The Influence of the Difference of Platforms on Postural Stability During Standing

Objective: The aim of this research is to determine the influence of the difference of platforms on postural stability during standing for an adult target. Method: This research was conducted on 30 adult students from H University in Gangwon Province from April 2010 to July 2010. 3 different platforms were tested. Measurement tools used were the Tetrax Interactive Balance System to determine static balance, 7-item BBS-3P and the Functional Reach Test to determine dynamic balance. To determine the change in balance according to platform, ANOVA was used. Scheffe was used to determine the similarities in the 3 platforms. Results: The softer the platform, the smaller the static balance and dynamic balance (p<.05>). Blocking of vision also showed a decrease in static balance (p<.05>). The firm platform showed a larger decrease in dynamic balance compared to static balance, whereas soft platform showed a larger decrease in static balance over dynamic balance. Conclusion: This study reveals that high hardness is favorable to achieve safety. In the case that static balance is important, a soft platform should be selected. In the case that dynamic balance is important, a firm platform should be selected.
