Effect of Clamshell Exercise on Lumbopelvic Stability and Low Back Pain in Post Partum Women

Study Overview
=================
Brief Summary
-----------------
This study will be conducted on 44 females with postpartum LBP & pelvic instability, selected from Dar of women hospital in port said to investigate effect of clamshell exercise on lumbo-pelvic stability and low back pain in postpartum women.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: control group<br>Abdominal bracing | Other: Abdominal bracing<br>* they will perform 3 times/week of static abdominal contraction for six weeks.<br>|
| Active Comparator: study group<br>Abdominal bracing and clamshell exercise | Other: Abdominal bracing<br>* they will perform 3 times/week of static abdominal contraction for six weeks.<br>Other: clamshell exercise<br>* Each women will be positioned in side lying on the floor, with the pelvis and the spine in neutral position, the hips will bent at 45° and the knees flexed to 90°. She will abduct the top knee as far as possible, while keeping the heels together, then return to the starting position , the position will be maintained for 5 seconds in an abduction state, and repeated 10 times, with rest for 1 minute to minimize muscle fatigue,they will perform 3 times/week fo 6 weeks<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in the degree of lumbopelvic instability | Change in the degree of lumbopelvic instability will be measured by specific tests(The dip test, the runner pose test and the single leg squat test) and the pateint performance will be graded as poor or good | change in the lumbopelvic instability degree will be measured at baseline and after 6 weeks of the interventions | 
| lumbopelvic range of motion | Degree of lumbopelvic range of motion will be measured by goniometer | change in the lumbopelvic instability degree will be measured at baseline and after 6 weeks of the interventions | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| severity of pain intensity | change in low back pain intensity will be measured using visual analogue scale(VAS) low back pain intensity | change in the lumbopelvic instability will be measured at baseline and after 6 weeks of the interventions | 
| the degree of function disability | the change in the degree of function disability will be measured by Oswestry disability index (ODI) | change in the lumbopelvic instability will be measured at baseline and after 6 weeks of the interventions |
