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 patients legs as proximal to the patients crotch. A force is applied to patients superior leg to move it downwardly from a resting position. During downward movement of the patients superior leg, the bolster functions as a fulcrum and the patients superior femur functions as a lever arm to create a first class lever that partially distracts the femoral head from the acetabulum. After application of the force, the resiliency of the bolster causes the patients superior leg to return to the resting position. The movements may be repeated, and the degree of hip flexion and rotation may be varied to affect different regions of the hip capsule.
