Serratus Anterior (Serr Ant R)
The M. Serratus Anterior (Serratus Anterior) is a muscle of the shoulder region. It is responsible for protraction and upward rotation of scapula, stabilization against thorax. This muscle is not covered by the official SENIAM catalogue — placement is based on established clinical literature. This page documents the exact electrode position, anatomical attachments and a standardized test movement based on Hermens et al. (2000).
