研究了步态动力学分析中位置历史二次微分的噪声放大问题。需要测量信号和噪声的频域特性，以定量评估原始、滤波和动态步态数据中的误差。使用12名受试者和共30个步态记录的步态的频率内容进行了测定。
Amplification of noise in double differentiation of position histories for dynamic analysis of gait was studied. Measurements of the frequency domain characteristics of signal and noise are required to quantitatively assess errors in raw, filtered and dynamic gait data. The frequency content of gait using 12 subjects and a total of 30 gait records was determined.
