Hypothesis: Differentiation May Unstick the Fascia

Differentiation may unstick the fascia.

Each muscle is wrapped in something like translucent saran wrap so that muscles which move in the same general direction can still glide against one another. 'Moving in unison' is not the same thing as 'glued stuck.' When fascia loses its glide — through underuse, injury, chronic tension, or simply the slow drift of habit — the muscles that share a fascial neighborhood start to get recruited together even when they don't need to be.

The variations in a Feldenkrais lesson that differentiate commonly-grouped muscles may help restore that glide. By asking one muscle to do something different from its neighbor, you create a small mechanical shearing force between them — just enough to remind the fascia that these are separate structures capable of independent motion.
