Abstract

This report describes the complete design and testing of a methodology for the creation of a force sensing device that can be used to provide clinically significant data to aid a prosthetist in the static alignment of a transtibial prosthesis fitting. Thin-film force transducers form the basis for the prototype force sensing module that is integrated into a prosthetic leg for the testing and future alignment fittings. This physical force sensing device was used along with a computer simulation of the limb and module to collect force measurement results, both positionally relative and absolute. The experimental data collected were analyzed using Analysis of Variance, effects plots and prediction equations. The statistical analysis helped to evaluate the feasibility of using similar data and methods for producing a system capable of predicting and validating changes in force distribution relationship, the accuracy of the force sensing module could be improved. The recommendations for future revisions of this design include using more accurate force sensors and conducting more replications of the physical testing.
