Net ankle power during walking. a Net ankle power, P ankle , due to both biological and exosuit contributions, was estimated using standard 3D inverse dynamics. Ankle augmentation power, P aug_indirect , represents power provided by the exosuit that augments ankle plantarflexion. Biological ankle power, P ankle_bio_indirect , reflects the net power generated by muscles, tendons and other biological tissues about the ankle joint. Power results are shown for a representative stride cycle. b Positive and negative work (mean ± s.d.) during the walking cycle. Net work is indicated by thick white line on each bar
