Tensegrity Causes Headaches


More and more healers, trained in Alexander Technique, Pilates, Rolfing, or Chiropractic, are preaching tensegrity as the way to comprehend the holistic nature of the human body. It is one of my ongoing delights to observe this way of thinking propagate messily throughout the blogosphere. Alex J. P. Boylan from Manchester, England recently posted a nice piece on headache care, and used the metaphor in a mixed way.

Is your headache really a pain in the bum?

Our bodies are always striving to stay in balanace, in fact our structural body IS in fact always in balance, or we wouldn’t be able to stand up without falling over. That doesn’t mean that we are always problem or pain-free however. The human body is what is reffered to as a tensegrity model, which basically means that any force acting on one part of the body is transfered to some degree to every other part. Within this model, there are certain structures which have relationship and effect each other greatly in keeping this balance.

But Boylan then contradicts this message with a traditional story of the stacked-up-spine.

At the base of your spine there is a wedge shaped bone call your sacrum, upon which the whole spine is stacked all the way up to your skull. The part of the skull which is at the base at the back is a bone called the occiput. The sacrum and the occiput basically have a very close inter-relationship which means that they mirror each others movement, and if one shifts in any direction the other will eventually move to keep the all important gravitational balance.
Maybe Alex J.P. Boylan BSc (Hons) MBAcC retreated from the metaphor to keep his reader engaged. Or maybe he his comprehension of tensegrity ends at a vague notion of holism, and does not extend to the idea of the myofascial network as a comprehension tension net that both integrates the body's tensegrity and propagates mechanobiological messages throughout the epi-hormonal system. Either way, his prose is proof that all the Skwishes sold to date, and all the Anatomy Trains workshops that have been held, are getting through to the general public, one strut at a time.
