Towards the definition of a functionality index for the quantitative evaluation of hand-prosthesis

Based on the analysis of the parameters considered as more relevant for the evaluation of hand performances, a functionality index is proposed. The aim of this study is the definition of a functionality index that provides a quantitative measure of hand prosthesis functionality. A clinical analysis of the global efficiency of such prosthesis based on their characteristics has enabled us to determine some parameters from which prosthetic hands can be evaluated and compared. This quantitative evaluation could be a tool to learn about prosthesis and help on further designs.
