Stance phase mechanical characterization of transtibial prostheses distal to the socket : a review

Abstract

Achieving the required functionality of a trans-tibial 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; and only in a few notable cases have authors reported
studies in which these two approaches are combined. 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 paper 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.
