Effects of Post Isometric Relaxation in Patients With Quadratus Lumborum Syndrome
Sponsor: Riphah International University
Summary
The most common musculoskeletal problem in both developed and developing countries is low back pain. Quadratus lumborum syndrome is a common source of low back pain, defined as a myofascial pain syndrome characterized by pain due to spasm and stiffness of the quadratus lumborum muscle. This condition often occurs when weak back muscles are compensated by the quadratus lumborum, leading to painful muscle spasms. This study aims to determine the effects of PIR on pain, muscle endurance, and disability in patients with Quadratus Lumborum Syndrome.

Interventions
Conventional Traetment
Maitland MobilizationPosterior-Anterior Glide will be performed on the transverse processes of the L1 to L4 vertebrae. The amplitude will initially be grade 1 and 2 for pain relief, and grade 3 and 4 will be used to improve ROM, with slow speed, smooth rhythm, and 2 to 3 oscillations per second for 30 seconds. There will be 2 to 3 sets for each vertebra
Post-Isometric Relaxation (PIR)
The practitioner stands behind the side lying patient, at waist level. The patient has the uppermost arm extended over the head to firmly grasp the top end of the table and, on an inhalation, abducts the uppermost leg until the practitioner palpates strong quadratus activity (elevation of around 30° usually). The patient holds the leg isometrically in this manner, allowing gravity to provide resistance for 10-second, the patient allows the leg to hang slightly behind him over the back of the table. The practitioner straddles this and, cradling the pelvis with both hands (fingers interlocked over crest of pelvis), leans back to take out all slack and to ease the pelvis away from the lower ribs during an exhalation. The stretch should be held for between 10 and 30 seconds. Contraction followed by stretch is repeated with raised leg in front of, behind the trunk in order to activate different fibers and was given bilaterally
