Effects of Post Isometric Relaxation Compared to Active Isolated Stretch on Pain, Movement, and Disability in People with Piriformis Syndrome

What this Trial Is About

Researchers are evaluating the effects of two manual therapy techniques, post-isometric relaxation PIR and active isolated stretch AIS, on pain, range of motion, and functional disability in people with piriformis syndrome. This randomized controlled trial will enroll 40 participants aged 20 to 55 years with confirmed piriformis syndrome, aiming to guide clinicians toward the most effective approach for symptom relief and improved mobility. Participants will be randomly divided into two groups Group A will receive post-isometric relaxation therapy, which involves isometric muscle contractions followed by relaxation phases, and Group B will receive active isolated stretching, involving active limb movement with therapist-applied stretches. Both groups will also receive conventional physiotherapy including thermotherapy and electrotherapy. The intervention lasts two weeks with six sessions total, scheduled three times per week. Participants will undergo assessments before treatment and after every second session, measuring pain using the Visual Analog Scale, functional disability via the Oswestry Disability Index, and range of motion with a goniometer. Data will be compared within and between groups to evaluate immediate and short-term effects of each therapy. The study includes baseline and post-intervention evaluations to track changes over the two-week period.
