Adaptation to walking with an exoskeleton that assists ankle extension

Highlights ► Bilateral pneumatic ankle-foot exoskeletons with kinematic control were studied. ► The ankle-foot exoskeleton showed a metabolic adaptation after 18.5 ± 5 min. ► Metabolic cost was reduced with 16% compared to unpowered walking during adaptation. ► Metabolic reduction was accompanied wi...

Description
Summary:Highlights ► Bilateral pneumatic ankle-foot exoskeletons with kinematic control were studied. ► The ankle-foot exoskeleton showed a metabolic adaptation after 18.5 ± 5 min. ► Metabolic cost was reduced with 16% compared to unpowered walking during adaptation. ► Metabolic reduction was accompanied with reduced muscle activity in plantarflexors. ► The exoskeleton showed fast adaptations and significant reductions in metabolic cost.
