How your Brain sees your Body

The Sensory and Motor Homunculus Men

What is the deal with these weird looking figures? Why are they proportioned the way they are? Why the giant hands? And the oversized mouths? And what does it have to do with our brain? Lets investigate…

These figures are called the Sensory and Motor Homonculus Men. They are proportioned like this to illustrate how much of the sensory cortex and the motor cortex is devoted to sensing and moving the different areas of the body. So the hands and mouth are oversized because large areas of the brain are given over to operating the hands and mouth.

The Sensory Motor Cortex (below) is the part of your brain that deals with sensing (sensory) and moving (motor) your muscles.

The Sensory Motor Cortex

Different areas of the sensory motor cortex are responsible for sensing and moving different parts of your body. The diagram below is called a sensory motor homunculus, it maps out which parts of the sensory motor cortex sense and move which body parts. The sensory homunculus (blue) receives information from the muscles regarding muscle tension/length, joint angles, load etc. The motor homunculus (red) sends motor commands back to the relevant muscles based on the aforementioned sensory information.

Sensory Motor Homunculus Map

The commands from the motor cortex are a signal to the muscles to either increase the level of tension (contract), reduce the level of tension (relax) or maintain the level of tension. This back and forth of information, from the brain to the muscles, creates a sensory motor feedback loop. Sensory input arrives from the muscles into the sensory cortex > motor impluses exits the motor cortex and go back to the muscles > sensory input in > motor impulses out… and round and round it goes.

As you can see from the image above, your hands and face/mouth/tongue take up a huge part of both the sensory cortex and the motor cortex. Physically they may be small but neurologically they are massive. This makes sense when you begin to consider a) the many, many ways which we can use our hands and the very fine control we have over them and b) the fine control of the mouth, tongue and larynx that is required to speak.

Handwriting for example, requires a huge amount of brain processing power to be executed correctly. Perhaps that is why learning to write is such a laborious process. Writing, drawing, painting, playing an instrument, carving, pottery, sculpting all these activites require great skill and sensorimotor control of the hands. So to do any sort of fine work with the hands is to use and stimulate large portions of the sensory motor cortex of the brain. This suggests that the old saying “to be good with your hands” should maybe be understood as “to be good with your brain.” A point that is well illustrated in this interesting article that asks “Why does writing make us smarter?”

Interestingly the advent of computers, smartphones and touch screens has led to a sharp decline in real world hands-on skills being practiced. Now we seem to do everything virtually, on a computer screen. We have begun to use our hands mostly to tap keys and swipe screens, and in doing so we have reduced somewhat, the amount of stimulation that the sensory motor cortex receives. If we are not using our hands to their full potential, then maybe we are not using our brains to their full potential. I wonder what the long term implications of this will be on us and our society? As the old saying goes “Use it or lose it”. Only time will tell.

But for now let’s get back to the sensory motor cortex. As noted previously, another very large portion, approximately one third of the sensory motor cortex, is devoted to the sensing and controlling of the face, mouth, lips, tongue and larynx. Again this makes sense when we consider that as humans we speak. Speech requires a great deal of brain power to orchestrate. The lips, tongue and larnyx have to coordinate with our diaphragm in order to deliver intelligible speech or in a further refinement, to sing.

So with one third of the sensory motor cortex dedicated to the hands and another one third of the sensory motor cortex dedicated to the face/mouth/lips/tongue/larynx, there is only one third left. Just one single third of your sensory motor cortex devoted to the largest parts of the body! Your trunk, spine, hips, shoulders and limbs.

That is comparatively a very small section of the sensory motor cortex that is responsible for sensing and moving a very large area of the body.  Is it any wonder then, that the areas of our bodies that have the least cortical (brain) representation are the same areas that are most susceptible to movement deficits and muscular pain? Back pain, hip pain, shoulder pain anyone?

The trunk, hips, shoulders, and neck are supported by a very small section of the cortex. This means less processing power for a large area of the body. This being the case it would make sense that we might have to spend a little more time maintaining our brains control over these parts of our body, making sure the modest amount of the sensory motor cortex that is apportioned to these areas is stimulated regularly.

Movement of all and any kind provides massive amounts of stimulation and sensory information to the brain. We traditionally think of information as purely intellectual, words, numbers, facts, data etc. But for your sensory motor cortex, MOVEMENT IS INFORMATION. And the more information your brain has about your body, the better you can sense and organise your movement.

So how can we help ourselves in this regard? A Somatic movement practice is a great place to start. Practicing somatic movements slowly and smoothly allows us to re-establish, maintain and refine our sensory awareness and our motor control. By relearning how to move our trunk and spine comfortably through their normal and natural ranges of motion. Then when basic control has been re-established, we can get on with enjoying our favourite acvtivities whatever they may be. (Running, walking, lifting, climbing, dancing, yoga, gardening, tennis, the options are endless).

