Load during prosthetic gait : is direct measurement better than inverse dynamics?

By Raphael Dumas, Laurence Cheze and Laurent A. Frossard


The knee forces and moments estimated by inverse dynamics and directly measured by a multiaxial transducer were compared during the gait of a transfemoral amputee. The estimated and directly measured forces and moments were relatively close. However, 3D inverse dynamics estimated only partially the forces and moments associated with the deformation of the prosthetic foot and locking of knee mechanism
