Abstract: This paper presents the task to establish a new and as simple as possible algorithm and method for testing an-kle-foot orthoses (AFO) durability. Finite element analysis of the AFO allowed estimate weak points in the structure of orthosis. It was found that in the spring part of the AFO 1047.8 N loading could cause fracture or crack in its struc-ture. Maximal stresses 249.53 MPa were found at the critical point. Distribution of maximal forces was evaluated in all the dynamic conditions of the experiment. The major force acting on the critical point was identified during the jumps (~ 30 N). It does not exceed and is far from loading limits estimated in static simulation test. Created AFO testing method is sufficient for simple initial assessment.
