Wrist joint range of motion as an implicit curve could be approximated by the polynomial function using 3L algorithm. In this paper we discuss how different factors, such as inclination and width of the ribbon surface (distinguishing feature of the 3L algorithm) and addition of positional control points, affect the quality of such approximation. We also address the question of optimal amount of those points. Results shown that that the right choice of those factors increases the quality of the approximation.
