The four elbow-forearm assemblies ErgoArm®, ErgoArm® plus, ErgoArm® Hybrid plus und ErgoArm® Electronic plus simplify myoelectric fitting of higher amputation levels.


The higher the amputation level, the greater the demands on the fitting technique. The two ErgoArm® Electronic plus and ErgoArm® Hybrid elbow-forearm assemblies facilitate myoelectric fitting of high amputation levels.
They offer up-to-date technology with the aim of combining low weight and extraordinary function with appealing design. The 12K44 ErgoArm® Hybrid plus is recommended for hybrid protheses with a myoelectric hand and a cable- controlled elbow joint. Due to the integrated "EasyPlug" cable guide, all electric cables disappear inside the prosthesis so that they are inconspicuous and protected.
Due to its electronically-controlled lock, the 12K50 ErgoArm® Electronic plus can be locked or unlocked with myo-signals as well as with a switch. This happens inconspicuously in fractions of a second and offers reliable loading in any position.
