Summary

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.

• Stroke Rehabilitation

Interventions

Type	Name	Description
OTHER	Vibratory perturbed task-specific movement training	The perturbation-based pinch task training was conducted with the affected hand placed on the pinch device. The horizontal vibratory perturbation was generated for a total of 20 minutes by two recoil-type actuators with a frequency of 30 Hz and an amplitude of 2 mm, and intermittent exposure (10 s per 30 s). Each training session was divided into eight cycles with a training interval of 2 min per 2.5 min.
OTHER	Traditional task-oriented facilitation	Reach-to-grasp training and hand release training
OTHER	Sensorimotor training	Targeted to goals that are relevant to the sensorimotor facilitation of the patient
