Document Summary

All 4 sensory programs play a role in movement control: visual, auditory, vestibular, somatosensory, relative contribution depends on movement, environment, individual"s ability. Sensory info is required for both feedback & feedforward control. Movement control involves many areas of cns: ex: basal ganglia, cerebellum, spinal cord, brain stem, cerebral cortex, etc. Problems with 1 area of cns can influence control and require adaption in other areas. Feedforward control (open loop): movement control planned before execution: requires all sensory input & other necessary info to be available prior to movement, can be executed without sensory input, advantage: faster, disadvantage: (cid:315) accuracy, (cid:313) errors. Intrinsic (cid:314) how your movement feels/new body position: can be used to adjust the current movement, advantage: allows correction, adapts so it can be more accurate to requirements, disadvantage: slower. Movement is a combination of both feedforward & feedback control. Models: used for planning and prediction in movements to fix problems.
