Abstract

People have always been interested in analyzing human movement and gait. The aim of gait analysis of amputee who has lost a lower limb is to improve their lifestyle. Currently, there are over ten million amputees in the world and more than 250,000 people lose their limb every year. For designing smart prosthetic legs to improve amputees’ life, at first we should be able to control mechanical parameters. The intent of this research report is to find the correlations and interpretation of such correlations of kinetics and kinematics parameters of knee joint in 4-linkage bar transfemoral prosthetic leg for future design of smart prosthetic leg. A three dimensional motion analyzer with seven infrared cameras and two force plates was used to collect data. Then, the collected data were analyzed by Matlab, SPSS, and Microsoft Excel. Finally, the regression formula for three couple of parameters was extracted and the moderate direct association of knee moment and knee angle, moderate inverse correlation of knee power and knee moment, and major inverse correlation between knee power and knee angle were obtained from the analysis of the experimental tasks.
