Purpose: To decrease pain within the quadratus lumborum and/or increase ROM

Procedure: With the patient lying in prone, stand on the contralateral side to be treated. Find the most tender point in the quadratus lumborum, then move the patient into sight hip flexion and external rotation until tenderness resolves. Maintain contact with the tender point in this position for 90 to 120 seconds, then slowly and passively return the patient to the starting position.
