Clinical

1) Dan Pope shares another awesome video exercise progression - this time it’s on jump variations.  He literally shows you how to bridge the gap in this one.  Great stuff.2) Leon Chaitow goes over pulsed muscle energy technique.  A much safer and more effective intervention than cranking on joints with aggressive stretching.  Take note of his communication in the video - calm, slow, speaking - external cues - takes his time to get the patient to perform exactly what he wants.  #Variables3) Tom Goom writes some of the best running articles out there.  Here’s a great post on the importance of load capacity, the envelope of function, kinetic chain load, and the non-tissue issues.  This might be the most important concept in rehab.4) Here’s a nice shoulder exercise - Horizontal Abduction with Press.  This can also be used to improve rotation.5) Visual cues may be the easiest way to immediately correct faulty movement patterns.6) Zac Cupples reminds you about the ZOA and teaches some good subscap stuff in this I&I review.7) Read this great review of static foot posture and arch height correlations.  Even if you don’t like the foot, reading this will give you a great biomechanical thought experiment and strengthen your movement knowledge.

Sure, you don’t want to make too many assumptions when assessing static foot postures, but “low-arched runners exhibited more knee, soft tissue, and medial injuries (e.g., adductor strain, medial knee and ankle injury, and sesamoid/first metatarsophalangeal joint injury), while high-arched runners had a greater prevalence of bony injuries (e.g., stress fractures) and lateral injuries (e.g., greater trochanter bursitis, iliotibial band friction syndrome, and/or lateral ankle sprains).”

“During midstance, because the adducted talus is held in a fixed position by superimposed body weight, the external rotation moment created by the swing limb is unable to generate a force strong enough to abduct the talus. As a result, the torsional forces associated with this external rotation moment must be temporarily stored in the stance limb. The release of these stored torsional forces is occasionally evidenced by a sudden “abductory twist” of the rearfoot as heel lift occurs; i.e., because ground reaction forces no longer maintain the plantar heel, the entire rearfoot is free to snap medially, as though released from a loaded spring.” 

8) Here’s one reason why your jaw may be a compensator “your body loaded the TMJ with the most amount of proprioception per surface area of any other moveable joint.”.9) A good read from Charlie Weingroff on the difference between a warm up and corrective exercises. Hint: they are not analogous.10) “Consider someone who has a femoral retroversion will likely have a bone to bone contact sooner in a flexion range of motion compared to someone who has more of an anteversion alignment, and if that difference is 20 degrees or more, that could be the difference between squatting above parallel and sitting your hamstring comfortably on your calves.” -Dean Somerset with an awesome article on hip morphology.  Seriously, read this one.11) The eyes are window to the soul, the nails are a window to foot biomechanics?  Interesting post from the Gait Guys on how pincer nails develop - ““the pincer nail group had significantly lower pressure on the first toe than the control group. In both the barefoot and shod state, the peak pressure area was mostly the metatarsal head area in the pincer nail group, whereas it was mostly the first toe area in the control group.”12) “I don’t believe breathing drills will cure everything.  However, I do believe that utilizing good breathing mechanics along with other intervention is an essential part of optimal function mentally and physically.“ -Kento Kamiyama13) While I think muscle slings are fairly limiting and over-simplified terms for clinicians, they’re great for patient communication.  Here’s a nice easy article with some great graphics on the “muscle slings”14) Very interesting TED talk from Peter Lovatt on dance, thinking, and hormones.  He has another TED talk on psychology and dance.  Thanks for the share Suzanne Fuchs.15) Erson shares some useful wrist directional preference cases.  16) “So it is good to remember that our capacity to think and feel is supported in large part by the neural hardware and software that creates our ability to move and perceive. By developing one we develop the other. It’s all connected of course.” -Great post by Todd Hargrove with quotes on the importance of movement

Pain & Neuroscience

• "One of my biggest clinical mistakes is forgetting graded exposure rules apply to explaining pain" -Zac Cupples

17) An rare, honest article on explaining pain18) Intrinsic focus improves tactile sensation in new study. For more information on this concept and how it relates to movement science read this article (int cue art).19) “Be suspicious of any statement that says a brain area is a center responsible for some function. The notion of functions being products of brain areas or centers is left over from the days when most evidence about brain function was based on the effects of brain lesions localized to specific areas.  Today, we think of functions as products of systems rather than of areas. Neurons in areas contribute because they are part of a system. The amygdala, for example, contributes to threat detection because it is part of a threat detection system.  And just because the amygdala contributes to threat detection does not mean that threat detection is the only function to which it contributes. Amygdala neurons, for example, are also components of systems that process the significance of stimuli related to eating, drinking, sex, and addictive drugs.” -Joseph E LeDoux Ph.D.20) Pain is always a translation.  21) Pain is also a verb.22) An interesting way to use imagery to work with a patient with a thought virus.23) Well this is disappointing..."Of 100 studies published in top-ranking journals in 2008, 75% of social psychology experiments and half of cognitive studies failed the replication test". Another reminder that research isn't always the gold standard. Difference between evidence based practice and research based practice is huge.

Training

24) Michael Mullins shares a great warm-up routine that focuses on “centering, grounding, alternating and reciprocal, and proprioceptive integration.”25) “The vertical tibia requirement is an intention and not a “reality” for many people. The ability to keep the shins vertical (another way of saying vertical tibia) is highly dependent on structure, and an individual should not give up the stability of their spine in order to achieve the intended “vertical shin”.” -Bret Jones on the perfect swing and a great car analogy for individual structure #Variables26) Energy production is pretty important - Joel Jameison on Energy Systems27) Work Capacity is the buzz word, but really it’s just conditioning.  Here’s a great article from Joel Jameison on Conditioning.  It goes over all the important concepts.28) “When I think aerobic training, I think recovery, energy development, and fatigue buffer.” -Lance Goyke29) Probably the best hip mobility drill out there by Andreo Spina30) Great cues from Dean Somerset | Rows - “keep your head behind your chest”  Squat - “aim your butt to your heels”31) "So this is another piece of evidence that one of the benefits of hard training is that you learn to tolerate more pain”32) Look at #1 from Bret Contreras - anatomy is not a death sentence.  Scoliosis, Lamar Grant, and monster deadlifts.33) “With overhead athletes, stick with the overhand grip on the dominant side during alternate grip movements.”-Eric Cressey34) One of the better “__ Steps to Improve ___” I’ve read in a while.  Read this by Alexandre 'Alexey' Senart if you want to improve your pistol squat or coach it better.  “The idea behind this first tip is to prevent our internal “alarm” from going off by taking away half of our bodyweight—source of “danger”—and by maintaining the closest control over our position all the while.”35) Interesting visual cue to improve the squat - “Think of your femurs as being on sliders rather than being hinged on a single pivot point. The intent is to think that they can be shifted away from the pelvis, “making space for the hips” on these imaginary sliders.”  Make sure to watch the video for a better understanding.36) Here’s a nice easy read on the vagus nerve and yoga.37) Research based deep squat defense by Felix Sempf38) Here’s an advanced supine trunk rotation exercise from Brian Schiff.  If this is too difficult or if you patient has pain with rotation, then try this regression.

