of the triceps becomes the inferior labrum

• Deep muscle grow off bones (like chia pets) - Examples - quadriceps, brachialis, subscapularis, flexor digitorum profundus

• The pec minor, upper trapezius, and latissimus dorsi are disappointing muscles - thinner than you would think

Randoms

1) We all come from one cell - every cell has the ability to be every other cell2) Pain is a terrible outcome measure (Touch Induced Analgesia)3) Epimysial Groove is an important area to treat4) Mechanical Tension = specific aberrant force, Neurological Tension = can be felt during static palpation and is felt throughout the whole muscle (video demonstration)5) “We’re trying to palpate the forces that are restricting movements”6) In the fascia superfiscialis there are small pockets of adipose tissue - this might be the grittiness you feel with IASTM7) BioFlow - continuum of tissues - it all blends together - tissue types are just a different expression of connective tissue8) Fibroblasts - undifferentiated connective tissue cell that can become a precursor cell for many different types of connective tissue (tendons, bone, cartilage, muscle, etc.)9) It doesn’t matter which type of tissue, the response to load/signal will be similar10) “Never use a cannon to kill a fly” -Confusious11) Van Der Wal (article, video)12) No passive structures, just structures whose tension is tuned by the muscles (active structures)13) Force to one cell will cause a cascade of signaling throughout many different cells14) For plastic changes you need >2 minutes (induce thrixotropy and piezoelectric)15) Injury = Fibrosis = Friction/Loss Of Relative Tissue Motion16) After injury - the body recalibrates the stretch reflex threshold = faster activation of muscle spindles during movement = reflexive contraction, prematurely17) Don’t bring a mechanical intervention to a neurologic problem18) The more the neural drive, the less the access to the connective tissue for manual treatment19) Without direction, fibroblasts smear collagen all over the place and create fibrosis20) Deep tissues are mostly proprioceptive/afferent structures (when these are dysfunctional, superficial tissues have high tone)21) Adjust for skin slack or everything will feel like tension22) No single input causes permanent changes - “we’re not fixing anything”23) “I can’t rub someone flexible”24) Flexibility is governed by the nervous system.  You have to train it in the gym, not manually fix it with your hands.25) Inputs

• Muscle responds to NS quickly

• Connective Tissue responds to longer force inputs

26) 1st Job of Rehab = Guide the way the tissue is healing - tell the fibroblasts where to lay down collagen27) Rehab in the injured posture to repair/strengthen damaged tissues28) "Any fool can make something complicated. It takes a genius to make it simple." -Woody Guthrie

• Load > Capacity = Injury

• Load < Capacity = Rehab

• Capacity >> Load = Prevention

29) The deeper in the body, the more the connective tissue (pedunculation)30) Muscles can contract in various ways - Different fibers pull in different directions - Attachments don’t dictate all movement31) “Create the joint…THEN control the joint…THEN strengthen the joint - this concept is central to the FR and FRC systems.”32) “If you can control the scapula in space, does it matter if it’s winging?”33) Improving skin slide, especially over bony prominences, makes a big difference34) “You’re not palpating muscles, you’re palpating the connective tissues that makes muscles”35) NS only gives you access to the ROM it knows it can control36) “Adding passive mobility is where people get hurt”37) Osteoarthritic Rant

• Age doesn’t decrease flexibility, lack of movement decreases flexibility

• Joints maintain their health with movement

• If your joints moved everyday, an osteophyte can’t develop

• OA occurs from lack of motion

38) “RTC should be called the compressor cuff”39) The best way to assess joint motion is with axial rotation40) Opening vs. Closing restriction

• Opening is normal, tissues have to adapt

• Closing is not - comes from a decentrated joint, or tight opposite joint

41) The more contact you have with the patient, the better you can assess (close the circuit)42) Cyriax Knowledge - The longer a muscle is at contraction, the more the load goes to the tendon43) “Think of the body as one group of CT and proteins are added where movement needs to occur”44) One of my favorite quotes from the course

• “Changing posture is about habitual cueing”

45) Tensegrity model runs through the entire body, from DNA/RNA nucleus to ECM46) Give the cue “hold strong” (good psychological priming)47) “You don’t do PAILs for a muscle, you do it for a direction”48) Check the hands in elbow patients - It’s like the plantar fascia in achilles patients49) “Articular independence first….articular interdependence second”

Bottom Line

Overall this was one of my favorite courses I've ever taken.  It gave me a new lens on the human body, provided a simple and effective way to influence tissue, reduced my need for manual therapy, and gave me a direct treatment approach to achieve long term goals.  I highly recommend this course (or the FRC) for all movement professionals.One of the greatest things about Dr. Spina's work is that it can easily be incorporated into any approach.  You can still do all the neurological stuff, but after you get them FN/Centrated/Neutral/Whatever, just add in some inputs that will influence the tissues in the new and improved position.  It's important to work with the nervous system after an injury (motor patterns, pain, ANS, neutrality, etc.), but it's also just as important to work on the tissues themselves.  We are lucky to have so many approaches out there that identify the neurological needs of the system.  Now we're lucky to have Dr. Spina's approach to address the histological needs of the system.

Dig Deeper

Cellular/Histological/Bioflow

This is a big rabbit hole to go down.  There is plethora of research and articles.  It is difficult to just reference one.  FR/FRC Instructor, Michael Chivers, recommends starting with Helen Langevin and Donald Ingber.

Motor Control/Dynamic Systems

This is similar to researching cellular adaptations and histological changes to input.  There is so much out there that it becomes difficult to reference.  If you are new to these concepts, start by researching the different types of motor control theories.  Then research Bernstein's work and the degrees of freedom problem.  Then dive into the Dynamic Systems Theory.

