本文报告了148名成人水平步行时的时间距离因素、膝关节运动和地面反力模式的规范性数据库。使用参数和非参数（傅立叶级数）表示法研究数据，以便于统计分析。根据年龄和性别划分关键参数。对每个正常受试者的个体力和运动曲线进行平均以建立典型模式。将所有典型模式组合起来构成一般模式。确定了必要数和最重要的傅立叶系数。成年人步态的性别差异明显大于年龄差异。这个数据库可以作为比较的共同参考。
A normative data base of temporal distance factors, knee joint motion and ground reaction force patterns for 148 adults during level walking is reported. The data were studied using parametric and non-parametric (Fourier series) representations to facilitate statistical analyses. Key parameters were divided according to age and sex. Individual force and motion curves of each normal subject were averaged to establish the typical patterns. All typical patterns were combined to construct the general patterns. The essential number and most significant Fourier coefficients were determined. The sex-related variation apparently is more significant than the age-related variation in adult gait. This data base can serve as a common reference for comparison.
