 For stabilization exercise, a supervised exercise program was employed for each patient. The exercises included posterior pelvic tilts, sit-ups, bridging, quadruped exercises, and posterior hip and knee muscles stretching 23. Not all patients could do all the exercise at a stretch; exercises were done according to the levels of tolerance and endurance of each patient. Patients were instructed to perform two to three stretches of all muscles per treatment and hold the stretch for 20 seconds unless it hurts. Strengthening exercises started with five repetitions and progressed according to each patients improvement, to three sets of 10 repetitions 10.
