Document Summary
Postural control- the maintenance of body alignment and spatial orientation in order to put the body in a position to enable effective movement. Muscle tone- the force with which the muscle resists lengthening. Serves to: maintain a base level of postural control, regulate the storage and release of elastic energy, regulate force dampening. Postural tone- background level of activity, baseline level necessary for function during rest and activity. Tone dependent on: 1) viscoelasticity of the muscle and tendon elastic elements (passive tone, ie hydration, 2) level of neural activation of the contractile elements (active tone, reflexive) Postural control- maintains body alignment (self) and spatial orientation (environment) Stability- primary outcome of alignment and orientation, a position that is resistant to disturbance or returns to its normal state after disruption. 3 parts: whole body stability- orients body to prevent or prepare for falls (aka balance)
