| Research Abstract |
We proposed and have been developing a passive motion exercise device which enables passive dorsiflexion/plantarfrexion movements of ankle with adjustable inversion/eversion. This research project aimed to examine the effects of dampers attached to the passive mechanical joint around inversion/eversion axis of the device. The project also aimed to find indicators of the effect of exercise motion through experiments with healthy subjects.
We have conducted preliminary experiment on the effect of the dampers employed on the inversion/eversion axis. In the experiment, small pneumatic dampers were attached to the footplate of the prototype device. The results show that the dampers attached to the passive mechanical joint will avoid the rapid motion of the footplate that may cause undesirable reaction of the patients. In order to find indicators that represent effects of the exercise motion, we conducted experiments with healthy subjects and biosignals were obtained during exercise motion as well as before and after exercise motion. Among measured biosignals, skin blood flow and surface/deep tissue temperature showed patterns of variation which may be related to exercise motion. We also modified the prototype device to make it more adjustable to the users.
