动力学和时空步态分析为步态障碍患者的治疗和康复提供了重要信息。尽管配备红外运动捕捉相机和测力台的运动分析实验室是分析的黄金标准测量技术，但在大多数情况下，由于其成本、规模和可用性，它们对于社区卫生中心或一般临床环境来说是不切实际的。本文提出了一种易于使用的步态分析系统，该系统使用仪器鞋垫和激光距离传感器 (LRS) 的同步测量。在所提出的系统中，GRF 和 COP 通过对鞋垫进行传感器分析来估计。步幅、步频和步行速度由 LRS 测量。此外，通过准确测量足部的初始和最终接触时间，可在鞋垫处检测包括单肢支撑和双支撑的站立持续时间。通过测量直线行走并将结果与运动分析实验室获得的数据进行比较，对源自鞋垫传感器和 LRS 集成系统的 GRF 估计方法进行了验证。
Kinetic and spatiotemporal gait analysis provides important information for the treatment and rehabilitation of patients with gait disorders. Although motion analysis laboratories with infrared motion capture cameras and force plates are the gold standard measurement technologies for analysis, they are, in most cases, impractical for community health centers or general clinical settings because of their cost, scale, and usability. This paper presents an accessible gait analysis system that uses simultaneous measurements of instrumented insoles and a laser range sensor (LRS). In the proposed system, GRF and COP are estimated by sensor analysis taken from the insoles. Strides step width, cadence, and walking speed are measured by the LRS. In addition, stance durations including single limb support and double stance are detected at the insoles from accurate measurements of initial and end foot contact time. The GRF estimation method derived from the insole sensors and the integrated system with the LRS have been validated by measuring straight walking and comparing results with data obtained from motion analysis laboratories.
