surface electromyography

Surface electromyography (sEMG) is a technique used to measure the electrical signals generated by muscles when they contract. By placing small sensors on the skin over a muscle, sEMG can record the muscle’s activity level and timing during movement or rest. This information helps in diagnosing muscle disorders, improving athletic training, and guiding physical therapy. The signals are typically very small and require specialized equipment to interpret. Overall, sEMG provides a non-invasive way to understand how muscles work, aiding both clinical assessment and performance optimization.
