[Purpose] The objective of this study was to investigate the effects of whole-body vibration (WBV) in the horizontal direction on the motor function and balance of chronic stroke survivors. [Subjects and Methods] This study was a randomized controlled trial. Twenty-one individuals with chronic stroke from an inpatient rehabilitation center participated in the study. The participants were allocated to either the WBV training group or the control group. The WBV training group (n = 12) received whole-body vibration delivered in the horizontal direction (15 min/day, 3 times/week, 6 wks) followed by conventional rehabilitation (30 min/day, 5 times/week, 6 wks); the control group (n = 9) received conventional rehabilitation only (30 min/day, 5 times/week, 6 wks). Motor function was measured by using the Fugl-Meyer assessment, and balance was measured by using the Berg Balance Scale (BBS) and the Timed Up and Go (TUG) test before and after the interventions. [Results] After the interventions, all variables improved significantly compared with the baseline values in the WBV training group. In the control group, no significant improvements in any variables were noted. In addition, the BBS score in the WBV training group increased significantly compared with that in the control group. [Conclusion] WBV training with whole-body vibration delivered in the horizontal direction may be a potential intervention for improvement of motor function and balance in patients who previously experienced a stroke.
