Post-isometric relaxation for lower back muscle pain
Part of Pain clinical trials.
This study tests whether a stretching technique called post-isometric relaxation can help people with quadratus lumborum syndrome—a condition causing lower back and side pain. The technique involves gently contracting and then relaxing a specific back muscle to reduce pain and improve function.
Summary written for real people, not researchers, by Clin2.

- Your back pain has lasted 12 weeks or less (not chronic)
- You do not have numbness, tingling, or radiating pain into your buttocks or legs
- You do not have spine conditions like disc herniation, spondylolisthesis, or spondylosis
