Shock waves zapped stiff muscles in small trial
NCT ID NCT06934668
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a treatment called extracorporeal shock wave therapy (ESWT) can reduce stiffness in the upper back muscle (trapezius). Researchers used a special ultrasound technique to measure muscle stiffness before and after treatment. The study involved 40 healthy adults aged 18 to 45. The goal was to better understand if ESWT works for muscle stiffness, not to treat a disease.
