Abstract

The present study was conducted to examine how the movement strategy of Functional Reach Test (FRT) affects the results of Functional Reach Distance (FR distance) and displacement of center of gravity. Nineteen normal subjects aged 21.6±4.3 years performed FRT in three conditions; 1) hip-FRT where a subject kept foot joint in a neutral position without restrictions in hip joint when reaching, 2) foot-FRT where a subject kept hip joint in a neutral position without restrictions in foot joint, and 3) heels-up-FRT where a subject kept heels up without restrictions in hip joint. In each FRT, FR distance, anterior-posterior displacement of center of gravity, and sway area were measured. FR distance in order of length were heels-up-FRT, hip-FRT and foot-FRT, and each difference was significant (p≤0.05). Anterior-posterior displacement and sway area were significantly greater in heels-up-FRT than hip-FRT and foot-FRT (p≤0.01). Correlations among FR distance, anterior-posterior displacement and sway area were nonsignificant. Analysis of major components among variables revealed a high contribution rate of a component which reflected anterior-posterior displacement (30.7%), and of a component which divided FR distance from anterior-posterior displacement (25.4%). Heels-up-FRT resulted in a greater anterior-posterior displacement and a larger sway area, and required higher postural control ability. In case of the same FRT condition, there was no significant correlation between FR distance and displacement of center of gravity.
