From: Contributions of the Individual Muscles of the Shoulder to Glenohumeral Joint Stability During Abduction J Biomech Eng. 2008;130(2):021024-021024-9. doi:10.1115/1.2903422 Figure Legend: Comparison of muscle activations predicted by the model (black lines) and measured EMG (gray lines) for seven muscles crossing the shoulder. Pectoralis major represents the clavicular portion of the muscle. The EMG data were normalized by the level corresponding to a maximum voluntary contraction (MVC). The thick gray lines are the means of the EMG data averaged over six subjects; the thin gray lines represent ±1 standard deviation.
