Document Summary
The pre-structured set of movement commands that defines and shapes the movement: they are representations of movement that are stored in memory, these form the plan (program) for the movement. When the cns gets altered in a way so that the brain does not receive afferent signals: nerve bundles are cut at the spinal cord, the motor pathways are still in tact. A surgical procedure where afferent sensory pathways are cut: this prevents nerve impulses from reaching the spinal cord, this prevents the use of feedback in closed-loop control. Gross motor skills remain functional: e. g. Simple, fast and gross movements can still be performed. Motor program controls movement until feedback can otherwise have an effect. Gross motor skills remain functional: patients without sensory feedback from the legs can still position their knee at specific angles. Fine motor skills are hindered: touching their thumb with their fingers.