You can start learning how to do all this right now by checking out the Learn Somatics YouTube Channel.

Can Stress Management be Simple?

Photo by Aarón Blanco Tejedor on Unsplash

Stress. It’s unavoidable. No matter your circumstances you are going to experience, and have to manage, some degree of stress in your life. But what is stress?

“Stress has many faces, and creeps into our lives from many directions. No matter what causes it, stress puts the body and the mind on edge. It floods the body with stress hormones. The heart pounds. Muscles tense. Breathing quickens. The stomach churns.
The body’s response to stress was honed in our prehistory. Collectively called the “fight-or-flight” response, it has helped humans survive threats like animal attacks, fires, floods, and conflict with other humans. Today, obvious dangers like those aren’t the main things that trigger the stress response. Any situation you perceive as threatening, or which requires you to adjust to a change, can set it off. And that can spell trouble.
Chronic stress can lead to high blood pressure and heart disease. It can dampen the immune system, increasing susceptibility to colds and other common infections. It can contribute to asthma, digestive disorders, cancer, and other health problems. New research even supports the notion that high levels of stress somehow speed up the aging process.
Though stress is inevitable, you can help control your body’s response to it. Exercise, meditation, invoking the relaxation response, and mindfulness are great stress busters.”
https://www.health.harvard.edu/topics/stressSource

From the above, the point we’re most interested in is this: “Muscles tense.” What they are saying is that stress causes involuntary muscular tension. That’s a problem. This muscle tension happens subconsciously. We are not really aware of it. This muscle tension, as well as making us feel stressed, can lead to chronic muscle pain and stiffness.

When the body is stressed, muscles tense up. Muscle tension is almost a reflex reaction to stress… https://www.apa.org/helpcenter/stress-body

This also leads to automatic activation of the SYMPATHETIC nervous system (‘fight or flight’ response). The physiological effects of activation of the SYMPATHETIC nervous system (SNS) include:

• ACCELERATED Heart Beat (anxiety anyone?)
• HIGH Blood Pressure (uh oh)
• INHIBITED digestion (hello belly ache)
• RELAXED Bladder up (I never used to make night time trips to the bathroom?)
• CONTRACTED Rectum (why am I constipated?)
• Secretion of STRESS HORMONES from the adrenal glands (I can’t shake this bad mood)
• SUPPRESSION of the immune system (why am I always sick?)
• REDUCED growth (suppression of growth hormones) (that little cut still hasn’t healed)
• SLEEP PROBLEMS (so tired all the time)
• MEMORY DYSFUNCTION (sorry, I totally forgot about your birthday)

Doesn’t sound like much fun does it?

Do any of these sound familiar to you? If so, you may be suffering from some degree of chronic stress and the chronic SNS activation that goes along with that. SNS mode is not necessarily a negative state, as indicated above it is necessary to respond to a threat/situation appropriately. The problem is when we find ourselves in a state of chronic SNS activation. As humans, we are well-equipped to deal with short periods of SNS activation, then ideally, when the perceived threat has ended, we would return to PARASYMPATHETIC Nervous System (PNS) activation. PNS is, or should be, our default mode (also known as ‘Rest, Digest and Repair’ mode).

PARASYMPATHETIC nervous system activation has the opposite effects to the Sympathetic Nervous System:

• SLOWER heart beat (feeling calm…)
• LOWER blood pressure (…and relaxed…)
• STIMULATION of digestion (…and well nourished)
• NORMALISED bladder function (no more getting up in the night)
• RELAXATION of rectum (regular as clockwork)
• INHIBITS secretion of STRESS HORMONES from the adrenal glands (happy mood, happy days)
• STIMULATION of the immune system (I can’t remember the last time I was sick)
• NORMALISED growth hormone responses (that cut has healed right up)
• DEEPER more restful sleep (Zzzzz..)
• NORMALISATION of memory functions (I planned a surpise for your birthday)

That all sounds much more conducive to feelings of relaxation right?

But how do we switch back to PNS mode, or ‘invoke the relaxation response’ when we are chronically stressed?

Well, if you could somehow release the involuntary muscular tension that is triggered in response to stress you could deliberately switch back to PARASYMPATHETIC nervous system mode. Somatic Movements provide us with a simple and straight forward way to do just that. They use a technique called pandiculation to reduce muscular tension (and reduce pain and improve movement, bonus!). Pandiculation works by re-establishing your voluntary control over your muscles and in the process, relaxing them. This leads to de-activation of the SYMPATHETIC nervous system (fight, flight or freeze mode) and activates the PARASYMPATHETIC nervous system (rest, digest and repair mode).

