Does interferential current provide additional benefit to orthopedic rehabilitation for the patients with proximal humeral fractures? A randomized controlled study.

研究概要

Thirty-five patients with non-displaced or minimally displaced proximal humeral fractures were randomized to receive interferential current (IFC) therapy plus orthopedic rehabilitation (n=18) or sham IFC plus rehabilitation (n=17). The primary outcome of interest was the Constant-Murley Score (CMS) for shoulder function. Secondary outcomes included the Visual Analog Scale (VAS) for activity pain, Disabilities of the Arm, Shoulder, and Hand (DASH) score, and paracetamol use. Outcomes were assessed immediately post-treatment and at 6 and 18 weeks post-treatment. Overall, the results revealed significant improvements in both groups for all outcomes over time, but no significant differences between the IFC and sham groups. The findings suggest that IFC does not provide additional benefit to standard rehabilitation for shoulder function and disability in these patients.
