traction response, the body’s reaction to traction applied to the spine. Alterations of certain signs and symptoms of a musculoskeletal disorder may be revealed by traction tests. For example, if traction relieves a symptom, it may indicate impingement of a nerve root. Traction also may be used therapeutically to increase joint range, overcome muscle spasms, shorten soft tissues, or neutralize pressure and relieve pain in various joints.