This makes Somatic Movements a simple and effective stress management tool. By learning how to monitor, regulate and control your own muscle tension you are learning how to monitor, regulate and control how you respond to stress. With practice you can become more resilient to the myriad effects of stress. You can literally learn how to relax, and activate your Parasympathetic Nervous System, any time, on demand. Becoming an expert at relaxing. Sceptical? Take less than 3 minutes and try a pandiculation right now by listening to the audio below;

The pandiculation technique utilised in the audio above can be applied to all the muscle groups in the body for total body relaxation. By deliberately releasing the muscle tension triggered by stress you can return to a state of relaxation and calm. When you are relaxed you can sleep better, when you sleep better you will feel more refreshed, when you are more refreshed, you can think more clearly, when you think more clearly you can make better decisions, when you make better decisions… well, who knows what good things might happen!

When stress is unavoidable, simple, effective stress management techniques become essential. So why not Learn Somatics? You’ve nothing to lose… except all that tension.

More Thoughts on Posture

Posture is the upright organisation of the body in gravity. It is how we hold ourselves when we are not actively thinking about it. Therefore posture is a subconscious process. Hence why telling someone to ‘Stand up straight!’ is an exercise in futility.

Working in the realm of Hanna Somatic Education, we look for signs of the Three Reflexes in clients’ posture. Green Light Reflex (Spinal Extension), Red Light Reflex (Spinal Flexion) and Trauma Reflex (Lateral Spinal Flexion/Extension, Spinal Rotation). These Reflexes are brain events, that is to say they are automatic motor responses originating in the brain, affecting skeletal musculature, instructing that musculature to contract/tighten into an observable pattern.

Posture indicates what the Nervous System is doing at the involuntary/subconscious level. When we assess posture we are assessing subconscious brain activity. Posture is a finger pointing to the moon (or brain in this case!).

“It’s like a finger pointing a way to the moon, don’t concentrate on the finger or you will miss all that heavenly glory” Bruce Lee, Enter the Dragon

For example, consider a very stooped posture, with rounded shoulders and head forward, flat lower back and pelvis tucked under. This would be indicative of Red Light Reflex (Spinal flexion). I do not think the person has ‘bad’ posture or that they need to strengthen their muscles of extension. I merely note that their nervous system at the subconscious level, is drawing them into the pattern of flexion. If this is the most prominent pattern of contraction of their posture or process, it gives me a starting point from which to work.

Once we begin to see posture not as a result of biomechanical structure but as a result of continuous subconscious brain output, we can change our approach. The focus shifts upstream to the brain, not down stream to the muscles and/or bones. Now the goal will be to change subconscious nervous system output. New problem, new solution.

So how do we change this continuous subconscious brain output? The answer is surprisingly simple. The client must voluntarily go into the subconscious pattern of contraction. Make the involuntary, voluntary. Make the unconscious, conscious.

By choosing to contract into the pattern of tension deliberately the client regains voluntary control of all the musculature involved.  Patterns of muscular contraction are primary, as this is how the brain reflexes are expressed. Groups of muscles, contracting into general, observable and consistent full body patterns. These voluntary muscular contractions, into the full body pattern, send new sensory information all the way to the sensorimotor cortex, the movement learning part of the brain. Once the client has reestablished voluntary control of the musculature involved in the pattern, they can sense it, ‘feel’ it contracting, they now have three options available to them;

1. Increase the level of contraction in the musculature, going further into the pattern
2. Maintain the level of contraction in the musculature, holding the pattern
3. Reduce the level of contraction in the musculature, relaxing out of the pattern

In this instance, the best choice is to select option 3, to reduce the level of contraction and relax back to rest. This act of voluntary contraction, followed by slow voluntary relaxation and then a moment of complete rest,  is called a pandiculation. You can find a detailed description of pandiculation here.

By pandiculating several times, the client can quickly learn to become proficient at contracting AND relaxing these muscles that unconsciously have drawn them into a full body pattern of contraction (flexion in this example). This act of pandiculating changes nervous system output at the brain level, reducing motor output to the muscles involved in the pattern. When the nervous system activity changes, the muscles involved in the pattern relax and the posture follows along.

The goal is not to change the posture, the goal is to change the habitual/unconscious motor output of the nervous system. The posture shifts or changes as a result of reducing unnecessary nervous system motor output. Postural changes are a by product of practicing Somatics rather than a goal.

It’s Never Just One Muscle

Often, when we have pain, there is a perception that there is one particular muscle that is causing the problem. Such as, “Oh its my psoas/piriformis/hamstring” etc. And while that may be where you feel the pain or restriction, it is not necessarily where the problem is.

Muscle never work in isolation, they can’t. In order for one muscle to contract, another, opposing muscle must relax, this immediately means you have another muscle brought into play. Muscles work in groups and fire in patterns of contraction to facilitate movement. So a sore or tight psoas/piriformis/hamstring is really just one part of a much bigger habituated involuntary full body pattern of contraction. In Somatic Education we call this Sensory Motor Amnesia.

