Effects of Hamstring Stretching Using Pressure Biofeedback Unit in Patients With Low Back Pain.

Study Overview
=================
Brief Summary
-----------------
To determine the effects of Hamstring stretching using a pressure Biofeedback unit on muscle length, pain, and functional status in patients with low back pain.

Detailed Description
-----------------
Several studies have been conducted regarding hamstring stretching with the pelvis anteriorly tilted for treating low back pain but there is very little evidence regarding the use of a pressure biofeedback unit for maintaining anterior pelvic tilt so this study aims to find out whether the hamstring stretching while maintaining anterior pelvic tilt using pressure biofeedback is more effective than hamstring stretching without using pressure biofeedback in patients with low back pain.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Hamstring Length | Changes from baseline, Hamstring length was measured through Goniometer. Normal value of Active knee extension is 90 degree with 90 degree hip flexion. Values less than 70 degree knee extension represents hamstring tightness. | 12 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain through NPRS | Changes from baseline, Pain was measured through Numeric pain rating scale. 0 represents no pain and 10 worst pain possible. | 12 days | 
| Functional Status | Changes from baseline, Functional status was measured through Oswestry Disability Index. 0-20 shows minimal disability, 21-40 moderate disability, 41-60 severe disability, 61-80 crippled and 81-100 bed bound patients. | 12 days |
