About

The investigator assumed that perturbed-event-induced vibrotactile cueing enable more precision arm movement adjustment, sensory function and dexterity improvement in the spastic arm. Thus the specific aim of the study was to develop a vibrotactile therapy system that can provide vibrotactile feedback through the pinch performance of the hand when countering mechanically induced perturbations and also analyzed training effects of the perturbation-based pinch task training system on the sensorimotor performance of the hands for stroke patients.
