SUMMARY

We studied the effects of anterior-posterior (AP) and mediolateral (ML) oscillations on control of stability during walking in humans. We found that independent of
perturbation applied, mean ML margins of stability remained approximately constant whereas AP margins of stability were influenced by ML perturbations more than AP perturbations.
Our results support the idea that maintaining lateral margin of stability magnitude could be a goal in controlling human walking.
