Inversion-eversion control may affect amputees balance during walking.

Individuals with below knee amputation exert more effort during walking than their able-bodied counterparts. This increased effort may be partially due to increased balance-related effort, especially while walking on challenging terrain. Recently, we found that balance-related effort can be reduced by modulating ankle push-off work with a robotic ankle-foot prosthesis. However, we also realized the unexplored potential of active ankle in/eversion control as a balancing resource.
