摘要

我们通过分析步态节奏来估计小脑共济失调的严重程度。我们测量了单纯性小脑共济失调患者和健康对照组的步频，然后分析了相邻时间比率的分布。如果用幂律分布和对数正态分布之和来表示，两组患者的步态节律显示出最佳的适应性，并且可以通过幂律分布的指数来区分两组，这反映了步态节律的分形特性。步态节律可能反映了小脑共济失调患者的不同障碍特征，因此是小脑共济失调的一种有用的连续量表。

Gait rhythm analysis as a new continuous scale for cerebellar ataxia: Power law and lognormal components represent the ataxic gait quantity

We estimated the severity of cerebellar ataxia by analyzing gait rhythm. We measured the step times in patients with pure cerebellar ataxia and healthy controls and then analyzed the distribution of the ratios of adjacent times. Gait rhythm displayed the best adaptation when expressed as the sum of the power law and lognormal distributions in both groups, and the groups could be distinguished by the exponent of the power law distribution, reflecting the fractal property of gait rhythm. Gait rhythm might reflect different features of impairment in patients with cerebellar ataxia, making it a useful continuous scale for cerebellar ataxia.
