Comparative Effects of Muscle Energy Technique and Routine Physical Therapy on Quadratus Lumborum in Patients With Chronic Low Back Pain

Comparative Effects of Muscle Energy Technique and Routine Physical Therapy on Quadratus Lumborum in Patients With Chronic Low Back Pain: A Randomized Controlled Trial

•Null hypothesis: There is no difference in effects of Muscle Energy Technique and Routine Physical Therapy on Quadratus Lumborum in patients with chronic low back pain.

•Alternative hypothesis: There is difference in effects of Muscle Energy Technique and Routine Physical Therapy on Quadratus Lumborum in patients with chronic low back pain.

Study Overview

• Status: Completed
• Conditions: Chronic Low-back Pain
• Intervention / Treatment: Other: Routine Physical Therapy; Other: Muscle Energy Technique

Detailed Description

The purpose of the study is to compare the effects of Muscle Energy Technique and Routine Physical Therapy on Quadratus Lumborum in patients with chronic low back pain on Pain, Range of Motion, Quality of Life and Functional Disability.

The study procedure will be explained to the patients and informed written consent will be obtained from those patients who will be willing to participate in the study. Quadratus Lumborum tightness will be assessed using side bending test.

Those fulfilling the requirement of inclusion criteria will be indiscriminately separated into 2 groups. NPRS, Oswestry Disability Index, SF-20 and goniometer will be used to collect data.

Total 68 participants will be recruited in the study. Routine Physical therapy will be provided to group A. Reciprocal inhibition Muscle Energy Technique on quadratus lumborum along with Routine Physical Therapy will be performed on group B.

Both group will receive interventions three sessions in a week for 4 consecutive weeks.

Assessment of Pain, Range of motion, Quality of Life and Functional Disability will be assessed by using goniometer, NPRS, Oswestry Disability Index and SF-20 Questionnaire respectively for both groups at the baseline, end of 6th session (2nd week) and end of 12th session (4th week) and follow up will be obtained after 1 month (8th week).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Routine Physical Therapy group; Routine physical therapy group includes thermotherapy for 10 mins, transcutaneous electrical nerve stimulations for 10 mins. Exercises such as: Pelvic tilts, bridging exercise, William flexion exercises and stretching will be performed for 7-10 repetitions. Treatment duration will be 25 minutes.	Other: Routine Physical Therapy; Routine physical therapy will be provided to group A for 25 minutes thrice a week for 4 weeks.; Other Names: Conventional Physical Therapy
Experimental: Experimental group; Experimental group includes 6-7 repetitions of Muscle energy technique on Quadratus Lumborum muscle and Routine physical therapy, i.e Thermotherapy, transcutaneous electrical nerve stimulations, Pelvic tilts, bridging exercise, William flexion exercises and stretching will be performed for 7-10 repetitions. Treatment duration will be 40 minutes.	Other: Muscle Energy Technique; Muscle Energy technique along with Routine physical therapy will be provided to group B for40 minutes thrice a week for 4 weeks.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pain will be assessed by Numeric pain rating scale	Pain will be measured using 11 point Numeric Pain rating scale (NPRS). 0 score represents no pain, 1-3 score represents mild pain, 4-6 represents moderate pain and 7-10 represents severe pain.	1 minute
Range of Motion will be assessed by Universal Goniometer	Lumbar flexion, extension and side bending range of motion will be measured using Universal Goniometer. Normal lumbar flexion range is 60 degrees, extension range is 25 degrees, and right and left side bending range is 25 degrees.	2 minutes
Quality of life will be assessed by Medical outcomes study: 20 item Short form survey instrument	The SF-20 measure contains three dimensions about function (physical, social and role) and well-being (mental health, health perception and pain). score between 75- 100 leveled as good quality of life of low back pain patients, Average QOL marked when QOL score between 50-74, and QOL score between 0-49 leveled as poor QOL.	8 minutes
Functional Disability will be assessed by Oswestry Low Back Pain Disability Index	Oswestry disability index is a validated, 10-point patient-reported outcome questionnaire. • 0% to 20% is scored as minimal disability. • 21%-40% is scored as moderate disability. • 41%-60% is scored as severe disability. • 61%-80% is scored as crippled. • 81%-100% scored as bedbound patients.	5 minutes
