Outline of Final Research Achievements

The aim of this study was to investigate the optimal noise type and intensity which was added into the galvanic vestibular stimulation (GVS) for improving the upright standing sway in stroke patients. In addition, the effect of short term noisy GVS approach for improving the postural sway was also investigated in stroke patients. For healthy and stroke subjects, the optimal noise was a white noise with strong noise power (0dBW) and stimulus intensity was 70 % of sensory threshold level of each subjects. In stroke patients, the noisy GVS approach was effective for improving postural sway at after the intervention term, but not sustained that effect for next term.
