Recommendation: With adjustment core on both sides Polycentric With mechanical extension assist Suitable for max. 100 kg body weight
For trans-femoral amputees With moderate functional levels Medium stance and swing phase stability Not Suitable for amputees with higher functional levels
Description: Upper and lower joint section is connected with linkage bars. The stance phase stability is achieved with the polycentric kinematic (adjustable of the instant center of rotation by adjustment of the stop). The step-less adjustment of the axis friction and of the extension assist spring controls the swing phase.
