[Purpose] The purpose of this study was to investigate the effect of the timing of leg support elevation on the horizontal force acting on the buttocks in a reclining wheelchair. [Subjects and Methods] The participants were 17 healthy men. Two experimental conditions were tested: the leg-down and leg-up conditions. The back support was reclined at increasing angles, from the initial upright position (IUP), proceeding to the fully reclined position (FRP), and returned to the upright position (RUP). The posterior inclination phase was from IUP to FRP, and the returning inclination phase was from FRP to RUP. [Results] The horizontal force under the leg-up condition was significantly higher than that under the leg-down condition in all positions of back support. [Conclusion] The leg supports should be positioned downward before reclining the back support of a wheelchair.
[目的] 本研究旨在探讨在躺式轮椅中腿部支撑抬高时机对作用于臀部的水平力的影响。[对象与方法] 参与者为17名健康男性。测试了两种实验条件：腿部放下和腿部抬起条件。靠背从初始直立位置（IUP）以递增角度倾斜至完全躺平位置（FRP），然后再回到直立位置（RUP）。后倾阶段为从IUP到FRP，返回倾斜阶段为从FRP到RUP。[结果] 在靠背的所有位置，腿部抬起条件下的水平力均显著高于腿部放下条件下的水平力。[结论] 在倾斜轮椅靠背之前，腿部支撑应向下放置。