Exercise of the Month

Contralateral Cross-Crawl Creep

https://www.youtube.com/watch?v=eKr334-7L0AThis had strange origins.  Some believed that you could reverse brain damage, developmental delays, autism, and other neurocognitive problems just by correcting the “missed” stage.  This theory has been disproven and most in the field do not consider it a valid approach.  That said, we don’t need to partake in the common social media act of throwing the baby out with the bathwater.  Cross-crawl patterns and the neurodevelopmental postures are still very useful.  Good movement is good for the brain.  Especially for brains that have dysfunctional movement.When people have dysfunctional movement in the standing posture, one way to reduce the difficulty is to decrease the load on the body and the demands on the brain.  An easy way to accomplish this is to move them down to the ground.  Feldenkrais has been doing this for decades.The contralateral cross-crawl creep not only takes people to the ground, but it does so in a very sensory rich fashion.  It provides a ton of feedback (tactile, visual, vestibular, proprioceptive).  In the prone position the body (and the brain) has to do a lot less work - it doesn’t have to manage as many kinetic forces, there’s not as many degrees of freedom in the system, the center of gravity is much lower, the base of support is much larger, force is distributed across a greater area - and because of this, it’s a safer position.  Plus, there's no need to progress the body forward - even less variables.  It’s basically free movement.Flip Flops Promote

Over Stressed (loss of attention and mindfulness)

Begin with simple “chunking” exercises.  Then perform the full movement together.  Then progress towards full, rhythmic, reciprocal movement with no pause between movements.Look at the hand, go slow, be mindful, feel the movement.Common Problem: surface friction - it may help to place towels or slide pads underneath the knee and/or hand.  Too much friction can turn this nice low-threshold exercise into an uncomfortable, high-threshold, grind.--For more information on the brain, movement, and development I highly recommend looking into Dynamic Systems Theory and Sensory Integration concepts.Special thanks to Perry Nickelston for introducing me to this exercise and to Shante Cofield for hooking me up with this article that goes over some of the concepts discussed above.

Research

39) “Well, there you have it. The “E” in EBP doesn’t translate efficiently into the clinic, will not protect you in lawsuits, and has it’s own inherent (even worse, hidden) biases. On top of that, it could make you delusionally overconfident, despite at least 50% of it being false.”-Cinema Air40) Research shows that sleeping on your side improves waste removal from the brain.41) You know what they say...when you assume...“Our findings suggest that the FPI (foot posture index) may not be an accurate representation of rearfoot or midfoot movement during walking regardless of the measurement technique employed.”42) “Peak knee flexion moment and flexion moment impulse during the second half of stance are related to the progression of PFJ OA “  Correct the variables that affect early knee flexion, then correct the gait pattern.  43) “Although the Thessaly and deep squat tests have a moderate level of reliability, neither test is sufficiently accurate to help in the diagnosis of meniscal tears in primary care. Future research should focus on other relevant patient variables instead of on physical examination tests in the detection of meniscal tears.”  I guess primary care will have to focus on more than just pathoanatomy...44) Great interview with Kathleen Cullen.  Worth a read.  

Here’s one of the best explanations of movement variability I’ve heard - “You probably don't think about it that often but even if you're working on a tennis serve and you feel you've got the movement down perfectly, your muscles are still changing. They’re fatiguing. You have to be updating your motor commands constantly in order to deal with the fact that your motor system is dynamic and changing over time. Put another way, because the  biomechanical properties of the motor system constantly change over time we need to keep it calibrated.”

“The sensory prediction error is the difference between the sensory inflow your brain is expecting if you generate a movement vs. the actual sensory inflow it pulls in.“  #MotorStates

45) “With increased physical development improved messages flow to the brain from all the senses.“-Great article from The Learning Connections Program (thanks Shante)

Other Good Stuff

46) There’s not a ton of this out there in the social media world unfortunately - “positive emotions broaden the scopes of attention and cognition, and, by consequence, initiate upward spirals toward increasing emotional well-being” #StopBeingSoNegative47) “A confident and positive mindset can be both the cause of your actions and the result of them.” -James Clear48) “Socratic questioning helps patients examine the validity of their negative thoughts and gain a broader, more realistic perspective.” #Communication49) Trouble sleeping?  Try Sleep Restriction Therapy.  Great concept that makes a lot of sense.50) “Asking people to eat less, he says, is like asking them to breathe less. It sounds reasonable, so long as you don’t expect them to keep it up for long….Much of the obesity research for the past century has focused on elucidating behavioral techniques that could induce the obese to eat less, tolerate hunger better, and so, by this logic, lose weight. The obesity epidemic suggests that it has failed.” -Gary Taubes51) Here’s how to build mental toughness from Eric Barker52) James Clear goes over what’s overrated and underrated in life.  Some great points in this article.53) Mind-Gut Connection - Higher Anxiety Risk for People with IBD - Another reason for the importance of diet?54) Great video on the science of persuasion #Communication

Instagram

My good friend and outstanding PT, Shante Cofield, has introduced me into the world of Instagram.  It's taken me longer than it should to understand it, but I've really come to enjoy it.  The focus is on quick visual content, so there's much less trolling, negativity, and emotional nonsense than twitter and facebook.  Plus, some people share some beautiful movement, great exercises, and novel interventions.  I don't have much of those on my account, but if you'd like to see pictures of my awesome dog, Rigby, and a couple exercises, then you can follow me here.Here are a few of my favorites from this past month:

Coaching & Cueing (Part 5 - Visual Cues)

Since our species is vision dependent ( >50% of cortex dedicated to processing visual information), visual cues can be an easy way to invoke a sensory change that alters movement patterns.  This includes not only the sensory input from our external environment, but also our unique ability to create an internal vision (motor imagery).

Visual Cueing

External Visual Cue

An external visual cue is simply a change in the environment that the person can see.  The lines on a road are a simple example of this.  The visual input of the lines creates  “barriers” that we have to keep our car between.  It creates an external reference point in the environment to assist with choosing the correct motor output (driving in a straight line).Of course, these visual cues must be used in conjunction with an external verbal cue.  Driving would be pretty dangerous if people didn’t understand that external verbal cue of “stay between the lines when driving”.Specifically with movement training, this type of visual cue can quickly change a movement pattern faster and more efficiently than most other types of cuing.There are two main ways to visually change external environments.  

1. Create a Barrier
2. Create a Target

In the deadlift example I often will place a rolling stool in front of the patients knees, give them the simple external cue of “don’t touch the stool”, and watch them hip hinge cleanly.But you can just as easily perform the same movement with a target cue.  Stand up a foam roller behind them and have them try to hit their butt with it (see picture below).  Butt target practice for proper hinging.  Avoiding or reaching for an object usually creates a better movement pattern than an internal cue of “flexing your arm outward” or “push your knee out” (examples: shoulder - knee).  It avoids clogging up the processing system and allows the brain to figure out the most efficient way to accomplish the task.  It prevents the biggest mistake - the user error.

Can't get your hip patients to stop passively leaning into their labrum and hinging at their backs? Try the visual external cue of a half foam roller. #coach #Cueing #hip #constrainedactionhypothesis #movebetter

A video posted by Aaron Swanson (@aswansonpt) on Sep 1, 2015 at 6:00pm PDT

The examples could go on forever.  Since the visual environment is an open system, there is an infinite amount of ways to alter the environment to change movement patterns.  Creativity is the only limiting factor here.

Internal Visual Cue - Motor Imagery

Motor imagery can be defined as:

• “an active cognitive process during which the representation of a specific action is internally reproduced in working memory without any overt motor output ”-Decety & Grezes, 1999

In other words, it’s giving yourself an internal cue without performing the movement.  The simple act of thinking about internal movement activates some of the same neurons that would fire if you actually physically performed the movement.It stimulates the “top-down” part of movement.  And we know that the cortex is an important variable when it comes to strength.  So think of motor imagery as reps for your brain.This may be the most underutilized coaching and cues in the movement field.  Reading some of the research on this makes me wonder why this isn’t a common thing.  We are missing out on a ton of potential benefits.There’s a decent amount of research out on this, however, most of it has been through the lens of neurological rehab or disuse from immobilization.  But why not use this to help everyone move better? The basic study is this:

• They put two groups in restrictive wrist-hand casts to induce atrophy.  One group performed only motor imagery of the involved immobilised muscles.  The other group did nothing.  The outcomes: the motor imagery group had 50% less strength loss.  They essentially strengthened the muscle without using the muscle.

 Strengthening the body without using the body?  Pretty profound stuff.

