Biofeedback boosts back pain therapy in new study
NCT ID NCT06613620
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether adding surface electromyographic biofeedback (a device that shows muscle activity on a screen) to standard stretching and strengthening exercises helps people with lower crossed syndrome—a condition involving muscle imbalances, lower back pain, and poor posture. Forty-six adults aged 19–35 with moderate pain received either standard therapy or standard therapy plus biofeedback for 4 weeks. Researchers measured changes in pain, disability, posture, and joint position sense.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- surface electromyographic biofeedback
- What this could lead to
- If it works, this could point toward a more effective physical therapy approach for lower crossed syndrome, reducing pain and improving posture.
- What could go wrong
- This is a small, completed trial with only 46 participants, so results may not apply to everyone. The biofeedback device adds complexity and cost without guaranteed extra benefit.
