Table 4.

Comparisons of gait variability during phases of the walk and turn with obstacle task for PwMS. p-values (p) are reported for each comparison with effect sizes (r) indicated for significant differences. Comparisons: Pre-turn pre-obstacle to pre-turn post obstacle (pre-turn), pre-turn pre-obstacle to post-turn pre-obstacle (pre-obs), pre-turn post-obstacle to post-turn post-obstacle (post-obs), and post-turn pre-obstacle to post-turn post-obstacle (post-turn).