Vision

Changing someone’s vision can have profound changed on movement.  As a species we are very dependent on our vision and our culture increases this dependency everyday.  The easiest way to affect vision is to have the patient close their eyes or to alter fixation, which will have a significant effect on their sensory information.  Another way is to cue directional eye movements to change muscle activation and/or challenge stability.  The latest vision sensory change trend seems to be with external devices.  This can be as expensive as strobe glasses or as cheap as smearing vaseline on swimming goggles.However, vision can get much more complicated.  Working with a dysfunctional visual system can give poor information to the system and influence movement negatively.  This is where optometry can have a huge effect on the way people move.  This is it’s own deep rabbit hole to jump down.  The people at PRI have done a tremendous job at bringing this to light and are a great resource for more information.

Summary

Vision may be the easiest way to change sensory information to augment movement.  It can be as easy providing a mirror or as complicated as detailed motor imagery.  Which one you choose depends on you and your client’s goals and your patient population.

August Hits (2015)

Clinical

1) Read this one - the most detailed and thorough blog post on movement variability.  Great stuff from Dave Tilley.

"With movement practice, it is believed by some that coordinative variability decreases (better able to synergies motor patterns for general movement planning) while elemental variability increases (more strategies to generate real time adjustments or handle different conditions while still successfully completing the given task or skill)."

"It also has been suggested that there is an optimal amount of variability for skills. Too little variability in their skill, and the person is stuck with an inflexible system that has very limited adaptability. Too much variability (especially coordinative) in their skill and the person may be all over the place unable to narrow in on the important performance components that lead to skill success."

2) “Mini-strokes affect up to half of the population over forty, but usually go unnoticed until damage builds.”3) Erson has had a busy month as always.  He goes over directional preference and why it's a novel stimulus to the nervous system, provides a quick presentation on the true effects of Spinal Manipulation, goes over 5 tips to improve compliance.   This is a nice explanation of MDT/McKenzie Cervical interventions.  And I like the idea of palpating a tender point and immediately assessing the effects of breathing - Erson’s 5 Breathing Tips.4) “A forefoot varus differs from forefoot supinatus in that a forefoot varus is a congenital osseous deformity that induces subtalar joint pronation, whereas forefoot supinatus is acquired and develops because of subtalar joint pronation.”-Gait Guys5) Zac Cupples shares his opinion on manual therapy.  He makes some great points - everything works, patient preference is paramount, and use it with an assessment technique.6) Very thorough and interesting series on the big toe (mechanics, part 1, 2, 3).  

Hallux DF = Roll, Slide, Compression

7) It’s important to keep in mind that there is no “magical linchpin” in the human body.  Most foot patients aren’t able to progress through their big toe.  And there are a ton of reasons why (rearfoot position, midfoot mobility, forefoot position, pathomechanics, morphology, motor patterns, proximal influence, habit, shoewear, ankle rocker, etc.).  Be thorough.  Use a scalpel instead of a shotgun.8) Quadratus Plantae muscle testing by the Gait Guys9) “The problem with conditioned patterns lies in the inability to get out of them when the task/environment requires it.” -Seth Oberst with another great post.  At the very least, spend some time studying this picture.10) Don’t be afraid of the placebo effect.  Making someone feel better is not a bad thing (as long as you have a plan of care to treat the cause as well).11) “a fatigued muscle decreases the body’s ability to attenuate shock from running” | “The results suggested that the lower extremity is able to adapt to fatigue though altering kinematics at impact and redistributing work to larger proximal muscles.”12) The best training modality may be The Floor

“the floor acts as a mirror to help us complete our self-image"

“It's harder to sit still for long periods of time when seated on the floor, and that's a good thing. Sitting on the floor makes it necessary to squirm and adjust position periodically to stay comfortable. It helps develop a better kinesthetic awareness that leads to a more dynamic posture.”

13) “Our real problem here is when we simply discuss tightness or weakness of a muscle, we can go down the rabbit hole thinking it’s a muscle problem. Very often, it’s a command problem.” -Gray Cook elaborates on his movement theory - sometimes mobility problems are really motor control problems14) Erson displays what Gray goes over in #13 with this motor control fix to a “mobility” problem.15) How do you know when to bring a motor control fix to a mobility problem?

Internal Awareness

I have an interesting patient population.  Most of them are very type A, very stressed out, over educated, sedentary, workaholic New Yorkers.  The normal interventions that work so well with athletes are usually less effective with these stressed out patients.  Below are two articles that discuss an approach I tend to use with these patients.  It's not a strict theory or set of rules, it's simply just a different way to apply what you already do.16) Sure, external cues are better for performance, but what about all the other variables?  We need to stop the tunnel vision and consider internal cues as an important part of improving movement.17) Sometimes the best way to change the processing is from within - here’s how mindfulness/body scan can be used to decrease stress and improve sensory processing.

Calf Strength

Not everyone can resolve all their impairments and move perfectly.  Sometimes compensations are necessary.  One important compensation is plantarflexion strength (especially in older patients).18) “Of particular importance were the compensatory mechanisms provided by the plantar flexors, which were shown to be able to compensate for many musculoskeletal deficits, including diminished muscle strength in the hip and knee flexors and extensors and increased hip joint stiffness. This importance was further highlighted when a normal walking pattern could not be achieved through compensatory action of other muscle groups when the uniarticular and biarticular plantar flexor strength was decreased as a group.”19) “From these results we can conclude that the most important muscle groups compensating for reduced strength in knee and hip muscles are the ankle plantarflexors, hip rotators and hip abductors.”20) “These findings indicate that aging is associated with reduced plantarflexion strength of the toes”21) “When the walking cycle is accompanied by weight bearing, plantar flexion produces a greater blood velocity.”22) It’s not just dorsiflexion ROM - “The strength of the plantar flexors and amount of dorsiflexion excursion were identified as significant predictors of an Achilles tendon overuse injury.”23) Supination = Plantarflexion + Adduction + Inversion

Pain & Neuroscience

24) The importance of building a curriculum to educate your patients - great read from David Butler.  “As with any educational intervention, we should have a curriculum, based on what we determine the key educational performance indicators (KEPIs) are, i.e. the bits of knowledge they really need to “get”.”25) Exercise is medicine.  “Certain types of exercise, namely aerobic, are thought to counteract these age-related drops in BDNF and can restore young levels of BDNF in the aging brain.”26) The Cerebellum

“Although the cerebellum is only 10 percent of the entire brain, it contains more than half of all of the neurons in the brain.”

“Tennis legend Arthur Ashe said famously, "There is a syndrome in sports called 'paralysis by analysis.'" In my opinion, when the cerebrum is overthinking, and the cerebellum is disengaged, "flow" is inhibited and an athlete chokes. I believe this new research confirms that the cerebellum may be at the heart of breaking the vicious cycle of paralysis by analysis by 'unclamping' the cerebrum from overthinking during sports.”

“In order to learn a new motor skill, the researchers found that the cerebellum makes an estimate of the expected sensory inflow that it should get from your sensory system. Then, the cerebellum automatically uses this prediction to compute the difference between what you intended to do and what you actually did. This cerebellar process is key to creating flow and achieving what I call "superfluidity" both on and off the court.”

“Through practice and repetition, the cerebellum also gets better at predicting the unexpected and making lightning fast corrections and readjustments necessary for peak performance.”