The Three Reflexes we work with in Somatic Education; Green Light Reflex, Red Light Reflex and Trauma Reflex, are examples of universal full body patterns of muscular contraction. These reflexes are common to all creatures with a spine and nervous system so it is important to be able to recognise them in yourself.

It’s that pesky hamstring again! Or is it?

From a Somatics perspective, we look for the connection between the problem/pain area and the three Reflexes mentioned above. For example tight/sore hip flexors, could be as a result of habituated Red Light Reflex. If it is only the hip flexors on one side, or perhaps the piriformis on one side, it may suggest a Trauma Reflex. A chronically tight and painful lower back can be caused by habituated Green Light Reflex. In order to address problems like these you must first relax the muscles of the relevant reflex and then improve the functioning of the entire movement system. As a living, breathing, conscious Soma* you are a SYSTEM OF MOVEMENT. Movement dysfunctions must be addressed by looking at that system in its entirety and improving its functioning in its entirety.

How is this done? Well, first we look at posture for signs of habituation of the Three Reflexes. Usually all are present to some degree. In that case which one is most dominant? What way is the brain and nervous system holding the body? Looking at the entire system.

We watch the client walking. What parts of the body move freely, which parts of the body do not move freely? Which side bears more weight? Again, we are looking at the entire system.

Then we palpate, that is we feel the tonus or hardness of the muscles, both standing and on the plinth/worktable. Are they tight? Which ones are tight? Which ones are soft? What is the relationship between them? What changes in the tonus from standing to laying down? Where is the Sensory Motor Amnesia (SMA)? Again looking at the entire system.

Then we decide which reflex to address first based on our observations. With that decision made we educate the client through gentle guided movement patterns and full body pandiculations. They learn how to sense the Three Reflexes (see links above), these universal full body patterns of contraction. How to recognize them, how to contract into them VOLUNTARILY and more importantly, how to RELAX out of them VOLUNTARILY.

Working in this way, by educating the client, allows for systemic improvements in movement, comfort and pain reduction. Because clients learn how to do these movements for themselves, they can repeat the process at any time by themselves. Thus becoming more self aware, self correcting and independent.

So with all that said. Do you have a muscle that seems to be tight or sore? If so, explore your movement a little further. Which parts of your body move freely and comfortably? Which parts do not move freely and comfortably? With a little investigation you may find that it is never just one muscle.

New Year, New Resolutions, New You?

At this time of year many people start thinking about New Year Resolutions. Often these resolutions will involve getting fit or losing weight. Your success or ability to lose weight and/or get fit will be intrinsically linked to your ability to move well. We get fit by moving and we lose weight by moving. If we cannot move well and without pain our chances of fulfilling these particular goals are slim… pardon the pun!

So with that said it would make sense to address your ability to move and perhaps make improving your movement one of your new years resolutions. When you can move well and without pain you will be more inclined to continue with your chosen exercise regime/activity. You will also be less likely to pick up an injury that might scupper your progress.

Moving freely and without pain is the foundation stone upon which you can build your new healthier lifestyle for the new year. Somatics is all about improving your movement. A daily somatics practice will lead to;

Pain relief: You are unlikely to keep up a new fitness regime if you have pain. Somatics can resolve your chronic pain issues (read more here)…

Improved movement: Somatics improves your movement by eliminating Sensory Motor Amnesia leading to greatly improved movement (read more here)…

Improved posture: When you release and relax you muscles your posture improves automatically (read more here)…

Improved balance, coordination and proprioception: When you can contract and relax all your muscles voluntarily you will have better control of your whole body (read more here)…

Improved sleep: When your muscles are relaxed it is easier to fall asleep and stay asleep (read more here)…

All of these benefits will go a long way towards helping you achieve your fitness or weight loss goals for the new year. If you would like to learn some of the most fundamental Somatic Movements right now you can head over to the Learn Somatics YouTube Channel where I’ll be adding more movements weekly.

Or perhaps you’d like to learn from me directly. No problem, check out my online learning options here. I’d love to help you.

Whatever your goals, have a happy, healthy and active new year!

Somatic Movement – The Basics and some Resources

In my last post I talked about the difference between stretching and Pandiculation. Based on the number of emails I received in relation to that article I want to clarify how Pandiculation relates to the other main elements of Somatic Education which are;

Sensory Motor Amnesia (SMA)

&

The Three Reflexes (Green Light, Red Light and Trauma)

You can’t fix a problem that you are not aware of. In the context of Somatic Education, Sensory Motor Amnesia is the problem, the Three Reflexes are how the problem presents and pandiculation is (one of) the tools we use to address and resolve the problem.

Everyone has some degree of SMA, from a little to a lot. Read more about what SMA is and how it develops, here.

