Fifty strides of a non-ataxic control group as well as 50 strides of an ataxic study group were analyzed and compared. T, thoracic limbs; P, pelvic limbs; N, number of steps; STDEV, standard deviation; CV, coefficient of variation; Highlighted cells, absolute values (restricted comparability); see Table 1 for detailed definitions of spatio-temporal and kinetic gait parameters and Supplementary Table S2 for descriptive statistics.
