Can Hands-On spine pressure loosen back muscles?
NCT ID NCT07826260
First seen Sep 17, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
Researchers at the University of Primorska are testing whether a hands-on physiotherapy technique called Maitland Grade III++ central posteroanterior mobilization changes the stiffness of back muscles in healthy adults. About 25 participants aged 21 to 38 without low back pain will each receive the real mobilization and a sham gentle pressure in random order. The team measures erector spinae and multifidus muscle stiffness with shear wave elastography and myotonometry right before and after each session.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Maitland Grade III++ central posteroanterior lumbar mobilization, a hands-on physiotherapy technique using rhythmic pressure on the lower spine
- What this could lead to
- If it works, this could help physiotherapists understand whether hands-on lumbar mobilization changes muscle stiffness, which may inform how manual therapy is used for back issues.
- What could go wrong
- This is a small, early study in healthy adults without back pain, so any stiffness changes may be temporary and may not apply to people with low back pain. Manual mobilization can cause mild soreness or discomfort.
