(A) Comparison of peak resultant joint contact force location within the glenoid rim for computational models with individualized muscle forces (solid markers) and computational models using the muscle forces from the nominal model (hollow markers). (B) Simulations with the nominal model using subject-specific kinematics have peak joint contact forces located closer to the center of the glenoid rim. (C) The ratio of the superior-inferior and medial-lateral components of the peak joint contact force was calculated for simulation results with individualized models (gray bars). Mean (solid line), SD (dashed line) of cohort ratio values are shown. CM02, RF01, and RM01 had peak joint contact forces located near or outside the glenoid rim (panel A) and also had ratio values exceeding 1SD of the cohort values (hashed bars, panel B), with results from analyses with generic models (black bars, panel B) within 1SD of cohort values.
