The purpose of this study was to determine the effect that changes in the sagittal tilt of a shock absorbing pylon (SAP) would have on trans-tibial gait characteristics. To do this kinetic and kinematic parameters were studied. three subjects were studied and compared whilst using a limb with a SAP that has been optimally aligned with results obtained when the SAP was tilted anteriorly and posteriorly from the vertical. A hypothesis was set out regarding the change in force through the SAP that would occur when it was tilted and it was believed that this change in the SAP would also appear in changes to the ground reaction forces (GRF) measured. The relative joint angles were measured throughout all three alignments. The prosthetic foot was also instrumented in order to determine any changes in the transmitted forces that may also occur at the foot due to the alignment changes.
