Effects of Post Isometric Relaxation in Patients With Quadratus Lumborum Syndrome

Starting soon · Not applicable

Conditions studied: Quadratus Lumborum

In brief

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.
