Fig. 4From: Comparison between sEMG and force as control interfaces to support planar arm movements in adults with Duchenne: a feasibility studyMeasurement path to obtain a two-dimensional stiffness force field. Graphical representation of the path made by the robot across the participant’s workspace (dashed square) and used to obtain a two-dimensional stiffness force field. This measurement data is used to actively compensate arm stiffness forces when using the force-based control with stiffness compensation (FSC) methodBack to article page
