Published September 12, 2026, in PM&R, this review examines surface electromyography, or EMG, as a rehabilitation tool.
Making activity visible Surface electrodes detect muscle activation and provide immediate feedback. The authors describe applications that help people recognize weak-muscle recruitment or unwanted co-contraction during therapeutic practice.
Why it matters Feedback can make an otherwise hard-to-observe process easier to discuss and practice with a clinician. The review also considers barriers to routine use.
How to read the evidence This is a review, not a new treatment trial. The abstract supplies no pooled benefit estimate, condition-specific evidence grades or safety synthesis. Muscle EMG does not measure brain activity directly.
