Kinematic evaluation was studied using forceplatform with fuzzy theory. In this report, the movement of center of gravity(C.0.G.) of patients with osteoarthrosis (0.A.) and cerebral palsy(C.P.) was measured. Patients and controls walked on the platform, and the displacement of C.O.G. was calculated by twofold integration of vertical and lateral floor reaction force in one stride. Measuring various values in each displacement and applying fuzzy theory to them, we evaluated walking in patients. This method is useful for evaluating various patients' walking, especially with abnormal balance of C.O.G.
