The E-MAG Active knee joint system combines mechanics and electronics in order to maximise mobility, safety and reliability.

The E-MAG Active is the first electronically controlled knee joint system with a secure stance phase and free swing-through phase controlled independently from the ankle or sole of the foot. An intelligent sensor system measures the leg position while walking and controls the orthosis joint accordingly. This means that the knee joint is automatically opened and closed while walking; it locks in the stance phase and unlocks in the swing-through phase.
The advantage: Even if you have no ankle functionality whatsoever, you are able to take advantage of the features offered by this orthosis joint. The E-MAG Active facilitates a more natural, smoother gait pattern and therefore improves your quality of life.
The E-MAG Active is also suitable for you if you have previously not received or refused an adequate orthotic fitting for various anatomical reasons, e.g. poliomyelitis, post-polio syndrome or incomplete paraplegia with certain physical conditions.
The E-MAG Active was developed specifically for patients who, due to partial paralysis or a complete failure of the knee extensors, are unable to stabilise their knee joint without compensating measures.
Safe use of the E-MAG Active knee joint system requires certain residual muscle functions or hyperextension of the knee joint. This guarantees consistent activation of the swing-through and stance phases.
The E-MAG Active knee joint system is suitable for a body weight of up to 85 kg.
