My guiding principle: Pain is intelligent and intentional – Part 4.

How you think about pain will determine how you treat it. Embody this principle and it will improve your efficiency and your treatment outcomes. Part 4 interacts with some of the science to explain perhaps why what we do works.

What is the mechanism?

Lets conclude this little series of articles by discussing the mechanism. Many years ago I grew convinced through my clinical experience that fascia (somehow) mediates pain, biomechanical restrictions and retards proprioception. To my delight, the more I read the latest research the more this hypothesis seems to have support.

What are the scientists saying?

The young and fertile field of functional anatomy and fascial mechanics is fascinating. Only a handful of years ago the International Fascia Congress was inaugurated. This conference brings body workers and scientists together. The scientists present their latest research and the practitioners present their clinical observations. The content shared at this conference provides some of the best theories and evidence based research into the anatomy and function of the fascia. The book Fascia – The Tensional Network of the Human Body (Schleip, Findley, Chaitow, Huijing) is a compilation of several of the papers presented at these conferences and is a brilliant asset. I refer to it often.

Fascia – Wow, this stuff is rich.

Fascia, that substance that has historically been viewed as a benign connective substance that ‘just holds stuff together’, is gradually gaining recognition as our ‘most important perceptual organ’ (Schleip 2003). Langevin (2006) stated ‘It is likely that the connective tissue continuum of fasciae and fascial structures serves as a body-wide mechanosensitive signalling system with an integrating function analogous to that of the nervous system.’

Other scientists have found that compared with the skeletal muscle system, the interconnected fascial network not only has a much greater surface area than skeletal muscle, skin or any other body tissue but it is also innervated by approximately six times as many sensory nerves as the skeletal muscle system.

The myriad of tiny unmyelinated proprioceptive and free nerve endings are found almost everywhere in the fascial tissues providing proprioception (movement and coordination feedback) and very likely nociception (pain feedback). Little experiments have demonstrated that joint fixations traditionally thought to be due to fascial ‘adhesions’ only released by force would in fact ‘relax’ under anaesthetic. This suggests that the fascia is not a lifeless adhesive ‘scar tissue’ type substance but is, at least in part, connected to the nervous system, able to relax and contract in some respect.

As a result ‘…today an increasing number of practitioners are basing their concepts to some extent on the mechanosensory nature of the fascial net and its assumed ability to respond to skilful stimulation of its various sensory receptors….’

Most of the sensory nerves in fascia are near the surface.

Now it gets really exciting for you as a body therapist. Immediately underneath the skin, epidermis and dermis is an enveloping layer of dense and areolar connective tissue and fat called the ‘superficial fascia.’ Marwan Abu-Hijleh et. al. explain that not only does this subcutaneous tissue (fascia) connect the skin to the underlying deep, dense fascia which invest muscles and aponeurosis throughout the body (1) but other scientists explain that this layer appears to be endowed with an exceptionally rich density of proprioceptive nerve endings (2). In other words, the ‘thinking’, highly responsive fascia is literally just under the skin.

Manipulate the fascia, not the muscle!

I am convinced through my clinical experience that fascia (somehow) mediates intelligent and deliberate biomechanical restrictions, pain and retards proprioception.

I am convinced that when I perform a deliberate and specific cross-fibre manipulation that creates tension / friction between the skin and the underlying muscle or bone, I am stimulating the fascial system rather than directly ‘loosening muscle’. 

This thinking has radically influenced the way I work, and my clinical results seem to back it up.

I am not pushing on muscle to ‘soften or stretch’ the muscle. I am not mechanically repositioning tendons. I am stimulating the fascia which in turn communicates (again, somehow) to the skeletal muscle to relax or lengthen. I am stimulating the fascia which in turn responds by ‘switching off’ the local tenderness. I am stimulating fascia which in turn restores proprioception.

If this is true then the clinical implications are huge . . .

If this is true then we may find that specific and brief manipulation to the fascia may communicate to a muscle to ‘release’ and lengthen eliminating the need to ‘massage the muscle loose’. If this is true then we may find that less is more; that time following a brief manipulation, giving the fascia opportunity to respond, may be more valuable than constant massage for 30 minutes.

I do believe that pain, and for that matter restricted movement and proprioceptive retardation, are intelligent messengers wired into the body designed to activate intentionally and as such can be ‘switched off’ and I believe that the fascial network may just be the anatomy of the body that somehow mediates these effects.

So really, this is not the end of the conversation but just the beginning.
