2. Fig 1
Means and SDs of spatiotemporal variables. The left-side plots are all participants, and the right-side plots are participants separated into HY stage 2 and HY stage 3. (A and B) Normalized velocity, (C and D) normalized stride length, (E and F) normalized cadence, and (G and H) normalized stride time variability. Abbreviations: COG, participants told to think “big” steps; PREF, preferred pace; VER, participants told “big step” while walking; VIS, visual cues; *P<.05.
