Fig. 8From: Effect of two types of shoulder prosthesis on the muscle forces using a generic multibody model for different arm motionsOpenSim® shoulder model used for the estimation of the contribution of the friction on the total moment around the gleno-humeral joint and the prosthesis COR, respectively. The axis around which the moment is calculated for abduction is shown with dash-dotted line, the arm is in horizontal position (90°).Back to article page
