The Movement Model of the Knee Joint during Human Walking

Targeting at the healthy young men, the method of experiment is applied in researching the knee mathematical model of sports features during walking. On the base of the experimental data, the knee movement is described in the graph. Using the regression analysis method of expanded the Gaussian functions and the sine function section combining, a mathematical model is derived. The correlation analysis results by the change of speed and height do not affect the amplitude of knee joint motion significantly, while the height is not related to amplitude, and walking speed is positively correlated with the amplitude trends. The experimental data verify the correctness of the conclusion, they also explain the model has a certain universal significance. The limitation of the graphical representation can only be used on qualitative analysis in the past is surmounted. The results have a certain value and scientific significance on the gait rehabilitation training, walking functional evaluation and humanoid robotics.
