Successful preliminary walking experiments on a transtibial amputee fitted with a powered prosthesis

This paper presents the results of preliminary walking experiments on a
transtibial amputee wearing a powered prosthesis. The prosthesis prototype serves
as a proof-of-concept implementation for investigating the potential of pleated
pneumatic artificial muscles to power a transtibial prosthesis. The device is
equipped with pleated pneumatic artificial muscles, and tethered to a laboratory
pressure source. The prosthesis is capable of providing the amputee with 100% of
the required push-off torque and it can adapt its joint stiffness to the walking
speed. This study supports the hypothesis that a powered transtibial prosthesis
with adaptable stiffness might be beneficial to the amputee.