27) “Taken together, these findings suggests that at some point in our evolutionary history, we evolved an additional attention network—perhaps in order to better process the world around us,” -Dr. Patel.28) Maybe have them try writing about their pain?  “Some researchers believe that by writing and then editing our own stories, we can change our perceptions of ourselves and identify obstacles that stand in the way of better health.”29) Erson goes over pain science and education.  Regarding discs - make it as easy as simple math “"flexion = +1, extension = -1" keep the equation balanced”.  And here's some great examples of how to educate patients on pain and imaging.30) “As great as a threat pain can be, outputs such as fear, thirst, and hunger will usually trump pain. These outputs occur in response to threats greater than potential tissue damage. Comparing pain to these outputs can be enlightening for patients.” -Zac Cupples reviews Moseley’s pain course.  Great broken bone example/logic in this post.31) ALPIM Syndrome #Variables

A = Anxiety disorder (mostly panic disorder)

L = Ligamentous laxity (joint hypermobility syndrome, scoliosis, double-jointedness, mitral valve prolapse, easy bruising)

P = Pain (fibromyalgia, migraine and chronic daily headache, irritable bowel syndrome, prostatitis/cystitis)

I = Immune disorders (hypothyroidism, asthma, nasal allergies, chronic fatigue syndrome)

M = Mood disorders (major depression, Bipolar II and Bipolar III disorder, tachyphylaxis. Two thirds of patients in the study with mood disorder had diagnosable bipolar disorder and most of those patients had lost response to antidepressants)

32) 10 Research backed Mind-Body Connections.  It always goes back to the Mature Organism Model - inputs influence the processing which influences the output which influences the inputs which influences the...33) Have you considered their vision?  “Vision is typically the predominant sensory system used for guiding locomotion.”34) To be a good physical therapist you must have a solid knowledge of anatomy, physiology, and biomechanics as well as a deep understanding of pain and neuroscience.  However, the most important part of being a good healthcare provider is understanding the person in front of you.  This is often the missing piece when exercise, manual therapy, and education fail to make people feel better.  Read this classic article on the complexity of chronic illness and how it leads to suffering - Loss of self: a fundamental form of suffering in the chronically ill - Charmaz K

“A narrow medicalized view of suffering, solely defined as physical discomfort, ignores or minimizes the broader significance of the suffering experienced by debilitated chronically ill adults.”

“As a result of their illnesses, these individuals suffer from (1) leading restricted lives, (2) experiencing social isolation, (3) being discredited and (4) burdening others. Each of these four scores of suffering is analysed in relation to its effects on the consciousness of the ill person.”

44) “The lunge, dead lift, and kettle swings were low intensity (<50% MVIC) and all showed higher EMG activity for semitendinosus than for biceps femoris. Bridge was low but approaching medium intensity, and the TRX, hamstring bridge, and hamstring curl were all medium intensity exercises (≥50% or <80% MVIC). The Nordic, fitball, and slide leg exercises were all high intensity exercises. Only the fitball exercise showed higher EMG activity in the biceps femoris compared with the semitendinosus. Only lunge and kettle swings showed peak EMG in the muscle-tendon unit lengthening phase and both these exercises involved faster speed.”45) “Some research on why some people don’t respond to exercise “In the following review I will discuss new developments linking genetic and transcript abundance variability to an individual's potential to improve their aerobic capacity or endurance performance or induce muscle hypertrophy.“46) It’s all in the hips.  “The presence of LBP correlated with higher BMI, gluteus medius weakness, low back tenderness, and a positive Trendelenburg sign, particularly on the affected side for those with unilateral LBP.”47) One of the oldest movement modalities should be considered more often - “The research described here demonstrates dance’s ability to penetrate one of the most challenging human conditions: the gradual degeneration of the ability to move.”

Problem & Solution

Our brain is quite complicated.  It is constantly going through extremely complex processing to achieve many different outputs (movement, speech, vision, thoughts, emotion, pain, allostasis, etc.).STRESS is one of the most influential factors on our brain's ability to process efficiently.  And in today's society everyone has had it, many people live in it, and some people can never escape it.Stress an epidemic and it will likely get worse with time.

• “Stress-related ailments cost the United States an estimated $300 billion per year in medical bills and lost productivity, and our usage of sedative drugs has shot off the charts: between 1997 and 2004, Americans more than doubled their yearly spending on antianxiety medications like Xanax and Valium, from $900 million to $2.1 billion. And as the psychologist and anxiety specialist Robert Leahy has pointed out, the seeds of modern worry get planted early. “The average high school kid today has the same level of anxiety as the average psychiatric patient in the early 1950s,” he writes. Security and modernity haven’t brought us calm; they’ve somehow put us out of touch with how to handle our fears” | Excerpt From: Clark, Taylor. “Nerve.”

Fortunately, this situation can be improved with mindfulness.But first, it is important to understand why stress is a problem for the brain.

The Problem = Stress

Arnsten, Amy F. T. "Stress Signalling Pathways That Impair Prefrontal Cortex Structure and Function." Nature Reviews Neuroscience Nat Rev Neurosci 10.6 (2009): 410-22

• “Stress impairs higher-order PFC (Prefrontal Cortex) abilities such as working memory and attention regulation.  Thus, attention regulation switches from thoughtful ‘top-down’ control by the PFC that is based on what is most relevant to the task at hand to ‘bottom-up’ control by the sensory cortices, whereby the salience of the stimulus (for example, whether it is brightly coloured, loud or moving) captures our attention.”

Stress clogs up the brain's processing ability.  It creates excessive noise (e.g. increased alpha power) and disrupts the system's ability to process normal sensory information (among other things). 

The Solution = Mindfulness

Kerr, Catherine E., Matthew D. Sacchet, Sara W. Lazaret al. "Mindfulness Starts with the Body: Somatosensory Attention and Top-down Modulation of Cortical Alpha Rhythms in Mindfulness Meditation." Front. Hum. Neurosci. Frontiers in Human Neuroscience 7 (2013)

• “Higher-order cognitive processes including selective attention and working memory are enabled by the basic ability to filter irrelevant sensory information while focusing on relevant information”
• “Localized attention to body sensations enables subsequent gains in emotional and cognitive regulation by enhancing sensory information processing in the brain”

Mindfulness practice of specific internal sensations (e.g. body scan) helps to modulate the noise in the system (improved alpha power regulation) and promotes improved sensory information processing. 

An Analogy - Your Brain as a Concert

Let's consider the brain as the concert venue and the people as the different parts of the brain.When you have stress the concert venue (brain) becomes a loud rock show in a small club.  You can't really hear anything else that's going on (increased alpha power).  You can't communicate with anyone without shouting (why you only feel pain and discomfort when you're stressed).  You can barely move.  People keep bumping through because they "know someone up front" (poor attention).  That guy that's crowd surfing kicks you in the head.  Someone spills their drink down your back.  You can't see the stage because some idiot in front of you is trying to film it with his iPhone.  And it's just a matter of time before someone starts to yell out something no one wants to hear - "freebird!".Needless to say, this is not the best environment for communicating and organizing plans.In contrast, when you focus on the present sensations within your body the concert venue (brain) becomes a calm symphony concert at an outdoor amphitheater.  Everyone has space.  It's not too loud, you can have a conversation with the person next to you (decreased alpha power).  You can easily walk over to the other side of the venue (attention regulation).  You can not only the stage, but the rest of the venue as well.  And no one is shouting anything you don't want to hear.Don't get me wrong, I love going to rock shows just as much as anyone else.It's important to make sure the noise comes from the Marshall Stacks and not from inside your head.

Conclusion

Unfortunately telling people to quit their jobs, stop paying their mortgage, and hire a nanny are not realistic.  Some people will not be able to modify their lifestyle and will continue to have high stress levels.So what do you do about this?The same thing you would do for someone that has a structural dysfunction that you can't change.  You give them an exercise to help strengthen the system and improve resilience.For these overly stressed individuals this can be anything from a simple body scan meditation to an hour long Qi-Gong class.  It doesn't have to turn them into a vegan hippie, it just has to bring their attention focus to their body.  It has to bring them back to their internal sensations.

