Electrical muscular stimulation on shoulder instability: is it beneficial?

This paper explores the potential benefits of Electrical Muscular Stimulation (EMS) in managing shoulder instability. The review synthesizes evidence from multiple medical databases without time restrictions, focusing on the role of EMS in enhancing physical therapy outcomes. Findings highlight that patients with posterior shoulder instability who received NMES-enhanced therapy demonstrated significantly reduced instability episodes and subluxation, particularly with position-triggered stimulation. The study concludes that EMS can provide clinically meaningful improvements, with position-triggered ES showing superior effectiveness compared to passive stimulation, especially in conditions like poststroke shoulder subluxation.
