Analysis of gait with above-knee prosthesis using a new gait analysis system. Body's center of gravity and computer graphics

Changes in the human body's center of gravity white walking with above. knee prosthesis were examined, using a new gait analysis system. This system can be synchronized with computer graphics (CG)which allow graphical representation and observation from any selected viewpoint. Three individuals with above-knee prothesis were enrolled in this study,including an individual in the early stages of training individual in the middle stages of gravity(COG)was analyzed in each of these individuals while they walked,using the above system,and was compared with the data from 3 healthy controls. The mean magnitude of dislocation of the COG was greater during prosthetic walking than during the walking of healthy individuals,as we had expected. However,this parameter for experienced artificial limb users was very close to that of healthy individuals. Synchronization of this analysis system with CG was found to allow simple indentification of problems even by inexperienced examiners.
