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. It was found that the sex-related variation is more significant than the age-related variation in adult gait. This data base can serve as a common reference for comparison.
报告了148名成年人在平地上行走时时间距离因素、膝关节运动和地面反作用力模式的规范数据库。使用参数化和非参数化（傅里叶级数）表示法对数据进行研究，以促进统计分析。关键参数按年龄和性别划分。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。将所有典型模式合并以构建“一般”模式。确定了基本数量和最显著的傅里叶系数。研究发现，在成人步态中，与性别相关的变化比与年龄相关的变化更显著。该数据库可作为比较的通用参考。
