Is this trial a fit for you?

Likely a good fit

Adults 20–50 with chronic non-specific low back pain (≥12 weeks) and confirmed hamstring tightness.

Probably not a fit

Those with spinal surgery history, radiculopathy, red flag symptoms, recent steroid injections, or contraindications to dry needling may not experience benefit.

What this trial studies

This randomized trial compares two physical therapy approaches—post-facilitation stretch and dry needling—added to conventional care in adults with chronic nonspecific low back pain and hamstring tightness. Thirty-six participants, aged 20–50, will be assigned to one of the two interventions for three weeks (three sessions per week) at the Spine Care Physical Therapy and Rehabilitation Centre in Peshawar. Outcomes include hamstring flexibility, pain, lumbar range of motion, pelvic tilt, and functional status, measured with standardized tests such as the Active Knee Extension Test. The study uses purposive sampling with sealed envelope randomization to allocate participants. All participants must meet eligibility criteria and have no contraindications to dry needling or other exclusions noted by the protocol.

Why it matters

Potential benefit: If successful, the trial could help identify which therapy more effectively improves flexibility, pain, and function for people with chronic low back pain and hamstring tightness.

How similar studies have gone: Prior research has explored dry needling and stretching separately; this trial investigates their direct comparison in a targeted CLBP population.
