M. Brachialis

Brachialis (Brachi L)

The M. Brachialis (Brachialis) is a muscle of the upper arm region. It is responsible for elbow flexion (strongest elbow flexor, independent of pronation/supination). 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).
