Sobolev norm value changes. a–c Box and whisker plots illustrating median and interquartile ranges for Sobolev norm value changes of the dominant/non-paretic and non-dominant/paretic legs for all LF, HF, and CG participants. Changes for force and post-force epochs as well as the cane condition are relative to respective pre-force epoch norms. d Sobolev norm values vs gait speed correlation plots for dominant/nonparetic and nondominant/paretic legs. Provided are r values for the bilateral lower limbs across all data and subdivided for LF, HF, and CG groups during pre-force, leash (force and post-force), and cane data. Statistically significant original values relative to pre-force as well as statistically significant bilateral comparisons are denoted by * (p < 0.05)
