Q

What usually happens to the fascia that precedes deformity of osseus and cartilaginous structures in chronic disease?

A

It accomodates to chronic stress patterns and deforms itself (Wolff’s law)

Q

What is a gentle requirement if a viscous drag and resistance are to be avoided when attempting to produce a change in, or release of, restricted fascial structures, and why?

A

A gentle touch.

Because resistance in colloids increases proportionally to the velocity of force applied to them (fascia = colloid)

Q

After applying pressure to an area which has had it’s gel dehydrated contracted and hardened, the removal of the pressure allows the system to rapidly re-gel. The ground substance becomes more porous, a better medium for the diffusion of…..?

A

Nutrients, oxygen, waste products of metabolism and the enzymes and building blocks involved in the ‘metabolic regeneration process’

Q

Because of immobility, new fiber connections will behave in what manner?
