Achieving the required functionality of a transtibial prosthesis during the
stance phase of gait (e.g., shock absorption, close to normal
roll-over
characteristics, and smooth transition into swing) depends on the Amputee
Independent Prosthesis Properties (AIPPs), defined here as the mechanical
properties of the prosthesis that directly influence the performance of the
amputee. Accordingly, if research studies are to advance the design of prostheses
to achieve improved user performance, AIPPs must be a primary consideration.
However, the majority of reported studies can be categorized as either human
performance testing of commercial prosthetic components or AIPP characterization;
only in a few notable cases have studies combined these two approaches. Moreover,
very little consistency exists in the current methods used for AIPP
characterization, thus making comparisons between the results of such studies
very difficult. This article introduces a framework for studying prosthesis
design, which includes AIPP characterization, human performance and/or gait
simulation studies, and detailed design. This framework provides a structure for
reviewing previous approaches to AIPP characterization, discussing both their
merits and shortcomings and their use in previous experimental and simulation
studies. For the purposes of this review, stance phase AIPP models have been categorized as either lumped parameter or roll-over shape based.
