Gait parameters under self-selected (SS) speed two-minute walk test (2MWT). Significantly different gait parameters among FXTAS, PD, and ET participants: (A) stride velocity variability, (B) cadence variability, (C) stride length, and (D) arm symmetry index. $\mathrm{C}\mathrm{o}\mathrm{V}\left(\mathrm{coefficient\; of\; variation}\right)=\frac{\mathrm{S}\mathrm{D}}{\mathrm{mean}}\times 100$ . All data reported as mean ± SEM. *p ≤ 0.05, **p ≤ 0.01.
