Abstract: A method for mobilizing a hip joint capsule of a patient using a resilient bolster. In accordance with the method, the patient assumes a lateral position, with the hip capsule to be treated superior. The resilient bolster is placed between the patient's legs as proximal to the patient's crotch. A force is applied to patient's superior leg to move it downwardly from a resting position.
