A case of a pathogenic active scar.

Soft tissues follow every movement of bones and joints. Their free movement is essential for normal functioning of the motor system. Scars form mainly in the soft tissues, and if abnormal, or 'active', can interfere with the function of the motor system as well. For diagnosis and treatment the barrier phenomenon is a most useful concept: a pathological barrier restricts movement and does not spring when engaged. After engaging the barrier and waiting, release, relief and normal mobility are obtained. An illustrative case with an active appendectomy scar is presented, with both low back and abdominal pain. Extensive and costly examination were all negative. After diagnosis and treatment of the active scar symptoms were promptly relieved. Diagnosis and treatment of active scars should become part of the physical therapist's approach to the patient's problems.
