Simple motor tics are typically sudden, brief, meaningless movements that usually involve only one group of muscles, such as eye blinking, head jerking, or shoulder shrugging.

The lifter stands erect, hands about shoulder width apart, and slowly raises the shoulders as high as possible, and then slowly lowers them, while not bending the elbows, or moving the body at all.
