Abstract

Background: Patients with stroke with hemiplegia often experience gait impairments and use ankle foot orthoses (AFOs) to support their walking. Despite the wide use of AFOs, the specific impact of dorsiflexion control in AFOs on gait parameters has yet to be clarified.

Objectives: This study aimed to evaluate the effects of 2 types of AFOs with different dorsiflexion control mechanisms on gait parameters in patients with stroke with hemiplegia.

Study design: A cross-sectional comparative study.

Methods: Eleven patients with stroke with hemiplegia were analyzed using 2 types of AFOs: a dorsiflexion-assisted AFO (Gait Solution Design®: GSD) and a bidirectional control AFO (WalkOn Trimable®: WOT). Gait analysis was performed using 3-dimensional motion analysis to measure gait speed, ankle plantarflexion moment, hip extension angle, shank inclination angle, and the percentage of terminal stance. Statistical analyses were conducted to compare the effects of GSD and WOT on these gait parameters.

Results: The GSD significantly increased ankle plantarflexion moment and shank inclination angle, supporting the heel rocker (HR) and ankle rocker (AR) functions. In contrast, the WOT significantly increased hip extension angle and the percentage of terminal stance, facilitating the Forefoot Rocker function.

Conclusions: For patients with stroke with impaired HR and AR function, dorsiflexion-assisted AFOs like GSD are preferable. For patients with established HR and AR function but impaired Forefoot Rocker, bidirectional control AFOs such as WOT are recommended.

踝足矫形器对脑卒中偏瘫患者背屈控制对步态参数的影响。

背景：卒中偏瘫患者经常出现步态障碍，使用踝足矫形器（AFOs）来支持他们的行走。尽管afo被广泛使用，但afo中背屈控制对步态参数的具体影响尚未明确。目的：本研究旨在评价2种不同背屈控制机制的afo对脑卒中偏瘫患者步态参数的影响。研究设计：横断面比较研究。方法：对11例脑卒中偏瘫患者进行分析，采用2种AFO：背屈辅助AFO（步态解决方案设计®：GSD）和双向控制AFO （WalkOn Trimable®：WOT）。采用三维运动分析进行步态分析，测量步态速度、踝关节跖屈力矩、髋关节伸角、小腿倾角、终站姿百分比。统计学分析比较GSD和WOT对这些步态参数的影响。结果：GSD显著增加踝关节跖屈力矩和小腿倾角，支持足跟摇臂（HR）和踝关节摇臂（AR）功能。相比之下，WOT显著增加了髋部伸展角度和终端姿势的百分比，促进了前足摇臂的功能。结论：对于HR和AR功能受损的脑卒中患者，GSD等背屈辅助afo更可取。对于已建立HR和AR功能但前足Rocker受损的患者，建议使用双向控制afo，如WOT。
