Shock wave gel could ease shoulder pain without needles
NCT ID NCT07657637
First seen Jun 20, 2026 · Last updated Jun 20, 2026
Summary
This study tests whether combining a pain-relief gel (diclofenac) with sound waves (shock wave phonophoresis) can reduce pain and improve shoulder function in people with subacromial impingement syndrome. Seventy adults aged 25–40 with shoulder pain will be split into two groups: one gets the gel plus shock waves and physical therapy, the other gets shock waves and physical therapy alone. The goal is to see if the added gel makes a difference in pain, function, and shoulder space.
