Deviation from 100 % step length symmetry between affected and intact sides for walking at 1 m/s (a) and 1.25 m/s (b). Significant differences (p ≤ 0.05) in symmetry magnitude are denoted by a star (improved symmetry due to using the VI Knee) or a circled star (reduced symmetry). Positive values indicate longer step lengths with the affected side leg (standing on the intact side) compared to the intact side, negative values denote shorter steps with the affected leg compared to the intact side
