Can sling exercises rewire back pain? trial tests muscle control in sciatica
NCT ID NCT06558383
First seen Sep 16, 2026 · Last updated Sep 17, 2026 · Updated 1 time
Summary
Researchers at Cairo University are studying whether a specific exercise program that targets the posterior oblique sling, a network of muscles in the lower back and pelvis, can improve muscle coordination and function in people with lumbosacral radiculopathy. This condition causes leg pain from a pinched nerve in the lower spine. The trial enrolls 40 adults with chronic L5/S1 disc herniation and moderate to severe leg pain. Participants receive either the sling activation program or a standard physical therapy program, both for 18 sessions over six weeks. The study measures muscle activity, pelvic motion, pain thresholds, and disability to see if the targeted exercises lead to better outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a targeted exercise program that activates the posterior oblique sling, a group of muscles connecting the back, pelvis, and leg
- What this could lead to
- If it works, this could offer a non-drug way to improve movement and reduce disability for people with nerve-related low back and leg pain.
- What could go wrong
- The trial is small and early, so results may not hold for everyone. Exercise programs can cause temporary soreness, and some participants may not improve.
