What you need to know

Advantages for you

The E-MAG Active electromagnetic stance control orthosis acts as an active walking partner, not just a static support. Even better, it doesn't just come "one size fits all." As part of the fitting and training, your Orthotist will calibrate the E-MAG Active to you and your physical abilities.

When stability matters

Being able to think about your activities – not whether your brace is locked – delivers stability without worry.

With you every step

The E-MAG Active is calibrated to you, and throughout your walking motion – or phase of gait. The sensor integrated into the electronics uses data to unlock the knee joint at the right point of your gait. Learn more about .

Try it on for size

Better body posture

The E-MAG Active makes your movements easier: You may be able to do more again and be more active than before. This can have a positive effect on your muscles and your overall physical health, for example your circulatory system. Thanks to the more natural gait pattern, the need for compensating movements is virtually eliminated, relieving strain on the contralateral side of the body and therefore preventing signs of wear.

Long daily duration of use

Depending on the movements you perform, the E-MAG Active lasts for up to 5,000 steps. This corresponds to about 8 km and is usually sufficient for a day. You can easily charge the battery again overnight.

Quick and quiet

Ongoing operating noises can be perceived as bothersome and unpleasant in many situations. The magnet that unlocks the joint while walking works quickly and quietly, making it inconspicuous in everyday life.