Coaching & Cueing (Part 4 - Internal Verbal Cues)

Unfortunately, the rise in popularity of external cueing has led to a bad stigma of internal cueing.  After reading the last article in this series you may be thinking why would you ever internally cue someone?Here’s why:

Benefits of Internal Cues

• Improved Mapping / Body Awareness
• Creates Reference Points
• Teaching Technique/Form
• Muscle Activation - Increased EMG
• Alter Synergistic Muscle Activation
• Mindfulness

3 Topics in This Article

1. Why internal cueing is important
2. The concepts/science behind internal cueing and body awareness
3. Elaboration of the benefits

Disclaimer

Unfortunately, the concepts behind internal cueing aren’t quite as simple as those of external cueing.  Many of these concepts (attention, perception, neuroplasticity, mindfulness, interoception, neuroscience, embodiment, etc.) could each be an article series on their own.  I’ll try to summarize them within the context of internal verbal cueing for movement, but it may be worthwhile to dig deeper in order to better understand these concepts.

Why Internal Cueing is Important

It’s Not Always About Motor Learning or Performance

One of the major concepts that is often overlooked is the fact that most of the research and arguments for external cueing has been done through the lens of motor learning and performance.  But what about all the other variables that we work on with our patients?If you remember from Part I, not everyone is trying to PR their deadlift or improve their free throw percentage.  And not everyone has a history of athletic movement and weight lifting.  There are beginners out there that have no idea what their body is doing when they try to accomplish a physical task.  There are people who haven’t tried a new movement in decades.  There are people who only think externally all day.  There are people who have simply lost their body awareness.So why would you use the same cue for someone who is trying to max out their deadlift that you would for someone who can’t even intrinsically feel their pelvis position on the table?

Why is Body Awareness Important

To reiterate, with internal cueing we’re not talking about performance or even motor learning.  We’re talking about body awareness and control.  You can only control what you can feel.  And if you can’t intrinsically feel a part of your body, that’s a problem.If this were any other sensory input this wouldn’t even be a question.Imagine you are a piano teacher.  You are teaching your student the notes of the C scale. If you started playing the notes on a piano one by one, and your student couldn’t hear anything when you hit the E note, you would consider that a big problem.  If you went to a museum and could see everything but the color orange, you would consider it a big problem.  If you went out to a restaurant...you get the point.  So why do we give our bodies a free pass and just move on despite the fact that we may be missing an essential sensory component?For some patients, intrinsic cueing is a prerequisite for more complex motor tasks and external cueing.  It’s like understanding the notes on the piano before you try to learn classical music.

Semantics - Body Awareness

In the spirit of simplification, I am going to use the term body awareness to express the concept of feeling your body and the associated internal forces.  It’s your brain’s ability to “feel” the internal sensory input.However, it is important to keep in mind that just because we are simplifying this concept for the sake of the topic, it does not mean it is a simple concept.

• “Body awareness is hypothesized as the product of an interactive and dynamic, emergent process that a) reflects complex afferent, efferent, forward and back-projecting neural activities, b) includes cognitive appraisal and unconscious gating, and c) is shaped by the person's attitudes, beliefs, experience and learning in a social and cultural context.”-Wolf Mehling

Since most people don’t even see the top of the internal cueing iceberg, arguing about what’s at the bottom is beyond the scope of this article.

Body Awareness Concepts

Attention for Wiring

• “Remember that it's an attention economy in the brain: where we put our focus determines the wiring that we create.” — David Rock

There is an overwhelming amount of input that is flooding the brain at every moment (visual, auditory, internal processing, viscera, proprioceptive, smell, mechanoreceptors, thoughts, beliefs, etc.).  To avoid going into a seizure, we filter much of this information in order to achieve our “normal” state of being.  One of the things we use to modulate this information is our attention focus.Body awareness is essentially the attention focus of internal sensory information.  This attention focus allows us to “feel” our bodies.Right now there is a plethora of internal sensory information that is ignored so that you can use your attention to read this article.  But if you bring your focus towards feeling your hands you will all of a sudden become “aware” of them. Your hands have not changed, but your attention focus has, which has subsequently changed your brain.This isn’t just a fleeting perceptual change.  It’s a change in the neural connections of your brain.Just like muscles, each time you activate a neural wiring it demands blood flow and nutrients.  This promotes growth and adaptation.  So activating specific neural connections through internal sensory attention focus will “strengthen” one’s body awareness.  It will build the central synaptic body awareness.But it’s not just the “strength” of these neural connections that matters.  The more important part is what these connections represent.

Homunculizing

By paying attention to internal sensory information, your brain can map a better homunculus.  This improved representation gives the brain a better reference point from which it can select the optimal motor strategy for a task.This concept has been discussed over the years as Cortical Smudging.Without an attention focus of a bottom-up feedback, a  pre-selected top-down pattern could be negatively affected.  When top-down references are “off” it causes dysfunctional bottom-up feedback.  When this happens we usually see pain and poor movement.An example of this concept is learning braille.  If you just run your fingers over the bumps without paying attention to what you’re feeling, you’ll never learn.  You need the internal cue to “feel” the bottom-up sensory information so that your brain can start to map out the necessary reference points.  An external cue of push into the paper would not help you read braille.

• “Directing attention to sensory stimulation can increase perceptual sensitivity and modulate neuronal activity” -Heidi Johansen-Berg

Mindfulness

Essentially, internal cues help to improve body awareness through mindfulness.  Research shows mindfulness is  successful for treating various dysfunctions, including stress related responses (anxiety, depression, chronic pain, etc.).We know that stress increases the “noise” in the brain and makes it more difficult to hear other stimuli (i.e. your body).  We see this in the clinic when our patients are struggling to perform a simple exercise despite all the external cues.So how do you quiet the “noise” so that the patient can somatically listen to themselves?Research has shown that paying attention to internal body sensations can help to modulate the alpha rhythms of the brain can quiet the “noise”, thus making it easier to feel internal sensations.Practicing mindfulness with internal cues is like taking them from a rock concert in a small club to an outdoor symphony.

Benefits of Internal Cueing

Internal Cues Provide the Map

One of the factors that influences how we move now is our history (immediately and long term).  And this is where internal cueing can be useful.Take the deadlift for an example.  If someone has had back pain, sits for the majority of their day, hasn’t paid attention or felt their glutes in years, and barely works out, then they will not have their hips mapped out very well in their brains.  They won’t have the body awareness to know the difference between their hips moving and their lumbar spine moving.  Often in the clinic you see these people perform a bridge with an excessive amount of lumbar extension tone.  You ask them where they feel it, and they say their back.  Should you be progressing this person to a deadlift with external cues?Without a proper body map, the motor output will be compromised.  The feedback hasn’t been wired properly, so the feedforward output won’t have a strong reference point.  It’s as if the body will bypass the poorly mapped area (hips) and rely on other areas that are more robustly mapped (back)This is why I think internal cues to improve body awareness are important.  You have to make sure people can intrinsically feel and control their body - which would represent adequate cortical mapping.Once they have this body map awareness, you can confidently progress them to more complex motor tasks and use external cues to achieve the desired output.

• Internal cues provide the map, external cues give you the directions

Changes Focus / Distraction from Pain

Another benefit that I’ve seen clinically from internal cueing is the simple distraction it provides patients.  Often times people will obsess about their pain and it becomes a part of every movement.  Instead of feeling the rest of their body, they focus on the painful area with all of their attention.  Thus, the brain writes more painful wiring for that area.  It’s a vicious cycle.Current research supports this empirical evidence - people in chronic pain have difficulty shifting their attention away from the painful area.Having people focus on internal cues away from the painful site can not only distract them from pain, but it will help the brain wire pain-free movement connections.  And more pain-free movement connections is a great thing for anyone in pain.https://www.youtube.com/watch?v=AGnGRgyLwMs

It Worked for Arnold and the Brosephs

7 time Mr. Olympia, Arnold Schwarzenegger, has discussed his use of internal cues and motor imagery to increase local hypertrophy.  And I think we can all agree that he’s been fairly successful when it comes to local hypertrophy.Ask any bro at the gym what they’re focusing on and the answer will likely be the local muscles.  But don’t judge them, if they’re just trying to increase local hypertrophy then they’re doing the right thing.  We now know that internal cues aren’t great for complex movements due to co-contraction and the constrained hypothesis theory, but they do lead to increased EMG activity.

