Document Summary
Motor disorders: hyperkinetic, hypokinetic, high movement, dystonia, choria, tremor, huntington(cid:495)s, reduced movement, parkinsonism, movement disorders: disorders of the neuromuscular system that affect the ability to produce and control movement. Movement control requires control of posture: 2. Movement is controlled by feedforward and feedback mechanisms: 3. Control from many systems and levels within the central nervous system (cns) Postural control in movement: movements often have a clear purpose, e. g. pick up a glass, take a step, some muscles contribute directly to the purpose, postural muscles are also required to control, body position, stability. Motor program: feedforward control requires all necessary information to be available prior to movement, generalized motor program, representation of a type of movements in the cns, 1. Invariant features are consistent across class of movement and represented in cns: vary by movement, common invariant elements include, relative timing of actions, relative force of muscles, sequence of actions, 2.
