Patent ID: 11039762

Abstract:
A knee joint dynamic evaluation method for diagnosing human joint diseases by tracking motions of the knee joint includes constructing an evaluation model including a first angular difference threshold α1, a second angular difference threshold α2, and an anterior-posterior displacement difference threshold ε; synchronously collecting a single set of three-dimensional and six-degree-of-freedom movement data of a left knee joint and that of a right knee joint with devices; comparing the three-dimensional and six-degree-of-freedom movement data between the left and right knee joints with a data analyzing device, and calculating differences of the flexion and extension angles, the medial and lateral tilt angles, the medial and lateral rotation angles, and the anterior-posterior displacement movement values of the two sets of movement data; inputting the differences into the evaluation model to obtain the corresponding grading system, which will output the first, second, third, or fourth evaluation level.