SMA shows itself in the body as habituated contraction of Three Reflexes. These are brain reflexes, if you are conscious and reading this, then you have a brain, and if you have a brain, you will be susceptible to habituation of these three reflexes. I encourage you to read the three blog entries on each of the reflexes.

Here they are;

Green Light Reflex

Red Light Reflex

Trauma Reflex

When we habituate any or all of the Three Reflexes we will inevitably have movement deficits and/or muscle pain. The extent of either will be dependant on the subtlety or severity of our Sensory Motor Amnesia. Regardless, the approach to resolving the SMA is the same. We must remind the brain how to use the affected musculature correctly. We do this by voluntarily recreating the Three Reflexes and then slowly decreating them.

In the case of Green Light Reflex, this involves  purposely contracting the muscles of the Green Light Reflex, which is all the muscles of the back of the body. This allows us to take voluntary/deliberate/conscious control of those muscles, and then voluntarily/deliberately/consciously relaxing them slowly and under control. This simple act of pandiculating reduces the resting level of tension in the muscles for better movement, reduced pain and improved comfort.

Below is my video demonstrating a simple Somatic Movement to address Green Light Reflex, pandiculating the muscles of the back of the Spine, with an emphasis on the lower back muscles. I would advice watching the video first and then doing the movement whilst listening again.

Here is another simple Somatic Movement that addresses Red Light Reflex. Again watch the video first and then do the movement whilst listening to the video.

As you can see from the videos, Somatic Movements are performed, slowly and gently with the intention of something like a yawn. Try these out and leave a comment on your experience.

You can find more of my free videos on the Learn Somatics YouTube Channel where I will be breaking down all of the most fundamental Somatic Movements.

Stretching Vs. Pandiculation – What’s the difference and why does it matter?

Let’s look at the key differences between stretching and pandiculation. Pandiculation is used extensively in Clinical Somatic Education to regain the brain’s control of tight painful muscles.

Stretching sends sensory information only as far as the Spinal Cord
When a muscle is stretched, the sense receptors within that muscle send information to the spinal cord to indicate that the length of the muscle has changed, in this case lengthened. The spinal cord in response sends an impulse to the muscle being stretched, triggering a contraction (tightening), it also sends an impulse to the opposing muscle inhibiting a contraction. So, stretching a muscle causes it to respond by contracting. This is counter to what you’re are trying to achieve when you stretch. This is a very basic explanation of the stretch reflex. As you can see the brain is not involved in the process at all, the stretch reflex is a spinal cord reflex.

Pandiculation sends new sensory information all the way to the Brain
When a muscle is contracted voluntarily, the sense receptors within that muscle send information all the way to the Sensory Cortex of the brain (see image below) to indicate that the length of muscle has changed, in this case shortened, and also that the level of tension in the muscle has increased. Because this information has reached the brain, the muscle can be sensed or ‘felt’. It is also now under your conscious control. At this point you can choose to increase, maintain or decrease the level of contraction. When pandiculating you will slowly decrease the level of contraction all the way down to complete rest. But the take home point is that you establish full cortical control over the muscle when you contract it voluntarily.

Stretching is passive
Stretching is passive, you are not actively using the muscle, you are merely pulling on it, there is no brain involvement, the entire process is mediated by the spinal cord.

Pandiculation is active
During a pandiculation you are actively and deliberately contracting the muscle, your sensory motor cortex is involved in the process.

~

Stretching decreases potential power output of  the muscles involved
Passive stretching and even PNF* stretching temporarily reduce the potential power output of the muscle.

Pandiculation increases sensation & awareness of the muscles involved
Pandiculation strengthens the connection between the sensory motor cortex of the brain and the muscle. The muscle can be sensed more clearly and control of both functions of the muscle (contraction and relaxation) are increased. This is because the muscle is both contracted voluntarily and slowly relaxed volunatarily during a pandiculation, essentially allowing you to practice both contracting AND relaxing.

~

Stretching provides no new sensory information to the brain
Because the brain is not involved in a passive stretch there is no new sensory information for the brain. Therefore no new learning takes place. This may be the most important difference between stretching and pandiculation

Pandiculation provides lots of new sensory information for brain
Because the brain is very much involved in the process of Pandiculation there is a large amount of new sensory information for the brain. Therefore new learning takes place.

~

Stretching can be painful
Passive stretching is generally uncomfortable and can even be painful especially if Sensory Motor Amnesia (SMA) is present.

Pandiculation feels good
Pandiculation performed correctly feels very pleasurable and relaxing. It has the feeling of a yawn.

~

No attention required to stretch
There is no focused attention required to pull on a limb and evoke a stretch.

Attention required to paniculate effectively
Focused attention is absolutely required to perform an effective Pandiculation, both to contract the desired muscle and also to control the slow relaxation phase so that it feels smooth.

