PURPOSE: The aim of this study was to compare the effect of whole body vibration stimulation on ankle instability, ankle range of motion, and balance ability in adult with chronic ankle instability.
METHODS: Forty-five adult with chronic ankle instability were randomly equally allocated theIgroup (whole body vibration stimulated at 10 Hz), or the II group (20 Hz), or the III group (25 Hz). All the participants (male:13/female: 32, age: 26.64±3.14) in this study received whole body vibration therapy for an additional 15 minutes after hot pack and ultrasound three times a week for four weeks. Outcome were measured before and after 4 weeks training.
RESULTS: All the three groups showed significant differences in AII and CAIT after intervention (p<.05). I group showed the most significant difference (p<.05). All the three groups also showed significant increase in ankle dorsiflexion and plantar flexion after training (p<.05). I group showed greater increase than the other groups in ankle dorsiflexion (p<.05). The X-axis, Y-axis, and fluctuation speed were significantly decreased in the three groups (p<.05), but there was no significant difference between the three groups after the intervention.
CONCLUSION: The findings suggest that the whole body vibration stimulation according to various frequencies is effective for improve ankle instability, ankle range of motion and balance ability in adult with chronic ankle instability. 10 Hz whole body vibration stimulation could help improve ankle instability and ankle range more effectively than other frequencies.
