Abstract
A rotation damper for toggle joints prosthesis (1) that is arranged for swing phase control of the prosthesis, and incorporates a housing having at least one clamber (13) with a damping medium disposed therein is disclosed. The chamber is arranged so that the damping medium is displaced through a restriction (14a) with a swing motion of at least one pivot axle (6) in the prosthesis. The damping medium is a visco-elastic compound, having an ability to exert a bigger resistance at rapid motion processes as compared to slower processes.
