Minimization of metabolic cost of transport predicts changes in gait mechanics over a range of ankle-foot orthosis stiffnesses in individuals with bilateral plantar flexor weakness.

In midstance, positive knee joint work decreased, negative knee joint work increased and vasti metabolic power decreased, while hamstrings metabolic power did not show a clear trend with increasing AFO stiffness.

Peak total ankle moment was approximately constant in the experiments but showed an increasing trend in the predictive gait simulations ( Figure 2 ; Figure 3 , Supplementary Table S1, S5 ). 3.2 Simulated AFO effects on mCoT and muscle metabolic consumption The mCoT showed a clear minimum with increasing stiffness in both the simulated and individual experimental results ( Figure 4 ).
