Effect of Remote Subthreshold Noise on Hand Function Post-Stroke Marcella Kosmopoulos, Dr. Pilwon Hur, Dr. Na Jin Seo Stroke survivors have reduced grip function due not only to motor deficit but also to sensory deficit in the hand. Remote vibrotactile noise has been shown to enhance tactile sensation for stroke survivors with sensory deficit [Enders el al, 2013]. The effect of vibrotactile noise on enhancing hand grip function in stroke survivors, however, is unknown. Objective: Evaluate the effectiveness of the remote subthreshold vibrotactile noise in improving hand function for stroke survivors with sensorimotor deficit. Enders et al., J Neruoeng Rehabil,10:105, 2013
Hand function was compared with vs. without remote subthreshold vibrotactile noise in four blocks of testing • Vibrotactile noise was set at 60% of the threshold Dorsal side • Four blocks of testing • Four hand function tasks and two sensory tests were performed in each block Volar side The Box and Block Test (BBT) The Nine Hole Peg Test (NHPT) Maximum Pinch Grip and Control
The performance of three hand function tasks were improved with the remote subthreshold vibrotactile noise • Potential to develop an assistive rehabilitation device • The remote effect positions the vibrotactiles so it will not interfere with object manipulation and dexterous hand function
