Purpose: The purpose of this study was to investigate the effects of whole-body vibration stimulation on proprioception and tactile in patients with spastic cerebral palsy.
Methods: This study was conducted on 9 children diagnosed with spastic cerebral palsy. Of the single case study methods, the ABAB design was employed in this study. Out of a 12-week study period, three weeks were allocated to each of two baseline periods and two intervention periods. The exercise was performed twice a week for 30 minutes. A general trunk stabilization exercise was performed during the baseline period and a trunk stabilization exercise accompanied with whole-body vibration was performed during the intervention period. Evaluation was performed five times in total: before the experiment, after baseline 1, after intervention 1, after baseline 2, and after intervention 2. To determine the effect of the exercise method, a skin sensory evaluation tool (monofilament kit) and a trunk proprioception sensor (digital dual inclinometer) were used. To compare the effects of the exercises at baseline and after intervention, an analysis of variance on repeated measures (repeated ANOVA) was performed to analyze the data.
Results: The results showed that there were statistically significant increases from baseline in the means of proprioception and tactile during the intervention period with whole-body vibration (p <.05).
Conclusion: Whole-body vibration can be proposed as an effective intervention method for improving the proprioception and tactile in children with spastic cerebral palsy, and this exercise method is expected to be actively used in clinical practice.
