Summary

This trial investigates whether adding hamstring stretching to traditional exercises improves flexibility and function in people with nonspecific low back pain lasting at least 12 weeks. Forty-six adults with limited hamstring flexibility will be randomly assigned to either stretching plus exercises or exercises alone. Researchers will measure changes in flexibility and disability over the study period.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: hamstring stretching plus traditional exercises
What this could lead to: If stretching helps, it could offer a simple, low-cost addition to standard care for chronic low back pain.
What could go wrong: This is a small, early-stage trial with only 46 participants, so results may not apply widely. Stretching alone is unlikely to be a complete solution for complex back pain.
