[0150] Example: Select a healthy male as a subject, with a height of 171cm, a weight of 55.2kg, and no major diseases. The subject is required to perform a walking experiment. For specific scenarios, see Image 6 . The subjects walked on the three-dimensional force-measuring treadmill at a speed of 1.2m / s for 1min, and the subjects' right leg vastus lateralis, semitendinosus, long head of biceps femoris, and medial head of gastrocnemius were collected synchronously. Surface electromyographic signals, and simultaneously collect the three-dimensional coordinate information of the marked points of the hip joint, knee joint, ankle joint and the outer center of the foot of the subject's right leg, as well as the three-dimensional interaction force between the subject's right foot and the force-measuring treadmill . Utilize these data to carry out the verification of knee joint moment test method of the present invention, test result sees Figure 7 .
