Violin plots of the six most important gait parameters to distinguish between patients with normal and abnormal EMG.

<p>The vertical axis represents the value of the gait parameters studied. The shape of the violin plot depends on the distribution of the values of the gait parameters in each group. Grey violin plots show data distribution from healthy children, the green ones data distribution from children with HSP and normal EMG and the red ones distribution from children with HSP and abnormal EMG. In each violin plot, the white point represents the median value of each group; the vertical black line represents the range.
