Uncontrolled or slow movement is a problem with muscle tone, usually in the large muscle groups. The problem leads to slow, uncontrollable jerky movements of the head, limbs, trunk, or neck.
The abnormal movement may be reduced or disappear during sleep. Emotional stress makes it worse.
Abnormal and sometimes strange postures may occur because of these movements.
