The assessment of force plate measurements obtained from subjects with a pathological gait is normally carried out by a visual inspection of the force-time curves produced by the plate. It is shown that a valuable addition to that inspection is the derivation from the curves of Legendre polynomial coefficients, the first five coefficients being sufficient to indicate clearly, specific osteoarthritic abnormalities.
对患有病理性步态的受试者所获得的测力板测量结果的评估，通常是通过目视检查测力板产生的力-时间曲线来进行的。结果表明，对该检查的一个有价值的补充是从曲线中推导勒让德多项式系数，前五个系数就足以清楚地表明特定的骨关节炎异常情况。
