Conclusion
This study aimed to investigate the effects of perturbation-based balance exercises performed using WBED on reactive postural control. The results showed that balance exercises using WBED decreased COP displacement during unexpected perturbation. Moreover, perturbation-based balance exercise using WBED improved reactive postural control function immediately. For fall prevention and the extension of a healthy livelihood, it is important to be able to perform perturbation-based balance exercises anywhere without instruments or medical expert guidance. Balance exercise using this device may help to reduce falls in older adults.
