Such prostheses are characterized by high\nstability during the stance phase of the movement. The existing\nvariety of polycentric mechanisms indicates the possibility of finding\nthe optimal prosthesis design satisfying several quality criteria.In this\npaper we present a multicriteria method for the synthesis of the\nartifical polycentric knee mechanism based on the uniform systematic\nstudy of the design parameters space and on the analysis of Pareto\noptimal solutions.","references":"[1] D.
