In our country which is an aging society, hundreds of thousands of a year become the gonarthrosis. It is thought that the causes are senescence, daily living environment, and walking habit. Early treatment or preventive treatment against gonarthrosis is beneficial. Therefore we suggested a simple evaluation method with a quantity of burden impulse of the knee by stabilometers and (3D) acceleration sensors. Subjects wore the (3D) acceleration sensors on their lateral condyle of both tibiae, and "one-step-walk," the stepping on a loading device, was measured. Burden impulses of both knees were analyzed by mass, times, and acceleration, and the difference of impulse between the knees were regarded as a parameter for evaluating the state of the knee. As a result of experiment, it recognized 5.4% difference between the knees.
