The purpose of this study was to evaluate of balance performance and to examine the
relationship between balance performance and feet position, platform speed. Twenty two
subjects(men 8, women 14, mean age 24.45 years) performed nine balance test with eyes
closed for 25 seconds: 3 feet position(feet together, feet 12cm in apart, feet 24cm in
apart) and 3 platform speed(100%, 70%, 40%).
The results were as follows:
1. There are significant difference between center of balance and feet position(p<0.05).
2. There are no significant difference between center of balance and plaform
speed(p<0.05).
3. There are significant difference between sway index and feet position(p<0.05).
4. There are significant difference between sway index and plaform speed(p<0.05).
