Group average foot placement interlimb symmetry during day 1 adaptation (A), between-day retention (B), i.e., early adaptation on day 1 (abrupt group only) vs. day 2 (both groups), day 2 adaptation (C), day 2 washout (D), and between-day aftereffects (E), i.e., late baseline on day 1 vs. early baseline on day 2. Black squares represent the abrupt group; grey diamonds represent the gradual group. Errors bars, ±1SD. #Significant group × epoch interaction; *significant main effect of epoch.