My favorite article in this field is from Esther Helen and Linda Smith (Thelen, E. and Smith, L. B. 2007. Dynamic Systems Theories. Handbook of Child Psychology. I:6)

Fascia/Tensegrity

This has become a standard in the movement sciences (or at least I hope so).  Most clinicians are familiar with this approach thanks to the work of Tom Myers, Robert Schleip, Jaap Van Der Wal, and Leon Chaitow (among many others).

January Hits (2015)

1) If you are a manual therapist, please understand the current concepts of manual therapy.  One of these concepts is that we cannot cause an immediate and permanent plastic deformation of tissues.  So painfully digging into tissues to "release" them is really just another form of torture.  Here are 3 Pain Free Manual Techniques from Erson - Pec Minor, Psoas, QL.2) “Based on animal studies, it has been proposed that central sensitization associated to nociception (maladaptive plasticity) and plasticity related to the sensorimotor learning (adaptive plasticity) share similar neural mechanisms and compete with each other.”3) Seth Oberst has a great read on hyperinflation and what to do about it (Part 1, Part 2).4) The FIFA 11+ seems like a good program to reduce injuries.5) Here's some advice for getting stronger.  I particularly like the Russian Skill-Strength methodology of the “everyday maximum”.6) We’re lucky Charlie Weingroff does brain unloading like this.  Tons of great stuff.  “Treat tissues compressing an artery if there is pain.  If it works, it was claudication, not mechanical or neuromuscular. - “So if we have a very low lactic threshold by being terribly unfit and more activity or sooner during any given activity throws us to the lactic energy systems, we are more apt to developing to resting muscle tension and if continued chronic TrP. - “Research is history.” - “Passive stretching without developing tension throughout the range is a mistake. - ”Stress can only do 4 things: Change pain, Change mobility, Change Motor Performance, Change Fitness"7) Attrition substitution is a type of availability heuristic that occurs often in this field.  Make sure you're aware of it so that you don't make this common clinical mistake.8) “Ankle sprain is associated with altered global motor strategy as well as localized joint impairment”-Jordana Bieze Foster (@biezefoster)9) Good vibrations - Make your stressed out, over sympathetic patients hum.  Humming stimulates the vagus nerve.10) The environment I create to stop low kettlebell swings.11) “Much like life, movement is a balance of moderation, modulation and modification.” -Michael Mullins has a great post on knee pain12) Another Chubbs study - “Early rapid strength production of the hip extensor muscles may be a sensitive and effective measure for discriminating between elderly females of different fall histories.”13) Anatomy geeks should love this.14) Another great functional anatomy post from Kathy Dooley - The Psoas - “If the hips are tight from a forward pelvic tilt, psoas is not the one to stretch. Imagine putting nerve tension on all those structures passing through psoas!  Stabilize the spine and move through the hip.  Free up the ribcage so the diaphragm can properly move.  Lay off psoas and focus on adjacent anatomy.”15) Once again, medical imaging may be leading us to the wrong conclusions.  “The 95% reference intervals of morphometric measurements of FAI in asymptomatic hips were beyond the abnormal thresholds, which was especially true for cam-type FAI.” 16) Gait Guys always have good stuff.  Here's a good read on why metatarsalgia happens.  Here's a foot waving exercise for metatarsal plantarflexion and intrinsic dissociation (Part 1, Part 2). 17) The Nominalist is on a tear this month.  Here's a bunch of great articles with a solid perspective on clinical intervention.

Don’t forget about the rotational component of ankle dorsiflexion

"Watch for the unilateral side-benders, they’re everywhere.”

The Myth of the Hinging Knee

Eclectic approach to hip mobility

Foot-to-Hip, PRI, Toe Spaces, Avoiding the Forefoot, and CKC Hamstring

”Shoulders are rarely shoulders, and even if they are shoulders, they’re also necks, and rib cages and cores. “

18) “The goal is to optimize the efficiency of the body so that the environment you create causes appropriate adaptation with minimal compensation.” -Gray Cook discusses Russian/Hardstyle/Strongfirst Swing vs. American/Overhead/Crossfit Swing19) Adriaan Louw thinks there are two main questions we should ask patients to understand their beliefs:

1. “What do you think is going on with your _______ (fill in the painful area)?”

2. "What do you think should be done for your _______ (fill in the body part/issue)?"

“Nothing is as powerful as changing someone’s beliefs.”

20) Dean Summerset goes over 5 Mobility tips - 1) Use Breathing 2) Add Stability 3) Get the Feet Right/Bottom-Up Approach 4) Get the Head Right/Top-Down Approach 5) Distal Fascial Lines 21) Erson - 5 Mistakes you might be making22) Research is confirming what many of us already know - Core Stability Training and the ACL .  "Conclusion: Better H/Q strength ratio was seen in core stabilization group. Core stabilization exercises improved postural stability more than classic rehabilitation."23) “High heeled shoe research model suggests increasing height by 13 cm shortens gastroc by 5%, leads to sarcomere loss.”-Jordana Bieze Foster (@biezefoster)24) Charlie Weingroff shares 8 Reasons Why The Knee Buckles (at the bottom of the post)25) A review of Erson’s Eclectic Approach Course26) “Protect before correct” -Gray Cook27) We already know this clinically, but it’s nice to have some research to back it up.  “These findings suggest that alignment of the lower extremity up to the pelvic girdle, can be altered, due to forces acting on the foot.”  28) Zac Cupples makes you think about wisdom teeth and depth perception.  "My wisdom teeth essentially alter pterygoid position and reduce my mandible’s capacity to move."29) Two great things in one post - beer and periodization.  A great read that simplifies the periodization process.
