Stronger back muscles may ease chronic pain — a trial puts the idea to the test
NCT ID NCT07719452
First seen Jul 22, 2026 · Last updated Jul 23, 2026 · Updated 1 time
Summary
This trial investigates whether adding specific lumbar extension strengthening exercises to standard physical therapy (manual therapy and motor control exercises) can further reduce disability and improve back muscle function in adults with chronic low back pain. Sixty participants will receive eight weeks of physical therapy, with half also doing targeted low back strengthening. Researchers will measure changes in disability, muscle thickness, endurance, and healthcare use to see if the extra exercises make a meaningful difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- lumbar extension strengthening exercises added to standard physical therapy (manual therapy and motor control exercises)
- What this could lead to
- If adding these exercises proves effective, it could lead to a more targeted physical therapy approach for chronic low back pain, potentially reducing disability and reliance on other healthcare.
- What could go wrong
- This is a relatively small, early-stage trial (60 participants) comparing two non-drug treatments. The added exercises may not provide significant extra benefit over standard therapy alone, and results may not apply to all back pain patients.