~

Temporary change in length
Passive stretching confers only a temporary change in length, if any, as the muscles reflexively recontract in response to the stretch.

Long term change in length
Pandiculation confers more permanent changes in muscle length as you brain LEARNS a new longer resting length for your muscles. Please note the changes in muscle length that are achieved through pandiculation are as a result of the reduced level of tension in the muscle. They are not as a result of tissue remodelling.

~

Stretching does not eliminate Sensory Motor Amnesia
Passive stretching does nothing to eliminate the habituated levels of chronic muscular contraction that are typical of Sensory Motor Amnesia (SMA).

Pandiculation eliminates Sensory Motor Amnesia
Pandiculation eliminates SMA quickly and easily by returning control of the muscle to Sensory Motor Cortex and allowing you to learn how to relax and lengthen your muscles.

These are the main differences between Stretching and Pandiculation. One final point to note is that often when people stretch they will stretch muscles in isolation, whereas with pandiculation one contracts many muscles at once. This allows us to release large patterns of contraction more quickly and effectively.

The learning component of pandiculation allows you to develop better sensorimotor control over your muscles, and muscles that you have full control over will not cause pain. It is only those muscles which you have lost control over that become chronically tight and painful. The pain is the warning sign that you do not have control any more.

It is important to note that there are scenarios where some form of stretching is required, such as in the practice of dance, martial arts, gymnastics etc. In these activities a high degree of flexibility, beyond what is considered normal, is required to perform certain techniques. However it is known and acknowledged that muscle tension must be normalised before stretching of this kind take place.

“In instances of excessive tension (excessive neural stimulation) or weakness (excessive neural inhibition) caused by misaligned joints or neurological problems, typical strength training exercises will not help you either… …To fix such problems you need the help of an applied kiniesology specialist who, among other modes of treatment, may prescribe special exercises for normalizing the tension of muscles”

Kurz, T. (2003) Stretching Scientifically p.11-12

Furthermore this kind of high level flexibility is best attained through the intelligent application of dynamic stretching, static active stretching, isometric stretching etc. If this is something you are interested in I highly recommend the book quoted above; Stretching Scientifically, By Thomas Kurz.

Interestingly, when we research the different methods of stretching it becomes clear that the most effective methods of stretching all favour preceding a stretch with some kind of muscular contraction.

The ‘excessive tension’ noted in the quote above is no different to the Sensory Motor Amnesia we recognise in Somatic Education. And Somatic movements can perfectly fulfil the role of the ‘special exercises for normalising the tension of muscles’. Once muscle tension has been normalised, other methods of stretching can be implemented safely and more effectively in accordance with your goals.

To be clear, there is nothing wrong with stretching, but we need to understand what we are trying to achieve, and what is the best tool for the job. If muscle tension is already excessive, pandiculation will serve you better than stretching. Once muscle tension has been normalised, you can begin to explore other methods of stretching again if you wish. However for most people, Somatics can provide you with the requisite mobility to be comfortable in your day to day activities.

Habituation – How our movement habits can create our pain

How can our movement habits create pain and decrease our ability to move well?

Habituation is the simplest form of learning. It occurs through the constant repetition of a response. When the same bodily response occurs over and over again, its pattern is gradually “learned” at an unconscious level. Habituation is a slow, relentless adaptive act, which ingrains itself into the functional patterns of the central nervous system. (Thomas Hanna, Somatics 1998)

We get good at what we repeatedly do, that is how our brain learns, through repetition. We will get good at things we do intentionally AND things we do unintentionally. If we repeatedly stand in a certain way or walk in a certain way, eventually that way will become learned and automatic. When it becomes automatic we are no longer conscious of it. It becomes our ‘normal’.

The Green Light Reflex is the reflex that drives us forward into the world. It is an inherently positive reflex. Without it we would never have learned to crawl or walk. However, every time your phone rings, someone calls your name, a deadline looms, you rush to be on time, the bodily response is the same, your Green Light Reflex is triggered. All the muscles of the Green Light Reflex contracting, to ready you for action.

In modern society, most people have very busy lifestyles and are constantly under demand from their jobs, children, emails, phone calls, text messages, social activities, hobbies etc. This constant triggering of the Green Light Reflex, leads to habitually and chronically tightened back muscles in exactly the way described by Thomas Hanna in the quote above.

Your ‘normal’ becomes a learned state of contraction, always ready for action and unable to relax fully. You develop Sensory Motor Amnesia (SMA), forgetting how to release and relax all the musculature of the back of the body. A stiff, sore back and reduced ability to move freely becomes inevitable at this point.

