Effects of Back Muscles Endurance Training in Patients With Chronic Mechanical Low Back Pain

Riphah International University28 enrolled

Overview

Low back pain is one the leading cause of disability and affecting many individuals. Chronic low back pain is associated with restriction in daily physical activities that ultimately leads to disuse atrophy of muscles. The objective of the study is to find out the effects of Back Muscles Endurance Training on pain, disability, endurance and Lumbar flexibility in patients with chronic mechanical low back pain.

Low back pain is the leading worldwide cause of years lost to disability and its burden is growing alongside the increasing and ageing population. Mechanical low back pain refers to back pain that arises intrinsically from the spine, intervertebral disks, or surrounding soft tissues. Repetitive trauma and overuse are common causes of chronic mechanical low back pain, which is often secondary to workplace injury. Most patients who experience activity-limiting low back pain go on to have recurrent episodes. Low back pain is a common condition affecting many individuals at some point in their lives. Chronic low back pain prevalence increases linearly from the third decade of life on, until the 60 years of age, being more prevalent in women.

Conditions

Mechanical Low Back Pain Paraspinal Muscles Muscle Stretching Exercises

Interventions

Muscle endurance training (MET)OTHER

Experimental group will be given MET Program, stretching \& strengthening exercises and Hot packs (for 15 minutes). MET program will include warm up, endurance and cool down exercises. The warm up and cool down period will be consisted of 5-minute walking, and 10 repetitions of stretching exercises. Endurance exercises will consist of 4 levels.

Conventional TreatmentOTHER

Conventional treatment group will be given hot packs (for 15 minutes) and Strengthening \& stretching exercise program including: STRETCHING EXERCISES (lumbar extensor muscles, iliopsoas muscles, hamstring muscles, gastrocnemius muscles and pectoral muscles). STRENGTHENING EXERCISES (rectus abdominus crunch, oblique crunch, pelvic elevation, single leg pelvic elevation, lumbal spine extension, on hands and knees position with the raise of one leg, on hands and knees position with the raise of opposite arm and leg). Each exercise will be repeated 10 times.

Outcomes

Primary Outcomes

NUMERIC PAIN RATING SCALE

NPRS is anchored by terms describing pain severity extremes. The 11-point numeric with 0 representing No pain, 1-3 representing Mild Pain (nagging, annoying, interfering little with ADLs), 4-6 representing Moderate Pains (interferes significantly with ADLs), 7-10 representing Sever Pain (disabling, unable to perform ADLs)

Time frame: 6 weeks

REVISED OSWESTERY DISABILITY INDEX (RODQ)

The Oswestry Disability Index (also known as the Oswestry Low Back Pain Disability Questionnaire) is an extremely important tool that researchers and disability evaluators use to measure a patient's permanent functional disability. The test is considered the 'gold standard' of low back functional outcome tools. This scale contain question related to functional activities of pain intensity, personal care, lifting, walking, sitting, standing, sleeping, sex life, social life and travelling. For patients understanding, URDU version is used.

Time frame: 6 weeks

PRONE DOUBLE STRAIGHT-LEG RAISE TEST

The prone double straight-leg raise test will be used to assess participants' back muscle endurance. The participant lay on the plinth in prone-lying position, hips extended, with the hands underneath the forehead and the arms perpendicular to the body. Instruct the participant to raise both legs until knee clearance is achieved. The researcher will monitoring knee clearance by sliding one hand under the thighs. The time taken by participant to maintain knee clearance monitored with a stopwatch will be recorded in seconds as back muscle endurance

Time frame: 6 weeks

MODIFIED SCHOBER'S TEST

The patient is standing with his back towards the examiner. The examiner determines the location of the lumbosacral junction at the level of the posterior superior iliac spine by pressing the location of the dimples of Venus. The intersection of the top of the dimples of Venus is marked by drawing a horizontal line. This line acts as the landmark. Two other marks will be drawn 10 cm above and 5 cm below the first landmark. The patient will then be asked to bend over and touch his or her toes as long as possible without increasing pain. The examiner will measure the increase in distance between the superior and inferior marks. The length increment, which is the difference between the 15-cm distance (neutral position) and the increased distance (anterior flexion posture), will be calculated to determine the range of motion of the lumbar spine
