Fig. 1From: Changes in muscle coordination patterns induced by exposure to a viscous force fieldExperimental setup and feedback system. Subjects sat on a chair in front of an LCD screen, grasping a 2-degrees-of-freedom semi-active joystick with their right hand. The direction of motion (y) was always parallel to the subject’s sagittal plane. During the experiment, EMG data of 10 surface muscles of the right upper limb were recorded. The subjects received video, audio, and force feedbackBack to article page
