Electric needle therapy eases calf injury pain?

This study looked at whether a treatment called percutaneous electrolysis (using a tiny electric current through a needle) can help people with calf muscle tears feel better and move more easily. About 75 adults with a torn medial gastrocnemius muscle were split into three groups: one got a strong current, one a weak current, and one a fake treatment. Researchers measured pain, fear of movement, ankle flexibility, and muscle fatigue before and after treatment to see if the real treatment worked better than the fake one.
