这项研究的目的是通过一个有动力的脚踝-脚-外骨骼来分析趾屈肌在步行到跑步转变(WRT)中的作用。11名女性受试者在加速的跑步机上进行了几次WRT，同时她们的足底屈肌在推开过程中得到了帮助或抵抗。在抵抗条件下的WRT速度低于控制条件下的WRT速度，这支持了以前的模拟、描述性和实验研究的假设。在辅助状态下，WRT速度没有增加，这与另一项研究相反，在另一项研究中，在腰部水平水平牵引间接帮助了足屈肌的推出。在本研究中，缺乏辅助条件的影响可能是由于实验操作的狭隘性质所致。(C)2009爱思唯尔B.V.保留所有权利。
The goal of this study was to analyse the role of the plantarflexor muscles in the walk-to-run transition (WRT) by means of a powered ankle-foot-exoskeleton. 11 female subjects performed several WRT's on an accelerating treadmill while their plantarflexors were assisted or resisted during push off. The WRT speed was lower in the resist condition than in the control condition which reinforces hypotheses from previous simulations, descriptive and experimental studies. There was no increase in WRT speed in the assist condition which is in contrast to another study where the plantarflexor push off was assisted indirectly by a horizontal traction at waist level. The lack of effect from the assist condition in the present study is possibly due to the narrowly focused nature of the experimental manipulation. (C) 2009 Elsevier B.V. All rights reserved.
