행군 시 발보장구 착용이 지면반력에 미치는 영향

Abstract

The purpose of this study was to examine the effects of customized foot orthotics during march in combat boots. Four volunteers with normal foot and six volunteers with excessive pronation foot among soldiers on service were fitted with foot orthotics. The Ground reaction forces signal from activity of Pre-After military marching. The marching was performed with a speed of 4.5 km/h. The experiment design for research wes composed two experimentation. The first experiment was to examine the ground reaction forces between normal foot and excessive pronator foot during march. The second experiment was to examine the ground reaction forces between wearing orthotics and no wearing orthotics. These data were analyzed by One-way ANOVA method and paired T-test method of SPSS(windows version 15.0). The result of the study were the maximum vertical impact peak and the maximum vertical loading rate on pronator foot tend to statistically significant increase after march. But the maximum vertical impact peak and the maximum vertical loading rate decrease the customized foot orthotics in volunteers with excessive pronation foot compared to volunteers with normal foot. Clinically, the application of orthotics for the soldiers with excessive pronation foot appears to keep nomal foot function and to decrease loading rate.
