Comparing hydrocortisone phonophoresis and iontophoresis for shoulder impingement

Effect Of Hydrocortisone Phonophoresis Versus Iontophoresis In Patients With Subacromial Impingement Syndrome

Not applicable Interventional Horus University · NCT05919121

This study tests whether using hydrocortisone with phonophoresis or iontophoresis can help people with shoulder impingement feel better and move their shoulder more easily after other treatments haven't worked.

What this trial studies

This study aims to evaluate the effectiveness of hydrocortisone phonophoresis versus iontophoresis in treating patients with subacromial impingement syndrome (SIS). Participants will undergo therapeutic exercises combined with either phonophoresis or iontophoresis to assess improvements in pain, function, range of motion, and shoulder strength. The study focuses on patients who have not responded adequately to conservative treatments and have specific clinical signs of SIS. By comparing these two methods, the study seeks to identify the most effective approach for managing this condition.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-60 diagnosed with unilateral stage II subacromial impingement syndrome who have not responded to conservative NSAID treatment.

Not a fit: Patients with conditions such as frozen shoulder, arthritis, or previous shoulder surgeries may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for patients suffering from subacromial impingement syndrome.

How similar studies have performed: While there is ongoing research in the management of shoulder pain, this specific comparison of hydrocortisone phonophoresis and iontophoresis is relatively novel.
