It will include 18 postpartum women who will receive back care advice and postural correction exercises.

It will include 18 postpartum women who will receive the same back care advice and postural correction exercises, in addition to retro-walking.

All patients in both groups will be advised to use proper lifting techniques, avoid prolonged sitting or standing, maintain a healthy weight, quit smoking, practice good posture, take breaks, spread housekeeping duties over the whole week, and sleep in supportive positions.

It will be used to measure the severity of post cesarean low back pain before and after the treatment program for all participants in both groups. The VAS is ten cm horizontal line on which the patients' pain intensity is represented by a point between the extremes of no pain at all (no pain=0) and worst pain imaginable (worst pain=10). Each participating woman will be asked to put a mark on the line at the point indicating her pain level / intensity.

It will be assessed by the Modified Schober test before and after the treatment program for all participants in both groups. The therapist will mark the lumbar spine at the posterior superior iliac spines, with another mark 15 cm above it. A tape measure will be used to record the distance between the marks in a standing position, then again after the patient bends forward into full lumbar flexion. The difference indicates the lumbar flexion ROM. This test will be repeated three times, and the average value will be taken as the lumbar flexion ROM.

It will be assessed by the Modified Schober test before and after the treatment program for all participants in both groups. The therapist will mark the lumbar spine at the posterior superior iliac spines, then place another mark 15 cm above. A tape measure will record the distance between the marks while the patient is standing. The patient will then bend backward into full lumbar extension, and the new distance between the marks will be measured. The difference represents the lumbar extension ROM. This process will be repeated three times, with the average value taken as the lumbar extension ROM.

It will be used to assess functional disability for all women in both groups before and after the end of the treatment program. The Oswestry disability questionnaire is considered the "gold standard" tool for low back functional outcome It is consisted of 50 questions covering 10 sections (personal care, lifting, sitting, standing, walking, sex life, sleeping, social life and travelling). Each question is scored from 0-5, giving maximum score of 50 if one section is missed, the total score will be 45 and then the score is converted into percentage. scores are classified according to severity into minimal disability (10-20%), moderate disability (21-40%), sever disability (41-60%) crippled (61-80%) and bed bound (81-100%).
