Fig. 4From: Coupling of shoulder joint torques in individuals with chronic stroke mirrors controls, with additional non-load-dependent negative effects in a combined-torque taskModeled dual-task strength. Solid lines are simulated maximal joint torques using OpenSim setup with similar posture to the prescribed protocol. Experimental data overlayed with mean (± standard error). (Top) Females; (Middle) Males; (Bottom) All data normalized to maximum humeral rotation torque (external or internal). Background co-activation limits of 10 and 20% were added to simulate hypertoniaBack to article page
