Pectoralis Major (Clavicular Head) (Pec Clav R)

The M. Pectoralis Major Pars Clavicularis (Pectoralis Major (Clavicular Head)) is a muscle of the shoulder region. It is responsible for anteversion, adduction, internal rotation at shoulder joint. 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).
