The purpose of this study was to investigate the effect of foot orthotic on postural sway. Subjects were 15 patients(7 men and 8 women) who prescribed foot orthotic at B hospital and L rehabilitation medicine clinic in Seoul. Postural sway during a single limb stance was measured using the CMS 10 Measuring System when subjects positioned on the balance trainer under two treatment conditions(orthotic and nonorthotic). RCSP(resting calcaneal stance position) while subjects were standing on the glass plate was measured using the angle finder after subjects were positioned in prone to divide equally lower leg and calcaneus using the goniometer. The result was as follows. There were significant difference between postural sway of orthotic and nonorthotic conditions(t=4.888, 4.589, p<0.001), and the leg of the small RCSP within a subject has the small postural sway index(x^2=26.000, p<0.001). In conclusion, foot orthotics provide structural support for detecting and controlling postural sway in patients prescribed foot orthotics.
