The purpose of this study is to analyze the visualization of various parameters on the kinetic variables that is the force of moment. It is the useful tools that PCA(principle component analysis) algorithm is acquired fast robust and highly the rate of recognition at enormous amount of the first raw data in Gait Analysis, relatively. Using VICON 512 Motion Analysis System, the collected parameter of the force of moment(Torque) was analyzed 3D Motion Plane(sagittal, frontal, horizontal), and then lower Joints(Hip, Knee, Ankle) were processed utilizing Matlab.(ver 7.0.4) program with the raw variable data was assessed by PCA algorithm. Additionally, the statistical procedure was the factor analysis performed by SPSS(ver 12.0). For this study, PCA methods which were assessed the moment parameters of hip, knee and ankle joint, respectively. As a results, The linear regression equations showed, that is the sagittal plane, hip joint(y=0.34x-0.43), knee joint(y=-0.23x+0.21) and ankle joint(y=-1.01x-0.37) the frontal plane, hip joint(y=0.22x-0.35), knee joint(y=0.58x+0.18) and ankle joint(y=-1.08x-0.02) the horizontal plane, hip joint(y=0.94x-0.19) and knee joint(y=-1.01x-0.37). In conclusion, hip joint was mainly correlated with the stability, the propulsion and the balance. Also the knee joint was correlated with both the shock absorption and the balance, Another the ankle joint was the propulsion. Additionally, these results were interpreted to be valuable visualization methods which were the PCA factors(stability, propulsion, balance and energy efficiency) of the kinetic variables in free normal walking.
