Shock-absorbing pylons (SAP) are as effective as rigid pylons for people with below-the-knee amputations. In this study, a commonly prescribed SAP is compared to a conventional rigid pylon. The pylons were assessed for effect on gait mechanics, transmitted accelerations, and functional outcomes using step counts and questionnaires. The only statistically significant finding was for the prosthetic-side knee angle at initial contact. Volunteers displayed an average of 2.6В° more flexion with the rigid pylon than the SAP while walking at a controlled speed. This result indicates that individuals with below-the-knee amputations can adjust the stiffness of their residual limb in response to changes in prosthetic component stiffness.
