| Abstract |
Objective
To assess the static balance under the virtual moving surround (VMS) in healthy young and elderly adults.
Method
There were twenty four healthy young adults and thirty nine healthy elderly aged 60 and older. Each group was tested with forceplate during quite standing with eyes opened, closed and under the VMS for static balance. The VMS was stimulated with a head-mounted display (HMD). The parameters for static balance were total sway path distance and area.
Results
All static balance parameters of healthy elderly were significantly increased in all conditions when comparedwith parameters of young adults. In the young adults and elderly, total sway path distance and sway area were significantly different under the VMS. In the healthy elderly, total sway path distance and sway area were significantly increased under the VMS as much as eyes closed .
Conclusion
In the healthy adults, the VMS could provoke the significant postural sway during static standing. VMS can be used as a tool to evaluate and treat of the patients with static balance dysfunction. (J Korean Acad Rehab Med 2006; 30: 254-260) |
