  1. Bold values indicates statistical significant p < 0.05.
  2. Group comparisons were assessed using independent‐sample t-tests for normally distributed continuous variables and Wilcoxon rank-sum for non-normally distributed continuous variables, denoted bya. Gait data were available for 28 of 34 participants.
  3. Data are mean (standard deviation) unless otherwise noted.
