Parts of the body that are most frequently involved are the muscles of the face, neck, shoulders, trunk and hands. Simple tics involve only 1 muscle group, as in eye blinking, shoulder shrugging or neck jerking, whereas complex ties may include multiple muscle groups and cause more complex motions.
