Mechanical Diagnosis and Therapy approach to assessment and treatment of derangement of the sacro-iliac joint

This case report describes the clinical reasoning and management of the sacroiliac joint, utilising the McKenzie Method of Mechanical Diagnosis and Therapy (MDT). A patient with a 2 year history of buttock and thigh pain demonstrates a directional preference for repeated anterior SIJ rotation. The MDT approach is discussed and is an ideal method for emphasising the patients involvement in managing their own back problem.
