Clinical effectiveness of high induction electromagnetic stimulation in patients with subacromial impingement syndrome: A single-blinded randomized controlled trial

BackgroundHigh Induction Electromagnetic Stimulation (HIES) is a new treatment modality. The clinical effectiveness of HIES applied in addition to conservative treatment in patients with Subacromial Impingement Syndrome (SIS) is unclear.ObjectiveTo examine the effects of HIES, applied in addition to conservative treatment on symptoms, functions, and activities of daily life in patients with SIS.MethodsA total of 36 participants diagnosed with SIS were included in the single- blinded randomized controlled study. The Visual Analog Scale (VAS) for pain intensity, the Disabilities of the Arm, Shoulder, and Hand Questionnaire (DASH) for upper extremity physical function, and the Constant-Murley Score (CMS) for the level of disability were used. The range of motion (ROM) measurements of the shoulder joint were performed using a goniometer. In the four-week rehabilitation program, one group (n = 19) received conservative treatment for 45 min, five days a week. The other group (n = 17) received HIES in addition to conservative treatment, applied in 10-min sessions with a one-day interval between sessions, for a total of 10 sessions.ResultsPost-treatment DASH score was found to be lower in the HIES group than in the conservative treatment group (p < 0.01). When the delta values obtained by subtracting the pre-treatment measurements from the post-treatment measurements were examined, the ΔVAS (p = 0.037) and ΔDASH (p < 0.01) values were significantly different between the two groups.ConclusionsHIES applied in addition to conservative treatment in patients diagnosed with SIS is more effective than conservative treatment alone in improving clinical outcomes and reducing pain.
