摘　　要：提出了危势轨迹图技术新概念,并以此为基础进行截瘫功能性电刺激(FES)行走的步态信息分析和处理.危势轨迹图技术是利用步行器倾翻指数作为评估因子来直观显示截瘫患者在行走过程中步态稳定性的时空表现,其核心构件为一套基于12导联应变片电桥网络的步行器测力系统.通过相应的系统校准和临床测试结果表明,该技术是集测量、处理、显示、分析功能于一体而形成的一个较完整的研究手段,可用于截瘫的临床康复指导,并有望为未来FES闭环反馈控制系统的研制奠定基础.This paper presents a new technique concept calle d risk-trend-graph(RTG), which is used to analyze and process paraplegic walking gait assisted with functional electrical stimulation(FES). This technique takes walker rolling index as the evaluating factor to indicate the temporal and spat ial gait stability conditions during the walking process of paraplegia patient. Its main component is a walker dynamometer system based on the 12-channel strai n gauge bridge network. Relevant system calibration and clinical test results sh ow that this technique is an integrated research tool with the functions of meas urement, processing, display and analysis, which may be applied to paraplegic re habilitation guide in clinics and lay a foundation for the development of closed -loop feedback FES system in the future.
