Table 2.

Linear mixed model results for divergence exponents during weight transfer (λHS), early swing (λTO), and late swing (λMS) phases of gait. Reference conditions for feedback and cognitive task were baseline and single task. Bold terms indicate significance at an FDR-adjusted p < 0.05 level.
