Massage guns vs. manual therapy: which eases shoulder pain better?

This trial compares two hands-on therapies—percussion massage with a handheld device and instrument-assisted soft tissue mobilization—when added to standard physiotherapy for people with shoulder impingement syndrome. About 48 adults aged 40–60 with confirmed impingement will be randomly assigned to one of three groups: physiotherapy alone, physiotherapy plus percussion massage, or physiotherapy plus instrument-assisted therapy. Over four weeks, researchers will measure changes in shoulder joint position sense, range of motion, pain, disability, and quality of life to see if the added therapies improve outcomes.
