Comparing two treatments for tight hamstrings in chronic lower back pain

This trial is testing whether dry needling or soft tissue mobilization—two different hands-on treatments—works better for relieving tight hamstrings in people who have had lower back pain for at least 6 months. Both groups will also receive standard physical therapy exercises. The study will help doctors understand which approach is more effective for your specific type of pain.

Many people with chronic lower back pain also have tight hamstrings, which can make the pain worse and limit movement. Researchers want to know which hands-on treatment—dry needling or soft tissue mobilization—helps patients recover better when combined with standard therapy.
