Definition - What does Rotation mean?
Rotation is an anatomical term of motion that describes the turning of a body part along its long axis. Rotation may be further classified as medial or lateral, pronation, or supination. Job duties that require repetitive rotation of body parts, particularly in awkward positions or under load, increase the risk of work related musculoskeletal injuries.
WorkplaceTesting explains Rotation
Rotational movement includes any action that involves a twisting motion. Examples of rotation would be the turning of the leg out so that the toes point away from the body, or the twisting of the arm to change the direction of the palm.
The plane in which rotation is performed will determine how it is further defined. For instance, twisting the arm and hand is called supination or pronation. Medial rotation turns the body part toward the body's midline while lateral rotation turns the opposite way.
Repetitive motions that require rotation can cause stress on the joints and surrounding tissues causing musculoskeletal injuries.
