Distribution of joint work during walking on slopes among persons with transfemoral amputation

“…In the present study, the positive work estimated by the individual limb method for the contralateral limb reached 1.32 +/-0.23 J/kg during upslope walking which corresponds to an increase of 40% compared to AB subject in the same situation despite of a lower gait speed. A major part of this increase comes from the ankle which can present a premature positive power at midstance which is specific of vaulting gait (Villa et al, 2015).…”
