—A) Toe clearance and its components with and without ankle-foot orthosis (AFO) in the total study population; B) the severe ankle impairment group; and C) the mild ankle impairment group. The comparison in the total study population shows a significant increase in the component of limb-shortening and significant decrease in the component of hip elevation due to pelvic obliquity and the component of non-paretic hip elevation (A). The comparison in the severe ankle impairment group shows a significant increase in the component of limb-shortening and significant decrease in the component of hip elevation due to pelvic obliquity (B). The comparison in the mild ankle impairment groups shows a significant increase in toe clearance (C). Error bar indicates standard deviation. *P<0.05; **P< 0.01.
