Can releasing a deep back muscle ease pain and help you breathe better?
NCT ID NCT06928792
First seen Sep 10, 2026 · Last updated Sep 11, 2026 · Updated 1 time
Summary
Researchers test whether a muscle energy technique that releases the quadratus lumborum, a deep muscle in the lower back, improves breathing and reduces pain in people with chronic low back pain. The trial enrolls 36 adults aged 30 to 60 who have had mechanical low back pain for more than three months and show signs of a tight quadratus lumborum. Half receive the muscle release plus standard exercises, and half receive standard exercises alone. The team measures pain, lung function, chest expansion, fatigue, and spine flexibility over six months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- muscle energy technique on the quadratus lumborum muscle, plus standard back pain exercises
- What this could lead to
- If it works, this could offer a low-cost, drug-free way to ease low back pain and improve breathing for people with chronic back pain.
- What could go wrong
- The trial is small, with 36 participants, and the muscle energy technique may not add clear benefit beyond standard exercises. Results may not apply to other back pain types or older adults.
