Footfall Patterns.

<p>Footfall pattern recordings in one individual with HD under five conditions (A) no assistive device and using a (B) cane, (C) standard walker, (D) two-wheeled walker or (E) four-wheeled walker. The four-wheeled walker (E) produced a gait pattern with the least variability.</p

Coefficients of Variation.

<p>Comparison of mean coefficients of variation across six walking conditions: (A) step time and (B) stride length coefficients of variation (CV) with standard deviation. Variability was consistently low when using the four-wheeled walker (4WW); no AD, no assistive device; StW, standard walker; 2WW, two-wheeled walker; 3WW, three-wheeled walker; *significantly different than no AD at <i>p</i><.05. * significantly different than no AD at p<.05; † significantly different than cane at p<.05; # significantly different than StW at p<.05; ∞ significantly different than 3WW at p<.05; § significantly different than 2WW, 4WW at p<.05; Ψ significantly different than cane and 4WW at p<.05.</p

Figure of Eight Course.

<p>Comparison of mean time and stumbles on a figure of eight course: (A) mean time with standard deviation for one lap around figure-of-eight course and (B) number of stumbles and number of individuals who stumbled walking in the figure-of-eight course across conditions; no AD, no assistive device; StW, standard walker; 2WW, two-wheeled walker; 3WW, three-wheeled walker; 4WW, four-wheeled walker. * significantly different than no AD at <i>p</i><.001.</p
