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

Not Applicable

• Conditions: Low Back Pain
• Interventions: Other: Hamstring stretching with Pressure Biofeedback Unit; Other: Hamstring stretching with out Pressure Biofeedback Unit

• Registration Number: NCT05059496
• Lead Sponsor: Riphah International University

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.

Arm && Interventions

Group	Intervention	Description
Hamstring stretching with Pressure Biofeedback Unit	Hamstring stretching with Pressure Biofeedback Unit	Hot pack, Hamstring stretching with Biofeedback unit, TENS
Hamstring stretching with out Pressure Biofeedback Unit	Hamstring stretching with out Pressure Biofeedback Unit	Hot pack, Hamstring stretching without Biofeedback unit, TENS

Primary Outcome Measures

Name	Time	Method
Hamstring Length	12 days	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.

Secondary Outcome Measures

Name	Time	Method
Functional Status	12 days	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".
Pain through NPRS	12 days	Changes from baseline, Pain was measured through Numeric pain rating scale. 0 represents "no pain" and 10 "worst pain possible".
