The interaction force and end-effector distance during ACE. (a) The average interaction force and end-effector distance of healthy subjects and (b) that of the hemiplegic patient. F: the interaction force; D: the distance; AC: active circle tracking task with constraint; AL: active line tracking task with constraint; ACNC: active circle tracking task with no constraint; ALNC: active line tracking task with no constraint.
