A method is derived to calculate the amount by which a subject's gait deviates from an average normal profile, and to represent this deviation as a single number. The method uses principal component analysis to derive a set of 16 independent variables from 16 selected gait variables. The sum of the square of these 16 independent variables is interpreted as the deviation of the subject's gait from normal. Statistical tests of the method's validity and an initial demonstration of its clinical utility are included. It is found that using this index, increasing clinical involvement corresponds to increasing index score.
一种方法被推导出来，用于计算受试者步态与平均正常轮廓的偏差量，并将这种偏差表示为一个单一数字。该方法使用主成分分析从16个选定的步态变量中导出一组16个独立变量。这16个独立变量的平方和被解释为受试者步态与正常步态的偏差。文中包括了该方法有效性的统计测试及其临床效用的初步证明。研究发现，使用这个指标，临床参与度的增加与指标得分的增加相对应。
