Middle Deltoid (Delt Med R)
The M. Deltoideus Pars Acromialis (Middle Deltoid) is a muscle of the shoulder region. It is responsible for abduction at shoulder joint (from 15 degrees). This muscle is one of 26 with official SENIAM-recommended surface EMG electrode placement. This page documents the exact electrode position, anatomical attachments and a standardized test movement based on Hermens et al. (2000).
Abduction at shoulder joint (from 15 degrees)
Greatest curvature of the muscle
Orientation: Toward acromion–lateral epicondyle

Based on SENIAM recommendations (Hermens et al. 2000). Not an official SENIAM product. See all references \u2192
Raise arm laterally (abduction 90 degrees) against resistance
Common use cases for surface EMG measurement of the M. Deltoideus Pars Acromialis:
Greatest curvature of the muscle. Orientation: Toward acromion–lateral epicondyle. Based on the official SENIAM recommendations (Hermens et al. 2000).
Raise arm laterally (abduction 90 degrees) against resistance. This movement is part of the SENIAM protocol for standardized contraction verification.
Yes. The M. Deltoideus Pars Acromialis is one of 26 muscles for which the SENIAM project has published official surface EMG electrode placement recommendations.
