EMS for Post-Stroke Shoulder Pain: Insights from Recent Swiss Published Research

A 2025 systematic review examined eight clinical trials involving 341 stroke survivors with hemiplegic shoulder pain. Researchers measured pain intensity using validated scales such as the Visual Analogue Scale and Numerical Rating Scale. Combined results showed that low-frequency electrical stimulation, commonly known as EMS, significantly reduced pain scores (SMD = −0.68, p = 0.006). These findings suggest EMS may help ease post-stroke shoulder pain. The study was led by scientists from Chengdu University of Traditional Chinese Medicine and published in the peer-reviewed journal Frontiers in Neurology.
