Background Subacromial impingement syndrome (SIS) is defined as the mechanical compression of subacromial structures between the coraco-acromial arch and the humerus during active elevation of the arm above shoulder height.

Objectives The aim of the study was to investigate the effects of applications of iontophoresis and phonophoresis, which has been used in addition to physiotherapy program on pain and disability level in patients with SIS.

Methods The study was conducted with subjects (n=43) diagnosed with SIS. The subjects were divided into two groups randomly as iontophoresis group (IG) and phonophoresis group (PG). Diclofenac sodium iontophoresis was applied to the first group (n=22), diclofenac sodium phonophoresis was applied to the second group (n=21). In addition all of groups therapy program includes superficial heat, transcutaneous electrical nerve stimulation and exercise. The groups were evaluated before and after treatment in terms of pain and scores of shoulder disability. Visual analog scale was used to assess of pain (night pain, rest pain, pain with motion and pain in functional use), Shoulder Disability Questionnaire (SDQ) and Disabilities of the Arm Shoulder and Hand (DASH) were used to assess of shoulder disability.

Results 43 patients with IS aged 18 to 65 years were recruited to the study. Demographic data were similar in the groups.

After treatments pain severity (night pain and pain in functional use) was significantly decreased in both groups (p<0,05) and in the scores of disability of shoulder (p<0,05) in both groups. Pain relief was similar in groups. SDQ and DASH scores were improved in two groups after treatments. But there was no difference between the groups in terms of functionality and disability scores.

Conclusions This study shows that diclofenac sodium iontophoresis and phonophorosis that are used in patients with subacromial impingement syndrome have similar positive therapeutic effects on shoulder functions.
