Lumbar Thrust-mobilization Effects on Hip Strength and Anterior Knee Pain

The intervention group will receive passive spinal rotational grade V thrust-mobilization, based on Maitland's approach. The intervention will be performed with the subject in right sidelying and left sidelying. The operator's palpating hand is placed over the L2-3 intervertebral space, and the other hand bends both legs of the participant up to the range at which the L2-3 midposition is found. The participant is then asked to straighten the lower leg and hook the upper leg over it with the upper leg's knee positioned over the side of the plinth. While the lower component is kept still, the participant's trunk is rotated until the hip starts to lift off from the plinth. The bottom hand and uppermost hand rest under a pillow and the chest wall, respectively. With the starting position settled, the operator stands behind the participant, takes up the slack within the spine and then provides a grade V thrust- mobilization while stabilizing the uppermost shoulder.

Subjects are positioned in right sidelying. The experimenter holds both knees with one arm while placing their opposite hand on the participant's lumbar spine. The experimenter performs 1 min of flexion and extension passive range of motion without reaching physiological end range in either direction of movement. This is repeated with the subject in left sidelying.
