美国联合技术公司（Hartford， CT， USA）于1980年在纽因顿儿童医院开发了步态分析实验室，其临床目的是提供人体运动的量化评估，以协助各种儿科步态病理的矫形治疗。运动测量系统采用基于视频的数据收集策略，类似于商业上可用的运动数据收集系统。放置在受试者身上的解剖对齐、被动、反向反射标记被照亮、检测并存储在专用相机硬件中，同时从力平台和肌电传感器获取数据。三维标记点位置信息用于确定：(i)分段嵌入坐标系的方向，（ii）瞬时关节中心位置，（iii）关节角度。关节动力学，i-e。，力矩和功率，也可以计算，如果收集有效的力板数据。
The clinical objective of the gait analysis laboratory, developed by United Technologies Corporation (Hartford, CT, USA) in 1980, at the Newington Children's Hospital is to provide quantified assessments of human locomotion which assist in the orthopaedic management of various pediatric gait pathologies. The motion measurement system utilizes a video-based data collection strategy similar to commercially available systems for motion data collection. Anatomically aligned, passive, retroreflective markers placed on the subject are illuminated, detected, and stored in dedicated camera hardware while data are acquired from force platforms and EMG transducers. Three-dimensional marker position information is used to determine: (i) the orientation of segmentally-embedded coordinate systems, (ii) instantaneous joint center locations, and (iii) joint angles. Joint kinetics, i-e., moments and powers, may also be computed if valid force plate data are collected.
