The E-MAG Active was developed for users who, due to paresis or a complete failure of the knee extensor muscles, are unable to stabilise their knee joint unassisted.
An intelligent sensor system measures the leg position while walking and controls the orthosis joint accordingly. Therefore the knee joint is unlocked automatically while walking: the leg can swing freely. The PreLock function securely locks your knee joint for the stance phase even if you have not fully extended your leg yet. You can stand safely and walk more naturally with the E-MAG Active.
Even users who have no ankle functionality whatsoever are able to use the E-MAG Active.
Rechargeable battery
The battery can be removed for recharging.
Switching mode
The switch allows the user to change to cycling mode.
PreLock function
The PreLock function already secures the knee joint at 15° of flexion and then locks it for the stance phase prior to full extension.
Medial support
With the use of the medial support, the E-MAG Active can be used with a body weight up to 100 kg.

E-MAG Active – reliable support
Many orthosis users share certain requirements, such as a more natural gait pattern and a desire to not always have to concentrate on their movements. Intelligent electronics ensure that you can 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, activities or hobby.
The E-MAG Active makes your movements easier: You can 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 symptoms of wear.
After changing 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.
Its enclosed design protects the E-MAG Active against external influences such as impacts and clothing getting caught. The joint surfaces form a uniform, enclosed surface even when the joint is flexed.
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.
Continual operating noises can be perceived as bothersome and unpleasant in many situations. The magnet works quickly and quietly when unlocking the joint during walking, making it inconspicuous in everyday life.
Trust yourself again
Beatrix tells her story
Beatrix was run over by a concrete mixer at the age of 13 and has been living with incomplete paraplegia ever since. Thanks to her strong will and her E-MAG Active/Nexgear Tango orthosis, she has literally managed to get back on her feet and is no longer permanently dependent on her wheelchair.
Moving confidently with sensor control
Functionality
The E-MAG Active secures your knee joint at the crucial moment shortly before you reach the stance phase. In other words, 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.

Answers for you
How can I get an E-MAG Active?
Your doctor and your certified O&P professional can advise you in detail whether an E-MAG Active is suitable for you.
How is the E-MAG Active integrated into my orthosis?
Your O&P professional 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.
Up to what body weight is the E-MAG Active approved?
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.
Can I wear the E-MAG Active under normal clothing?
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.
Can I shower with the E-MAG Active?
No, but Ottobock’s Aqualine orthotic system is a waterproof walking device designed especially for wet conditions. All of the components used are designed for contact with water.
Can I drive a car with the E-MAG Active?
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.
