Interventions

  • Post Isometric Relaxation — PROCEDURE
    Participants allocated to this arm will receive Post Isometric Relaxation. Each participant will undergo 6 sessions over 2 weeks (3 Sessions/week), and receive Conventional Physiotherapy
  • Active Isolated Stretching — PROCEDURE
    Participants allocated to this arm will receive Active Isolated Stretching. Each participant will undergo 6 sessions over 2 weeks (3 Sessions/week), and receive Conventional Physiotherapy.

Study Details

The purpose of this study is to evaluate the comparative effects of post-isometric relaxation (PIR) and active isolated stretch (AIS) techniques on reducing pain, improving range of motion, and decreasing functional disability in individuals with piriformis syndrome. A total of 40 participants will be recruited, aged 20-55 yrs, with confirmed piriformis syndrome. Participants will be randomized into two equal groups. Group A (post isometric relaxation) and Group B (active isolated stretch). Both groups will receive Conventional Therapy (Thermotherapy, Electrotherapy). Study variables include: * Independent Variable: Post Isometric Relaxation and Active Isolated Stretching. * Dependent Variables: Pain (measured by Visual Analog Scale), Functional Disability (assessed via Oswestry Disability Index), Range of Motion (assessed via Goniometer). * Control Variables: Age, Gender, BMI, Baseline Pain/ Disability Scores/ROM The intervention will last 2 weeks with 6 sessions (3 sessions per week). Assessments will be conducted at baseline (Week 1, Pre-treatment) and Post every second session. Data will be analyzed to compare immediate and short-term effects of the two interventions. This study aims to provide evidence for targeted manual therapy approaches in priformis syndrome, potentially guiding clinicians toward the most effective technique for pain reduction, improve ROM and decrease functional disability.
