چکیده

Background: the performance of the subjects with above-knee amputation is noticeably poorer than normal subjects. various types of components have been designed to compensate their performance. among various prosthetic components, the knee joint has great influence on the function. two types of knee joints (3r15, 3r20) have been used broadly for above-knee prostheses. however, there is not enough research to highlight the influence of these joints on the gait performance of the subjects. therefore, an aim of this research was to investigate the performance of the above-knee amputees while walking with 3r15 and 3r20 knee joints. materials and methods: 7 above-knee amputees were recruited in this research study. they were asked to walk with a comfortable speed to investigate the gait function of the subjects with 3 cameras 3d motion analysis system (kinematrix system). the difference between the performances of the subjects with these joints was compared by use of paired /-test. results: the results of this study showed that, the performances of the subjects with 3r20 were better than that with 3r15. the walking speed of the subjects with 3r20 was 66.7 m/min compared to 30.4 m/min (p-value = 0.045). moreover; the symmetry of walking with 3r20 was more than that with 3r15, based on the spatio- temporal gait parameters values (p-value <0.05). conclusion: the difference between the performances of the subjects with 3r20 and 3r15 knee joints was related to the walking speed, which improved while walking with 3r20 joint.
