Abstract

The aim of this study was to estimate the immediate effects of plantar vibration, applied to the more affected foot, on balance impairment in patients post-stroke. This pretest-posttest clinical study included 18 pa-tients (13 men) poststroke; mean age 56.0±8.9 years (range, 41-71 years). One session of 5-min vibratory stimuli (frequency, 100 Hz) was applied to the plantar region of the more affected foot of all participants. The plantar vibration significantly improved the Timed UP and Go test (P=0.03, Cohen d=0.15), ankle plantar flexor muscle spasticity (P=0.008), and ankle passive range of motion (P < 0.001, Cohen d=0.74). The posturography measures and Functional Reach Test did not im-prove significantly (P > 0.05). Vibration stimuli applied to the plantar re-gion of the more affected foot had significant effects on spasticity, ankle passive range of motion and dynamic balance as evaluated by the Timed Up and Go test in patients poststroke. There was no effect on static balance performance. Based on the results, the focal vibratory stimuli applied directly to the plantar region of the more affected foot may be recommended to improve the functional mobility and dynamic balance in patients with stroke. © 2018 Korean Society of Exercise Rehabilitation.
