Figure 1a. Experimental set-up for the Step task.

Figure 1a

Monitor showing the template was placed in front of the subject. Electromyograms (EMGs) from nine muscles of the shoulder, elbow and wrist of the right side were collected (not shown in figure). The subject pushed forward (pulled backward) on the handle, resulting in a positive (negative) moment of force about the x-axis of force transducer-1. The x-axis of the transducer is indicated by the dashed line.
