Shock wave combo may ease shoulder pain without surgery

This study looks at whether adding a special shock wave treatment (called phonophoresis) to standard physical therapy can help people with shoulder impingement syndrome. The goal is to see if it reduces pain, improves shoulder function, and increases space in the shoulder joint. About 70 adults aged 25 to 40 with shoulder pain will be randomly assigned to receive either shock wave phonophoresis plus physical therapy or shock wave alone plus physical therapy.
