Abstract

This paper presents a novel low-cost and fully-portable instrumented shoe system for gait phase detection. The instrumented shoe consists of 174 independent sensing units constructed based on an off-the-shelf force-sensitive film known as the Velostat conductive copolymer. A zero potential method was implemented to address the crosstalk effect among the matrix-formed sensing arrays. A customized algorithm for gait event and phase detection was developed to estimate stance sub-phases including initial contact, flat foot, and push off. Experiments were carried out to evaluate the performance of the proposed instrumented shoe system in gait phase detection for both straight-line walking and turning walking. The results showed that the mean absolute time differences between the estimated phases by the proposed instrumented shoe system and the reference measurement ranged from 45 to 58 ms during straight-line walking and from 51 to 77 ms during turning walking, which were comparable to the state of art.Clinical and Translational Impact Statement—By allowing convenient gait monitoring in home healthcare settings, the proposed system enables extensive ADL data collection and facilitates developing effective treatment and rehabilitation strategies for patients with movement disorders.

基于足底压力数据的低成本步态相位检测仪表鞋系统

提出了一种新型的低成本、全便携的步态相位检测仪器鞋系统。仪表鞋由174个独立的传感单元组成，基于一种现成的力敏感薄膜，称为Velostat导电共聚物。提出了一种零电位方法来解决阵型传感阵列间的串扰效应。开发了一种步态事件和相位检测的自定义算法，用于估计初始接触、平足和推离等姿态子相位。实验验证了所提出的仪器鞋系统在直线行走和转弯行走步态相位检测中的性能。结果表明，在直线行走和转弯行走中，所提出的仪器化鞋系统与参考测量的相位估计的平均绝对时间差在45 ~ 58 ms之间，在51 ~ 77 ms之间，与目前的技术水平相当。临床和转化影响声明-通过在家庭医疗保健环境中方便的步态监测，拟议的系统可以广泛收集ADL数据，并促进为运动障碍患者制定有效的治疗和康复策略。