Ways to Influence the Internal Map

Internal verbal cues may be enough to help change your patient's internal map.  But when this fails, there are many other options to help facilitate the brain change and improve body awareness.

• Attention Focus Internal Cues
• Body Scan / Mindfulness
• Exercise Modification (isolated, slow, groundwork, load, etc.)
• Manual Therapy / Acupuncture
• Dissociation Exercises
• Stretching (Dynamic & Static)
• Somatics (Qi Gong, Alexander Technique, Feldenkrais, Yoga, etc.)

Summary

If you’re working in high level athletics with people who need to improve performance, then external cues are preferred.  However, if you’re working with a much wider population that includes non-athletic people, people in pain, or people that live too externally, then internal cues may be very useful in improving movement and/or pain.  If you are unsure if this type of cueing is needed, simply ask your patient during an exercise - “where do you feel this?”.[subscribe2]

If the neck flexors are inhibited the nervous system senses threat and instability, so on the way down to touch the toes it stiffens the hamstrings so you don’t fall forward hurting yourself.” -Perry Nickelston with an interesting article on the nervous system’s influence on mobility9) Here’s my layman’s article on how to "fix your back" and improve your toe touch in less than 5 minutes.  Sorry for the click-baiting title - it’s really on how to decrease sympathetic tone, initiate non-threatening lumbar flexion, and activate the anterior core with the diaphragm in the proper position.10) Solid review from Zac Cupples on Dry Needling -

“Endogenous opioids play a huge role here. When this system kicks in, there is decreased immune molecule activity, reduced intracellular sodium, and increased potassium. This change increases resting membrane potential from -70 mV to -150 mV. That change makes it pretty tough for nociceptors to produce action potentials."

"Everyone loves the nervous system, but some aneural cells also stimulate opioid production. Both keratinocytes and fibroblasts have been shown to produce opioids, which may be why many skin-level therapies are effective for pain.”

Intrinsic Motivation

11) “Providing athletes with, choice, a rationale for tasks, opportunities for initiative taking and competence feedback that does not control or direct behavior are believed to be synonymous with positive motivational climates. If a coach can successfully adopt the prescribed behaviors linked to developing autonomy then they are likely to develop intrinsically motivated athletes that, invest more effort (Peltier et al,1995) report higher levels of concentration (Briere et al, 1995) are more persistent (Peltier et al, 2001) and perform better (Beauchamp et al,1996).”12) “As a coach, you can help an athlete develop this internal motivation by encouraging autonomy, self-efficacy, and relatedness.”

You Have to Understand Breathing to Understand Movement

13) Dave Tilly writes a very thorough breathing series (part 1, 2, 3).14) Jon Herting also has a solid breathing series (part 1, 2, 3)15) I’ll shamelessly promote my simple 2 part breathing series here as well (Part 1 & 2)

Tendinopathies

16) If you’ve been following this blog, then you know isometrics have been gaining popularity with respect to decrease tendon pain while providing safe mechanotransduction (#29, #3, #47, #20, #9,  #13, #3, Jill Cook, Andreo Spina Review).  More research (Heavy Slow Resistance, Reduced Cortical Inhibition) and blog posts (Body in Mind, Leon Chaitow - Mechanism) are now surfacing that will hopefully change the medical mainstreams bias of eccentric exercises for all tendinopathies.17) Tom Goom has some of the best tendinopathy posts here (stages, treatment 1, treatment 2).  Probably the best resources to share with your peers that may not know about tendinopathies.

Pain & Neuroscience

18) “The nervous system depends on consistent patterning in a non-threatening environment in order to best learn and perform. Patterns create security (though these patterns may not always be ideal). Security allows for one to pay attention and integrate sensory cues with minimal internal noise or distraction.” -Seth Oberst with another solid post on stress/threat (including some great clinical advice)19) A slightly ranty, but necessary, post by David Butler - “Overall, this is a call to be careful with Explain Pain – to understand what it is, as well as realise what it isn’t, to acknowledge the skills required to effectively deliver Explain Pain, and develop them where necessary, and finally, to recognise the need to think differently and more broadly, bringing in the rich world of education science and psychology, in the effort to achieve the very worthy goal of pain education for all.”20) Erson goes over a cervical case study and how he educated the patient on her pain.21) “A novel finding was that altered motor cortical organisation (number of discrete peaks and map volume) was associated with the severity and location of LBP.” #Smudging22) Psychology may work better than than traditional physical therapy for chronic low back pain.  This is what most pain science advocates have been saying for years.  The difficult part is training physical therapists to understand the complexity of psychology and communicate this with their patients in an effective way.23) “In fact, taking Tylenol can ease social pain just like it does physical pain. To your brain, they’re the same.” -Eric Barker on rejection24) Another reason why the shoulders and trunk are important in neck patients?25) You’re missing out if you haven’t signed up for ISPI’s Newsletter.

Memory

26) "The findings of both animal and human studies provide compelling evidence that stress-induced activation of the amygdala and its interactions with other brain regions involved in processing memory play a critical role in ensuring that emotionally significant experiences are well-remembered."27) Neural synapses store memories.  These synaptic connections last as long as the memories themselves.28) Todd Hargrove writes a great post on pain and memory - “I think one way that therapists can help clients with chronic pain is giving them a new way to frame past experiences of injury, and better ways to respond in an emotional intelligent way to new injuries.”

More on pain and memory - “It is concluded that pain induced by physical exercise is not remembered accurately and the pain and negative affect experienced influence recall.”

Research

38) Jeff Rich shared this great article on the subtle cavus foot and how to determine forefoot vs. rearfoot pathomechanics.39) It’s not just magnitude, it’s also about timing - “the application of a prefabricated foot orthosis with a 5° medial rearfoot wedge was associated with a significant delay in the timing of the peak knee abduction moment during the stance phase of running”40) “Synergistic muscles compensate for a fatigued muscle by increased muscle activity.”   Fatigue and compensation is a huge problem.41) Knowing about the Limbic System may help you understand the different responses people have to the same input.  “The monitoring role of anterior cingulate, the trisynaptic hippocampal circuitry underlying cognitive functioning and the significance of hypothalamus in various neurovegetative functions suggest the integral role of the limbic system in understanding human behavior and its aberrations.”42) “This study highlights the likely energy storage role of the ITB, which serves the purpose of increasing efficiency of human running. The anterior and posterior portions of the ITB store energy at different times, i.e. when they undergo stretch-shorten cycle during gait and this corresponds to high muscle EMG activity.”43) Did you know about the two different fiber types of the Subscapularis muscles?  “The line of action of the lower fibres are biomechanically advantaged for controlling or resisting excessive translation superiorly and anteriorly (especially in mid-range shoulder elevation). The upper fibres are advantaged biomechanically for producing internal rotation and horizontal flexion/adduction range of motion and force.”44) “Of 1283 survey respondents, only 27% of athletes reported using mental skills such as goal setting, positive self-talk, imagery, and relaxation. Of the 249 respondents who used mental skills 72% reported they felt it helped expedite their recovery process.”

This new finding may point to a way out of that vicious, anxious circle. Doing small good deeds for other people naturally turns your focus outward, which may leave less room for obsessive self-reflection.”49) Communication skills are often overlooked.  The Laddering Technique can be used to get to someone’s core beliefs and values.50) “Specifically, the study finds that people who walked for 90 minutes in a natural area, as opposed to participants who walked in a high-traffic urban setting, showed decreased activity in a region of the brain associated with a key factor in depression.”51) The Four Foundations of Mindfulness

Coaching & Cueing (Part 3 - External Verbal Cues)

The type of cue one chooses should be based on the environment, individual, and task.This article should help you understand when to best choose an external cue.External Cue: focuses on how the body’s output affects the environment (outcomes, objects, etc.) 

