Post‑isometric relaxation versus post‑facilitation stretch for chronic low back pain

Effects of Post Isometric Relaxation Versus Post Facilitation Stretch Techniques on Pain, Mobility and Disability in Patients With Chronic Low Back Pain

Not applicable Interventional Riphah International University · NCT07026045

This project will try two manual muscle‑stretching techniques—post‑isometric relaxation and post‑facilitation stretch—along with standard physical therapy in adults 18–45 with chronic low back pain to see which reduces pain and disability more.

What this trial studies

This randomized controlled study will enroll 42 adults aged 18–45 with chronic low back pain at two Lahore clinics using convenient sampling and informed consent. Participants are randomized to receive either post‑isometric relaxation or post‑facilitation stretch in addition to standard physical therapy, with interventions delivered over four weeks. Primary outcomes are pain (Numeric Pain Rating Scale), lumbar mobility (inclinometer), and disability (Urdu Oswestry Disability Index) measured at baseline and after 4 weeks. Key exclusions include neurological signs, systemic musculoskeletal disease, recent abdominal or back surgery, pregnancy, and radiculopathy.

Who should consider this trial

Good fit: Adults 18–45 with chronic low back pain (>3 months), NPRS pain >3 to ≤7 and ODI 14–50%, without neurological findings or recent surgery, are the intended participants.

Not a fit: Patients with radiculopathy or other neurological symptoms, systemic soft tissue or bony disease, recent abdominal or back surgery, pregnancy, or outside the specified pain/disability ranges would likely not benefit or be eligible.

Why it matters

Potential benefit: If successful, adding one of these simple manual techniques to standard physical therapy could reduce pain and disability in adults with chronic low back pain.

How similar studies have performed: Previous small trials of manual techniques like post‑isometric relaxation and facilitation stretching have reported mixed but sometimes positive effects for low back pain, so this comparison builds on limited prior evidence.
