Figure 2

Ensemble-averaged sagittal IA and RCIA for the TCC (black curves) and Control (red curves) groups when crossing obstacles of 10% LL (solid), 20% LL (dashed), and 30% LL (dotted). Vertical lines indicate selected crossing events: leading toe-off (T1); leading toe above the obstacle (T2); leading heel-strike (T3); trailing toe-off (T4); trailing toe above the obstacle (T5).
