Abstract

The purpose of this quasiexperimental study was to test the effects of wearing the NewGait rehabilitative device on walking abilities in individuals with foot drop. The study involved 16 participants with foot drops caused by stroke (11 participants), multiple sclerosis (one participant), and peripheral neuropathies (four individuals). During a single testing session, participants walked 12 m at their self-selected speed in four experimental conditions: walking without any orthotic device; walking while wearing a regular plastic posterior leaf ankle foot orthosis (AFO); walking with the NewGait device assisting ankle dorsiflexion only; and walking with the NewGait device assisting the hip, knee, and ankle joint motions. Body motions during walking were recorded using a 3D system for motion analysis and analyzed with a set of spatiotemporal and kinematic parameters and a gait decomposition index. The gait decomposition index indicated sagittal interjoint coordination in the three joint pairs (hip-knee, knee-ankle, and hip-ankle) of the paretic (foot drop) leg during walking and was validated in a previous study. Overall, wearing all three orthotic devices improved the gait velocity, ankle dorsiflexion, and foot clearance compared to gait trials in which no assistive devices were used. However, wearing the AFO significantly restricted the plantarflexion range of motion and decreased interjoint coordination as measured by joint decomposition. In contrast, the NewGait device altered the ankle plantarflexion motions but also increased coordinated movement (reduced the decomposition) in most lower-extremity joint pairs and conditions. Therefore, the NewGait rehabilitative device can be considered superior to a regular AFO in correcting gait deviations caused by foot drop.

NewGait 康复设备可矫正足下垂患者的步态偏差。
这项准实验研究旨在测试佩戴 NewGait 康复设备对足部下垂患者行走能力的影响。这项研究涉及 16 名参与者,他们分别因中风(11 人)、多发性硬化症(1 人)和周围神经病(4 人)而导致足下垂。在单次测试过程中,参与者在以下四种实验条件下以自选速度行走 12 米:不佩戴任何矫形器行走;佩戴普通塑料后叶踝足矫形器(AFO)行走;佩戴仅辅助踝关节背屈的 NewGait 装置行走;佩戴辅助髋关节、膝关节和踝关节运动的 NewGait 装置行走。使用三维运动分析系统记录行走时的身体运动,并使用一组时空和运动学参数以及步态分解指数进行分析。步态分解指数显示了瘫痪(足下垂)腿在行走过程中三个关节对(髋关节-膝关节、膝关节-踝关节和髋关节-踝关节)的矢状关节间协调性,并在之前的研究中得到了验证。总体而言,与未使用辅助装置的步态试验相比,佩戴三种矫形装置都能改善步态速度、踝关节外展和足部间隙。然而,佩戴 AFO 会明显限制跖屈的活动范围,并降低关节间的协调性(以关节分解度为衡量标准)。相比之下,NewGait 设备不仅改变了踝关节的跖屈运动,还增加了大多数下肢关节对和条件下的协调运动(减少了分解)。因此,可以认为 NewGait 康复装置在纠正足下垂造成的步态偏差方面优于普通 AFO。