The Red Light Reflex is the complete opposite of the Green Light Reflex. It is a withdrawal reflex, a tightening of all the front of the body in an attempt to make ourselves small and hideaway from fear or danger. Red Light is triggered by fear, danger or threat, .ie when we hear a loud noise, or someone yells ‘duck!’. It can equally be caused by spending too much time slumped in front of a laptop, tv, tablet or smartphone. Nowadays this seems to be a major cause of Red Light Reflex. Many hours with our heads pointed down, back rounded and our shoulders slumped forward gazing at our ever smaller screens (PCs > laptops > tablets > smartphones). If we spend a lot of time in this position, or under threat, we are essentially learning how to stay in that position. Belly tight, hip flexors tight, shoulders forward, head down. Again this state of learned contraction becomes our new ‘normal’. And while it is very useful for looking at gadgets or working at a screen, it is not so useful when we want to do something (anything) else. Eventually, you develop Sensory Motor Amnesia (SMA), forgetting how to release and relax all the musculature of the front of the body. A stiff, sore neck and shoulders and reduced ability to breathe deepy and move freely becomes inevitable at this point.

We can habituate any posture or movement pattern that we use regularly, whether it is helpful or not.

Think about it, do you always sit in the same chair in your living room? In the same position? It just feels comfortable right? Well that’s because you have unintentionally learned to sit in that way. It’s an example of habituation. Do you always carry your infant on the same side hip? Habituation. When you drive do you always sink into one side? Or put your elbow on the centre console? Habituation. When you stand do you always cross your arms? Or your legs? Or lean into one side? How do you walk? Always wear your bag on the same side? Again these are all habituations. One sided habits can lead to Trauma Reflex. Much of what we do each and every day is automatic and performed unconsciously. But some of these movement habits may be causing you to have pain due to the constant contraction of the muscles involved.

Becoming aware of our movement habits can help us to identify which ones may be causing us to have pain or reducing our ability to move well. Once identified, Somatic Exercises or Clinical Somatics Lessons can help us to release these habituated patterns of muscular contraction for less pain, more self awareness and more freedom of movement.

Low Back Pain and Green Light Reflex

In this post, I described The Green Light Reflex. When this reflex becomes habituated, it can often cause back pain, particularly in the low back.

But how does the Green Light Reflex cause back pain?

When the thick strong muscles of the spine, known collectively as paravertebrals, are involuntarily stuck in contraction (SMA) they draw the spinal vertebra closer together, this causes the lower back to arch forward excessively. This is often referred to as lordosis, or lordotic posture. It is easily identified by a lower back that is pulled to the front, it also makes the belly protrude and tilts the pelvis anteriorly.

Neutral posture (left), and a typical Green Light posture (right)

 

Some points to notice, in the figure on the right.

1. The excessive arching of the lumbar spine
   
2. The change in angle of the rib cage and pelvis due to the tightening of the back muscles
   
3. The drawing drawing back of the shoulders and head
   
4. The corresponding forward position of the hips
   
5. The hyperextension of the hips and kness
   
6. The protuding of the belly as a result of the overarched low back

When these paravertebrals are stuck in contraction, they will make any type of forward bending action more difficult. In order to bend forward freely, you must be able to relax and lengthen all the muscles along the back of the spine. If you cannot voluntarily relax and lengthen these muscles you have what we call in Clinical Somatic Education, Sensory Motor Amnesia (SMA).

Paravertebrals

 

Paravertebrals (the muscles running either side along the length of the spine) that are habitually contracted pull the vertebra (bones of the spine) closer together. This can compress any or all of the nerves that exit the spinal cord in the lumbar area or any other area of the back, leading to trapped nerves, sciatica or similar complaints.

This compression of the spinal vertebra can also create a situation where the intervertebral discs that are supposed to act as shock absorbers between each vertebra, are pushed out of place leading to bulging/herniated discs. This spinal compression is also what causes “wear & tear” in the lumbar spine. Even if you don’t have nerve pain or bulging discs from habituated Green Light Reflex, the constant contraction of the paravertebrals leads to fatigue and aching muscles in the back.

So an habituated Green Light Reflex can be the cause of several problems from a reduction in mobility all the way to herniated discs. Each of these problems occur along a spectrum of Green Light Reflex. At the low end of the scale, .ie minimal green light reflex you might expect to have reduced forward bending ability, and at the high end of the scale you might expect, tension headaches, chronic pain and bulging or herniated discs.

These are not the only issues that can occur as a result of habituated Green Light Reflex. It can also lead to tension headaches, neck pain, shoulder pain, tight hips, hamstrings and calves, knee pain and other issues. But the mechanism by which these problems occurs is the same. Chronic involuntary contraction (SMA) of all the muscles of the back of the body. In the image below those muscles are highlighted in green.

So what can we do about it? Well in truth the solution is quite simple. We must RELEARN optimal control of all the muscles of the back of the body. When we relearn proper control we will have the ability to relax and lengthen these muscles to their full and proper resting length. When this has been achieved pain is reduced or eliminated and movement quality improves.