Science of External Cueing

External verbal cues (VC) have been the most commonly discussed type of cueing in the past decade. There’s a good reason: the latest research has provided some clear results that can have a major impact on coaching.

• “External focus allows the motor system to “self-organize”; efficiently coordinating and directing forces needed for accurate, maximal and sustained force production.” -David C. Marchant

Research shows:

External VC Are Better Than Internal VC for:

• Performance
• Skill Acquisition
• Complex Motor Tasks
• Multi-Segmental Motion
• Force Generation (summative, accuracy, endurance)

8 Benefits of External Cueing

1. Allows the Motor System to “Self-Organize”
2. Keeps Movement Reflexive and Automatic
3. Frees the Brain From an Extra Task - Constrained Action Hypothesis
4. Decreases Aberrant Muscle Activity = Less EMG Activity = Conservation of Energy
5. Less Co-Contraction
6. Increases Speed
7. Better Retention and Carryover
8. Produce Greater Force, Increased Accuracy of Target Forces, and Increased Duration of Force Production

How to Use External Cues

The most important aspect of external cueing is incorporating part of the existing environment.  Simply chose something that is NOT part of the individual (i.e. don’t reference muscles, kinematics, etc.).  It can be anything from a belt buckle to a location in the room.To achieve a more specific outcome, Nick Winkelman uses a 3-D approach to cueing.  He states that we need to cue Distance (close, far, etc.), Direction (away, towards, etc.), and a Description (push, snap, drive, etc.).Cue selection depends on a variety of factors including: environment, task, desired outcome, biomechanical movement, participants experience, readiness, etc.  Different cues will elicit different results.  “Drive the ground away” will be different than “punch the ground away”.  There are many external cueing choices for each movement. Which one you choose is where the “art” of coaching comes into play.

Analogies

Analogies also fall into the external cueing category.“Analogies allow us to convey technical complexity through the lens of relatable stories/experiences that are easy to understand.”-Nick WinkelmanFor example, during a single leg deadlift you can tell the patient to keep their belt/waistband level like an airplane (then add the visual cue of tilting your hand which way their pelvis needs to move in the transverse plane).

Choking

An interesting finding during my research was that one of the major causes of choking in sports performance comes from self-focused attention.  When the athlete is under a high stress situation, an internally focused point of view leads to decreased performance (choking).This is obvious when Tiger hits it into the rough after focusing on his glutes.  But it is less obvious when your frustrated medicare patient is losing balance while walking after trying too hard and focusing internally.  An external cue would help in both situations.

Deadlift Example

Lets go back to the deadlift example.  If you’re trying to increase the weight or speed of the movement, then you need an external cue - “push the ground away”.  This would allow the motor system to simply focus on providing the optimal output to accomplish the task based on the current variables.Internally cueing someone to contract their glutes would only clog up the brain and make the movement less efficient.  While this internal cue may not be bad during the learning phase for chunking purposes, it could be dangerous when the person is at the limits of his/her capacity (i.e. 1RM or in a fatigued state).

Summary

External cues are far superior to internal cues for various outcome results (performance, complex motor task, skill acquisition, force generation, etc.).  If you’re learning or performing a complex motor task, don’t clog up the processing with internal cues. Instead, use external cues to free the motor system to choose the most efficient and effective motor patterns.And don't overcomplicate things with too many words.

• “Say the most with the absolute least” -Nick Winkelman

Dig Deeper

Most of the research has been led by Gabriele Wulf.  She provides detailed explanations of the concepts associated with external cueing.  However, if you want to skip going through the research yourself, but want a deeper understanding, you should look to Nick Winkelman.  He has done a great amount of work to bring the message of the research on cueing to the Strength & Conditioning field.

1) Sure, it’s a dynamic system and the nervous system has a huge influence.  But you can’t dissociate the physicality of our world from the human body.  Simple biomechanics can have a profound effect on your patient’s movement.  Here’s an example of how the first class lever works to Increase Glute Med Activity.2) Don’t forget about the frontal plane aspect of the bunion deformity - “the degree of first metatarsal pronation is linearly related to the amount of medial deviation of the first metatarsal”3) Kathy Dooley goes over the Obturator Externus - “When this muscle is locked long, it will contribute to hip compression. Since the muscle travels from the anterior outer pelvis posteriorly to the greater trochanter’s inner fossa, it works as a sling with obturator internus to keep that femur jammed into the acetabulum. “4) “Short-term practice of LNB (left nostril breathing) improves vagal tone, increases HRV, and promotes cardiovascular health of medical students.”5) Here are the first two posts to my Coaching & Cueing Series

“In epithelial and muscle tissues, the water is squeezed out of the tissues, and then is sucked back in when the pressure moves on or is taken away. Like squeezing a sponge over the sink and then letting it fill again while doing the pots and pans, this is generally a good idea.”

“More time won’t help; more accuracy of placement will.”

9) For more on Foam Rollers check out #11, this quick literature review write up, and this layman friendly article on foam rolling tone with Doug Kechijian10) Here’s a very good article on crawling - “The increased “little brain” activity during cross-crawl, on top of the stimulation to the high-order thinking function of the frontal cortex, contributes to better balance and coordination, which becomes particularly important when kiddo starts to walk and develops an interest in sports.”11) One of the things I learned from Qi Gong was the Teacup exercise.  Here’s a unilateral version shared by Erson.  It’s pretty much good for everything from your hand to your spine.12) Eric Cressey shares a nice quick postural assessment story in #4.13) Inside the Mind of Charlie Weingroff - June Edition.  These have a lot of good stuff in them.  Example - “T=R Principle: If you are a good enough coach to train around an injury, then the most important part of human performance is fitness.  Because it’s resiliency to stress (aka fitness) that led to your injury in the first place. The only reason we need rehab is because we didn’t have training.”14) APTA shares some great information on Dry Needling15) Do you know your foot pathomechanics?  Forefoot varus can be a big problem - it can lead to hyperpronation and excessive internal rotation of the kinetic chain.16) I thought our profession was starting to understand the latest research on tissue deformation.  Then I had an eval last week who left her old PT because he left bruises on her back from trying to “break up knots and scar tissue”.  Don’t be that guy.  Read this and remember that it takes a ton of force (literally >2000lbs) to deform tissue 1%.  And share this with your peers!17) 5 things you should ask your patients from Erson18) “Considered another way, from the top down this time, if at the moment of heel contact the gmedius is delayed (as suggested in the study below from achilles pain), the pelvis is likely to drift laterally and this could cause a reactive inversion strategy of the rearfoot, and maybe even forefoot as well, as an instinctive measure to try and draw support beneath the laterally drifting body mass center of gravity.

32) Hip Thrusters are a great and easy exercise that can easily increase glute strength and improve lumbopelvic function.  However, I’ve noticed many people tend to perform this with terrible form.

33) I've been doing a lot of this stuff lately.  Top 10 Bodyweight Exercises From GMB - Squat, Frogger, Monkey, Cartwheel, Pull-Up, Bear, Push-Up, Hollow Body Hold, Scales, L-Sit, and Handstand.34) Don’t let the click baiting “butt wink” title fool you, this is some serious stuff.  Dean Somerset writes a great series on hip morphology and how it affects range of motion (Part 1, Part 2, Part 3).

“those with more acetabular anteversion (forward placement on the pelvis) had greater flexion range of motion and less extension, lateral placement of 45-55 degrees gave the best overall mobility, but a lateral angle of less than 45 degrees gave more flexion range of motion and more than 45 degrees gave less rotation capability. He even showed that if the femoral neck was thicken by 2 mm in diameter it significantly reduced the range of motion in all directions, irrespective of placement.”

