A walking support orthosis known as the e-foot®, a rubber orthotic worn from the hip to the forefoot to enhance joint flexibility and movement, has been developed to assist elderly people and individuals with walking impairments. Despite its widespread acceptance and positive reception in some care settings, the precise impact of this device on gait dynamics remains unexplored. This study aims to bridge this gap by comparing the walking speeds of healthy volunteers using the e-foot® against their normal walking speeds. Furthermore, it seeks to elucidate the biomechanical alterations induced by the e-foot® on their gait patterns.
In this intervention study, 78 healthy volunteers underwent a 10-m walk test, both with and without the e-foot®, to measure its effect on walking speed. Gait changes were biomechanically compared by analyzing marker positions and accelerations of the lower extremities during the walk tests.
The e-foot® orthotic device significantly improved walking times for both men and women in the 10-m walk test. Biomechanical testing showed a consistent trend of higher marker positions of the knees, heels, and toes when participants were using the e-foot®. Additionally, marker acceleration during the first half of the swing phase was greater with the e-foot®, indicating a faster gait initiation.
The e-foot® increased the walking speed of healthy volunteers. Also, there were changes to knee, heel and toe positions during gait, and comparative increase in acceleration was recorded in these three parts during swinging gait.
一种名为“电子脚”(e-foot®)的步行辅助矫形器已被开发出来,它是一种从臀部到前脚掌佩戴的橡胶矫形器,旨在增强关节灵活性和运动能力,以帮助老年人和行走障碍者。尽管该设备在一些护理环境中得到了广泛认可和积极反馈,但其对步态动力学的确切影响仍未得到探索。本研究旨在通过比较使用“电子脚”(e-foot®)的健康志愿者的步行速度与他们的正常步行速度来填补这一空白。此外,研究还试图阐明“电子脚”(e-foot®)对其步态模式所引起的生物力学变化。
在这项干预性研究中,78名健康志愿者在佩戴和不佩戴“电子脚”(e-foot®)的情况下分别进行了10米步行测试,以测量其对步行速度的影响。通过分析步行测试期间下肢的标记位置和加速度,对步态变化进行生物力学比较。
在10米步行测试中,“电子脚”(e-foot®)矫形器显著缩短了男性和女性的步行时间。生物力学测试表明,当参与者使用“电子脚”(e-foot®)时,膝盖、脚跟和脚趾的标记位置始终呈现更高的趋势。此外,在摆动阶段的前半段,使用“电子脚”(e-foot®)时标记加速度更大,表明步态启动更快。
“电子脚”(e-foot®)提高了健康志愿者的步行速度。此外,步态期间膝盖、脚跟和脚趾的位置发生了变化,并且在摆动步态期间这三个部位的加速度相对增加。