How do we relearn proper control of these muscles? We pandiculate them using safe simple Somatics Exercises or through a series of Hands On Clinical Somatic Lessons. If you would like to learn how to release and relax all the muscles of the Green Light Reflex for a looser more comfortable back and freer movement, try one of my online classes here.

Neck and Shoulder Pain and The Red Light Reflex

How does The Red Light Reflex cause, neck pain, shoulder pain, back pain, problems in the arms and wrists , shallow breathing and poor posture?

Red Light Reflex is an habituated and ongoing tightening of all the muscles of the front of the body. When you forget how to relax and lengthen the muscles of the front of the body you can develop many problems over time. In Clinical Somatic Education we call this inability to release and relax muscles Sensory Motor Amnesia (SMA). With Red Light Reflex the main muscles involved are the muscles of the belly (Abdominals), chest (pectorali major and minor), shoulders (upper trapezius) and inner thighs (adductors). So how does involuntary chronic tightness in these muscles lead to pain and poor movement?

Neutral posture (left), and a typical Red Light posture (right)

 

Some points to notice, in the figure on the right.

1. The forward curving of the spine
   
2. The change in angle of the rib cage and pelvis due to the tightening of the belly and chest muscles
   
3. The drawing together of the rib cage and pelvis due to the tightening of the belly muscles
   
4. The corresponding forward position of the head and the shoulders as a result
5. The bending of the legs and arms
   
6. The reduction in true height as a result of the spinal curve

 

Back Pain
As you can see from the image above Red Light Reflex causes a curving forward of the spine. This creates a situation where the back muscles are always lengthened but at the same time working hard to keep you upright in gravity and maintain your head position. This constant workload creates sore, tired back muscles and leads to pain in the mid and upper back.

Neutral posture, absence of Red Light Reflex >>>>> Red Light Reflex

 

Some points to notice, in the figure on the right.

1. The sunken chest, rounded back and shoulders forward
   
2. The head pulled forward of the centre line

 

Neck and shoulder Pain
When the belly, chest and frontal neck muscles are tight making the spine curve forward, they draw the head and shoulders forward too (refer to images above), creating a rounded back and stooped posture. This makes it difficult to stand up “straight”. The constant forward and shrugged position of the shoulders can also cause discomfort and pain whilst limiting your ability to turn your head left or right and also to raise you arms straight overhead. The shoulders must rest in a neutral position in order for the neck and arms (and in turn the elbows and wrists) to move freely and function properly. When the shoulders and head are constantly drawn forward this reduces the amount of space internally in the front of the chest and neck. This means less space for all the nerves and blood vessels which innervate the shoulders and arms. When these nerves and blood vessels are compressed or inhibited it leads to problems in the…

Arms, Elbows, Wrists and Hands
Problems in the arms, elbows, wrists and hands are also often due to habituated Red Light Reflex. The brachial plexus, which is the main nerve that innervates the (upper limbs) arms runs between the scalene muscles of the neck, through the area behind the collar bone and just behind the attachment of pec minor (small blue chest muscle in image below) towards the armpit. When the chest and neck muscles are habitually contracted, as is the case with Red Light Reflex, they can compress the brachial plexus causing; Thoracic Outlet Syndrome, tingling and numbness in the arms and hands, weakened grip, carpal tunnel syndrome, cold hands etc. This is yet another example of tightness in the centre of the body leading to problems at the extremities.

Breathing
You can also see in the image below the intercostals, these are the muscles that are found in between each of the ribs. In Red Light Reflex these muscles will also be habitually contracted to some degree. As you can imagine, if these muscles cannot relax fully your ability to breathe deeply is reduced. In this situation the ribs are no longer free to expand making space for the expanding lungs. As a response to this we begin to chest breathe which adds further fatigue and tightness to the muscles of the chest, neck and shoulders. Chest breathing is inefficient and can cause systemic low level anxiety and fatigue due to insufficient oxygen intake. Belly breathing in contrast is efficient and helps you feel relaxed and energised. Belly breathing is only possible when we are able to let our abdominals and intercostals (between the ribs) relax and lengthen. The image below highlights the chest muscles (pectoralis major and minor) and the abdominals for clarity.

As you can see Red Light Reflex can contribute to a myriad of complaints. The good news is it is relatively straight forward to release and relax all the muscles of the Red Light Reflex using safe simple Somatic Exercises or through Clinical Hands On Lessons. Through Somatics you will learn how to recreate these Reflexes voluntarily so that you can DECREATE them voluntarily. We do this by pandiculating all the muscles and movement patterns involved in each reflex (Green Light, Red Light and Trauma). This allows YOUR BRAIN to regain control of your muscles, and in turn your body and movement. If you would like to learn more, you can try an online class with me here.
