Kinetic Symphony
I've written before about the structure/function thing in working with movement and use of self. My first exposure was on the Robert Schleip web site, though he is trained in both Rolf and Feldenkrais. I'm now discovering more. An article on walking by another Rolfer, Aline Newton, takes a very functional approach to walking and celebrates the work of Serge Gracovetsky. The thrust of Newton's and Gracovetsky's take on walking is that it doesn't just happen in the feet and legs. The spine is the key. In fact, Gracovetsky wrote a book called The Spinal Engine. I believe it is now, sadly, out of print. Here are some quotes from Newton's article:
The legs play an important role, but it is in providing fuel for the dynamic spine which is the true engine of locomotion.
From the arch of the toes to the sub-occipital joint, legs, pelvis, spine and arms work as one system in a great work of energy transformation that lets us walk with minimal energy expenditure. The bones and soft tissues are involved in an elegant interplay that has the potential to transmit the forces with optimum ease. Far from the image of a passive trunk carried by strong legs, in this model walking transforms into a kinetic symphony.
Force closure, how all the elements involved create a coordinated movement, can only be observed in a dynamic context.
