title: Physiology of abnormal movements.
abstract: The units of the central nervous system controlling voluntary movement are described and the roles of the motor and sensory cortex, of the basal ganglia and cerebellum and of the final common loop are outlined. The pathophysiology underlying disturbances of movement, power and tone of the limbs is discussed, with particular reference to the more common dyskinesias.
