  7. 7. Introduction  Stroke is the leading cause of long-term disability (Turney et al. 1984; American Heart Association 2005)  Hand dysfunction is the most common impairment post-stroke. (Butefisch et al. 2003; Lang and Schieber 2003)  Lack of finger independency or muscle selectivity is a primary contributor (Li et al. 2003; Lang & Schieber 2003, 2004)  … A strategy to reduce abnormal coupling?  Muscle vibration affects the motor-evoked potential (MEP) of the vibrated muscle in healthy and possibly stroke individuals. (Siggelkow et al. 1999; Rosenkranz and Rothwell 2003; Yang et al. 2006). biome chanics & me dical application lab Bing-Shiang Yang , Ph.D., P.E. National Chiao Tung University, Taiwan
  8. 8. Aim 1  Identify the patterns of muscle vibration-modulated hand corticomotor excitability in individuals following stroke (Yang et al., 2006) biome chanics & me dical application lab Bing-Shiang Yang , Ph.D., P.E. National Chiao Tung University, Taiwan
  9. 9. Aim 2  Effect of MV on stretch reflex – The contribution of spinal pathways on vibration-induced changes in motor evoked potentials is not clear. + Brain Ia Inhibition =  Result: Spinal cord – The amplitude of M1 was Vibration Efferent depressed by vibration.

National Chiao Tung University, Taiwan
  10. 10. Aim 3  Examine whether the vibration-induced neurophysiological modulations reflect in the voluntary control of finger movements. Hypothesis  Muscle vibration to selective hand muscle affects muscle selectivity and finger independency in healthy/stroke individuals. biome chanics & me dical application lab Bing-Shiang Yang , Ph.D., P.E. National Chiao Tung University, Taiwan
  11. 11. Aim 4  Examine the effect of attended prolonged muscle vibration on hand corticomotor excitability and control of finger movements. Hypotheses:  prolong muscle vibration and subject’s attention to vibration provide long-lasting effect on hand corticomotor excitability.  the long-lasting modulations of motor pathway excitability also reflect on control of finger movements. biome chanics & me dical application lab Bing-Shiang Yang , Ph.D., P.E.
