Purpose The present study was to investigate to extent that effects of sensory information distortion by muscle vibration on continuous limb movement in aging and accuracy constraint Methods Young adult group (n=11) and older adult group (n=11) were divided. All participant were instructed to perform repetitive aiming movement to specified targets under three-accuracy constraints (i.e., low, high, and mixed accuracy constraints) in the vibration and no-vibration conditions. Kinematic data was collected by movement time and movement error frequence Results The results showed that compared with young adult, older adult increased movement time when accuracy constraint was high under vibration condition. Older adult also was a high degree of movement errors than young adults when accuracy constraint was high under vibration condition Conclusion The muscle vibration stimulation may influence considerably on the continuous limb movement probably due to degeneration in sensory information processing by aging.
