已经开发出一种用于测量和分析正常和异常运动的运动学的电视计算机系统，该系统具有以下特点：对受试者或患者的干扰最小、确定解剖标志的绝对坐标、分析 3 或 4 步以及数据转换和分析的自动化。已经开发出利用标记坐标的准确性的分析技术，并适当应用降噪滤波，允许直接计算速度和加速度（线性和角度）。给出了其中一些导出参数与时间的关系的示例。对一组以缓慢、舒适和快速步调行走的正常受试者进行的统计研究结果得出了许多以前无法获得的速度和加速度范围。
A T.V.-computer system for the measurement and analysis of the kinematics of normal and abnormal locomotion has been developed which has the following characteristics: minimum encumberment to the subject or patient, determination ofabsolutecoordinates of anatomical landmarks, analysis of 3 or 4 strides, and automation of data conversion and analysis. Analysis techniques have been developed which take advantage of the accuracy of the marker coordinates, and with suitable application of noise reduction filtering, permit direct calculation of velocities and accelerations (both linear and angular). Examples of some of these derived parameters vs time are presented. The results of a statistical study on a group of normal subjects walking at slow, comfortable and fast cadences yield the ranges of many velocities and accelerations not previously available.
