A [PERSON]'s \(t\)-test showed that there was not a significant difference in stride times between the SRD (\(\overline{\text{X}}\) = 1.07, SD = 0.19 and neurotypical group \(\overline{\text{X}}\) = 1.06, SD = 0.15), t(16) = 0.30, \(p\) = 0.768. Table 2 indicates that the mean stride times between the two groups were not different. The peak velocities of the hip and knee of the SRD group were significantly less than those of the NT group, while there was no difference between the ankle velocities of the groups. Although the stride time CV does not reflect a noteworthy difference, the CVs for the peak velocities differ substantially. In all cases the CVs of the SRD group were greater than those of the NT group. Table 3 shows that the ROM of the hip and knee of the SRD group is significantly less than that of the NT group. Although trending in the same direction as the other joints, the SRD ankle is not significantly different than NT ROM, with the substantial variability of the SRD group likely accounting for the lack of significance. The CVs for all joints indicate that the relative variability of SRD participants is substantially greater than that of the NT participants. Figure 2 reflects that the basic mean movement pattern is fairly similar between the two groups but the amplitude of the SRD waveform across the stride is different for each joint (see also Tables 3 and 4). Table 4 presents the mean and SD SI values for the ROMs and peak joint velocities of each joint for both groups. These data reflect that the asymmetry between the two limbs, for both measures, is much greater in the SRD participants than the NT participants as all of the SRD values fall outside of the NT CI bounds. Table 5 represents that for each joint, the waveforms of the SRD group display a high degree of similarity with those of the NT group, but the vast majority of the SRD samples falls outside the CIs of the NT waveforms. \begin{table}
