An Efficacy Study of Exercise Rehabilitation on Pain and Disability for Patients With Non-specific Low Back Pain

Study Overview
=================
Brief Summary
-----------------
The primary objective of this study is to compare the efficacy of two different exercise programs for the reduction of pain and disability in a specific subgroup of NSLBP patients and aims to investigate the additive effect of hip stabilization exercises. The investigators hypothesize that the combined local (segmental) stabilizer and hip stabilizer program (T2) will be more effective in reducing pain and disability in NSLBP patients compared to the local (segmental) stabilizer program (T1).

Detailed Description
-----------------
The secondary objective of this study is to measure the changes in lumbopelvic and hip mechanics for both treatment groups following completion of the exercise programs. We hypothesize that there will be differences observed between groups following the 6wk rehabilitation programs, and that only the group completing the combined local (segmental) stabilizer and hip stabilizer strengthening program (T2) will demonstrate significant differences in mechanics compared to baseline testing.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in pain intensity measured by a 10cm visual analogue scale | Measures will be taken at baseline, at 3wk follow up, and at 6wk follow up to ivestigate the changes at mid point and following the exercise intervention | 6 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in biomechanical variables using an eight camera motion capture system | Measures will be taken at baseline and at 6wk follow up to ivestigate the changes at mid point and following the exercise intervention | 6 weeks | 
| Change in disability score as measured by the Oswestry Disability Questionnaire | Measures will be taken at baseline, at 3wk follow up, and at 6wk follow up to ivestigate the changes at mid point and following the exercise intervention | 6 weeks |
