| Outline of Final Research Achievements |
On the subject of grip adjustment, we investigated the conditions for which anticipating tactile stimulation effectively facilitates human reactive actions. Furthermore, the same or similar principles were attempted to apply for avoidance behavior against fall by stumbling.
The anticipating tactile stimuli facilitated the prehension correction when the reactive increase in grip force begins 100 ms or longer after the commencement of perturbative force to the handle. In contrast, the tactile stimuli exhibited little influence on reactive motion for the rapid perturbation to the handle.
We also conducted walking trials on a treadmill while restricting ankle motions with taping. Certain indices presented that the subjects were more at risk of falling. Some modifications of experimental conditions remain to be studied before we test the function of anticipating tactile stimuli.
