Infraspinatus (Infra R)
The M. Infraspinatus (Infraspinatus) is a muscle of the shoulder region. It is responsible for external rotation at shoulder joint, stabilization of humeral head (rotator cuff). 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).
