The effect of shock-absorbing pylon stiffness on prosthetic mechanical work during walking

This abstract has open access
Abstract Summary
A prosthetic shock-absorbing pylon (SAP) attenuates impact forces to dissipate shock in individuals with amputation. However, it is unclear how a SAP and their spring stiffness affect the mechanical work done by the prosthetic limb. We observed that SAP spring stiffness had a speed-dependent effect on the energy dissipated, but not generated, which suggests a damping effect from the prosthesis.