“The recipe for deep squatting seems to be slight femoral anteversion combined with acetabular anteversion, lateral placement of less than 45 degrees, and a thin femoral neck.”

“If someone has a very high degree of mobility, the likelihood of their having a thin femoral neck and a shallow socket is pretty high. If they have all the mobility of a clam, they likely have a deeper socket and thicker femoral neck. This combination, regardless of orientation of the acetabulum, will limit the overall diameter of the conical range of motion of the hip due to earlier contact with the acetabulum compared to a thinner neck and shallower socket.”

35) Very informative read on blood flow restriction training from James McCarron - “Setting initial pressures of around 50 mm Hg, a target pressure of 150 mm Hg and using loads of 20-30% 1RM would appear to be best practice from the what data is showing us.”36) Eric Cressey goes over ways to increase your training density37) Dan Pope displays some great hanging scapula exercises.38) Dean Somerset has a nice logical article on unstable surface training.  Make sure to read Eric Cressey’s article on this topic as well.  Unstable surface training has a place in training, just make sure you find it and don’t force it.39) Gray Cook discusses the Squat vs. the Deadlift - I like the “coil the spring” concept.  For more information, check out this article.40) I still like Mike Robertson’s easy exercise introduction format:

41) “Potential productivity is a complex process which depends on integration and interaction of different systems and organs on different levels of organization: from biochemical to genetic to social.”  PP is determined by a host of physiological and psychological factors: genetics, gender, body mass, age, the state of health, energy systems’ power, capacity, and efficiency, the state of the neuromuscular apparatus, the psychological state, motivation, the climate, the season, work conditions, etc.’ -Pavel on work capacity42) It’s good that more people are starting to understand the importance of recovery.  Lance Goyke writes a piece with some advice on how to recover the other 23 Hours of the day that you’re not in the gym.43) Regretting winter decisions?  Me too.  Here’s Eric Cressey’s 15 tips for leaning out for the summer - “Avoiding liquid calories is the still, in my opinion, the biggest dietary game-changer most folks in the general population can implement.”44) 12 Ways to Make Better Exercise Choices by Eric Cressey.  #12 is one that is often overlooked and not discussed on social media.

Research

45) Watch this.  Then make your peers watch it.  Great talk on Evidence Based Medicine and why it can be “rubbish” - Trish Greenhalgh #PatientBasedEvidence46) Study on the kinetic chain influence on Serratus Anterior anterior - the best activation involved the anterior spiral line (serratus-external oblique-internal oblique-hip flexors/adductors).  This is pretty much gait.47)Craig Payne shares some gems from ACSM48) “Tendon microcirculation increases after ultrasound and vibration massage intervention concentrated on the Achilles tendon.” [Gasp] ultrasound can be useful?  Hipster PT’s won’t like that.49) Sometimes research is just good to help spread the word - “This study showed that a single bout of isometric training reduced PT pain immediately and for at least 45 minutes following. An insight into the mechanism was provided by the concurrent increase in cortical inhibition.”

For more on Isometrics for Pain Relief look at #1 here.

50) “Previously injured athletes demonstrated significantly reduced biceps femoris muscle activation ratios with respect to ipsilateral gluteus maximus, ipsilateral erector spinae, ipsilateral external oblique, and contralateral rectus femoris in the late swing phase. We also detected sagittal asymmetry in hip flexion, pelvic tilt, and medial rotation of the knee effectively putting the hamstrings in a lengthened position just before heel strike.”51) It’s sad that this may be news for some people in our profession - “Both hip as well as core strength were significantly correlated to frontal plane alignment during the single leg squat, especially hip abductor strength was an important predictor of the frontal plane kinematics.”52) Interesting article on plantar flexion static-stretching (SS)

“Hence the SS-induced impairments prior to 10-20 minutes post-warm-up may not impact competition performance.”

“The effects of prolonged and intense SS on the joint receptors might lead to inhibitory effects on motoneurons, such as autogenic inhibition and Type III (mechanoreceptor) and IV (nociceptor) afferents and Golgi tendon organ discharge, and their greatest effects can remain for 5-10 minutes (Behm and Kibele, 2007).”

‘In conclusion, the SS protocol effectively increased passive ankle ROM of the stretched limb. The increased ROM appears to decrease the muscle peak force and pre-activation; however these finding were only a temporary effect (less than 10 minutes after the SS protocol was applied). The decrease of jump height and impulse for the non-stretched limb suggests a central nervous system inhibitory mechanism from SS.’

53) “The bit of the brain that maps muscle change, changes when muscles change, and can be measured by muscle changes.” -Roger Kerry’s one line summary of this article54) Strength wins again!  Here’s a new study showing the importance of shoulder/neck strength in patients with tension headaches.  As Dr. Andreo Spina has says - “you can’t rub someone strong.” #Context55) “The rate of spontaneous regression was found to be 96% for disc sequestration, 70% for disc extrusion, 41% for disc protrusion, and 13% for disc bulging. The rate of complete resolution of disc herniation was 43% for sequestrated discs and 15% for extruded discs.”  This doesn't make sense to me.  Is it along the lines of if it's really bad it can only get better?  Does anyone know the time for disc regression?

Coaching & Cueing (Part 2 - The Categories)

We need to first clarify an important concept before we go into coaching and cueing:

• NOT ALL MOVEMENT REQUIRES COACHING

To Coach or Not to Coach

If someone is performing a movement/exercise correctly, all you have to do is shut your mouth and smile.If someone is performing a movement/exercise incorrectly, you should ask yourself two questions:

1. Do they need a different environment via a sensory change/coaching and cueing?
2. Is this a professional error?  Is this the right exercise for this patient at this time?

So if someone can’t perform the deadlift correctly, they either need some coaching and cueing (a sensory change) or they need a different exercise.

3 Types of Coaching

I break down coaching into 3 different categories:

• 1) Verbal - External & Internal
• 2) Visual - External & Internal
• 3) Proprioceptive

Each of these categories are a change of the inputs from the environment.  Each section has a specific attentional sensory focus.  Below is a brief introduction to each type of cue.  For a more in depth look at specific cueing types, stayed tuned for Parts III-IV in this article series.

1) Verbal

Verbal cues are by far the most common and one of the most researched coaching cues.

External Cue

Focuses on how the body’s output affects the environment (outcomes, objects, etc.)

Internal Cue

Focuses on the body processes and internal systems (muscles, kinematics, pressure, etc.)

2) Visual

Visual cues are rarely discussed in the coaching realm.  However, there are some interesting concepts in this category that can have a huge impact on your clients’ movement.

External

Influences movement through visual input (visual field, objects, orientation, demonstrations, eyewear, etc.)

Internal / Motor Imagery

“Motor Imagery is defined as an internal rehearsal or reenactment of movements from a first person perspective without any overt physical movement. From another perspective, MI, also known as kinesthetic imagery, is an active cognitive process during which the representation of a specific action is internally reproduced in working memory without any overt motor output” -Carl Gabbard and Ashley Fox

3) Proprioceptive

Proprioceptive cues are very common in both rehab and training (whether the practitioner knows it or not).  It’s a common sense type of approach that can have more profound effects than any other sensory change.  These proprioceptive cues can be divided into MANY different sub-categories.

• Postures
• Load
• Speed
• External Stimulation (tactile, tape, surface, footwear, etc.)
• Regressions
• Progressions
• Lateralizations
• Modifications
• Modulations
• [Insert Latest Terminology]

 

Summary

Which type of cue the patient needs depends on many factors.  A greater understanding of each of these types of sensory changes will help one determine which one to use.  Keep the overall goal in mind and match your desired outcome to they type of cueing.And remember, if someone isn’t performing a movement correctly despite your coaching/cueing, you either need a different sensory change or a different exercise.
