The patient is positioned in supine. The leg is placed in a figure-4 position (hip flexed and abducted with the lateral ankle resting on the contralateral thigh proximal to the knee.
While stabilizing the opposite side of the pelvis at the anterior superior iliac spine, an external rotation, abduction and posterior force is then lightly applied to the ipsilateral knee until the end range of motion is achieved. A further few small-amplitude oscillations can be applied to check for pain provocation at the end range of motion.
A positive test is one that reproduces the patient's pain or limits their range of movement.
Quadrant test
The patient is positioned in supine on the plinth.
The therapist stands on the side of the leg to be tested. The affected limb is placed in adduction and a compression force is applied and maintained through the femur through a range of 70-140 degrees of hip flexion. The test is repeated in abduction. A positive test is a reproduction of the pain.
