Efficacy of Diclofenac Sodium Shock Wave Phonophoresis on Patients With Subacromial Impingement Syndrome

Efficacy of Diclofenac Sodium Shock Wave Phonophoresis on Patients With Subacromial Impingement Syndrome: A Randomized Controlled Trial

The goal of the study is to determine the effect of radial shock wave Phonophoresis on patients with impingement syndromes. to answer the following questions:

does shock wave Phonophoresis have and effect on pain? does shock wave Phonophoresis have and effect on shoulder function? does shock wave Phonophoresis have and effect on subacromial space? patients will be randomized to two groups: Group (A): patients will receive shock wave Phonophoresis plus conventional physical therapy.

Group (B): Patients will receive shock wave plus conventional Physical therapy.
