Benefits at a glance
Walk more naturally
A more natural gait pattern and the desire not to always have to concentrate on movements: These are requirements shared by many orthosis users. Intelligent electronics ensure that you walk more naturally and smoothly. A magnet automatically opens the joint and your hands remain free. You can focus on other things in life that are important to you – your family, ventures or hobby.
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.
When you change the E-MAG Active to unlocked mode using a small button, you can even go cycling, for example on a therapy bike. Other sports activities such as Nordic walking are possible as well thanks to the joint's intelligent control unit.
Suitable for everyday use
With its enclosed design, the E-MAG Active is protected against external influences such as impacts and clothing getting tangled. The joint surfaces form a homogenous, enclosed surface even when the joint is flexed.
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.
The E-MAG Active secures your knee joint at the crucial moment shortly before you reach the stance phase, i.e. in the phase where your weight is supported by the affected leg. Early locking is accomplished by the PreLock function. It releases your knee joint again for the swing phase, which is when you swing your leg. The E-MAG Active is unlocked by your walking movements at every step and locked again before you step down with your foot. This is made possible by an intelligent sensor system, which measures the position of the leg while walking and sends this information to the electronics in the joint. Then the magnet unlocks the joint – quickly and quietly. This is also how the joint was named: E-MAG for electromagnetic.
Your orthopaedic technician designs the orthosis individually according to your needs. The knee joint system is then integrated into this orthosis. In this process, the most suitable design option for you is chosen from numerous possibilities.
The E-MAG Active is approved for a body weight of up to 100 kg. Depending on the weight, it is possible to construct the orthosis so that there is a joint only on the outside of the leg – which makes the orthosis even lighter and more discreet.
Today's components from the computer and electronics industry are so small that they can be integrated in systems very discreetly. This is also the case with the E-MAG Active. You can wear the orthosis under normal clothes and, thanks to the enclosed design, clothing also cannot get caught. The magnet operates very quietly as well.
No, but with the from Ottobock, a waterproof walking aid is available which is designed especially for wet conditions. All of the components used are designed for contact with water.
It is not possible to make any specific recommendation. You must be able to safely control any vehicle for which you require a driving licence and insurance, or which is used in traffic. This ability when wearing an E-MAG Active is determined on a case-by-case basis. You are required to observe national and state laws.
