ST: Stride Time; units seconds. Duty Factor (DF), EMG Stance (EMG St), and EMG Swing (EMG Sw) asymmetry scores are the percent difference between the healthy and injured leg (i.e. 0.5 indicates that the between leg difference is 50% that of the healthy leg). EMG(t), AP(t), ML(t), and CC(t) are pattern asymmetries for the sEMG time-series and the antero-posterior, medio-lateral, and cranial-caudal thigh acceleration time-series respectively. Composite asymmetry score (Comp.) is the average value of the other seven asymmetry scores. Bold numbers in the pairwise comparisons are effect sizes (*p ≤ 0.05, **p ≤ 0.01) and non-bold numbers are the p values for non-significant pairwise differences.
