New freedom of movement

Walking slowly or quickly, running on inclines or in rough terrain, avoiding tripping situations, walking down stairs step-over-step or flexing the leg under a load: the C-Brace® lets users experience new freedom of movement.

Small and lightweight

The new C-Brace® is small enough to be worn inconspicuously under clothing. Because it’s lightweight, the user expends less effort while walking.

Enhanced safety while walking

The C-Brace® enhances safety by responding in real time, including in possible tripping situations: the user can step or sit down with the knee flexed and walk on uneven terrain or slopes.

App control for user and technician

Users can conveniently control their C-Brace® with the Cockpit app, for example when switching to cycling mode. The O&P professional uses the Setup app to individually adjust the C-Brace® in simple steps.

Dynamic movement patterns

The new sensor technology makes the C-Brace® even more intuitive to use; movement patterns are even more dynamic and responsive.

Simplified fabrication process

The new C-Brace® can be constructed by certified O&P professionals directly at the medical supply company. Both the user and technician benefit from simplified fabrication.


The C-Brace® consists of individually fabricated thigh, calf and foot components. An ankle joint (unilateral or bilateral fitting) or an individual spring element connects the foot and calf components. The sensor system continuously measures the flexion of the knee joint and its angular acceleration. This lets the C-Brace® detect the user’s current walking phase, so it can regulate the hydraulic resistances as well as control the flexion and extension of the knee joint.

User experience

Portrait of C-Brace user Hannah.

In conversation with Hannah

Hannah remembers that doctors actually advised her to have her paralysed leg amputated. It’s unbelievable when you consider how independent she is in her day-to-day life with her family now. “I can walk again, and I now feel free to do all the things I did before my illness,” Hannah says. And as a mother, the most important thing for Hannah is being able to hold hands with both of her children.

In conversation with Melvin

Melvin talks about the first time he wore the C-Brace®. “It was a great feeling when I noticed how the C-Brace® supported me,” Melvin says. He can rely completely on the C-Brace®, lead a more flexible everyday life and simply get going when wants to – without planning and considering whether it will be too much for him.

In conversation with Wolfgang

Without the support of the C-Brace®, Wolfgang would be unable to support his own weight. He would collapse. He says he is fascinated about everything that’s possible with this orthosis. “I have tried to outsmart the C-Brace® before, but it was impossible. I can go up and down stairs, or walk across meadows and on rough trails,” he says. Wolfgang has yet to discover the limits of the C-Brace®.

  • How can I find out whether the C-Brace® is suitable for me?

    The C-Brace® is suitable for a wide range of neurological indications. However, a detailed anamnesis – that is, an examination by a doctor or O&P professional – is required on a case-by-case basis in order to determine whether the C-Brace® is actually appropriate.

  • If a C-Brace® is generally an option for me – can I test the orthosis first?

    Before you are fitted with a C-Brace® orthotronic mobility system, your certified O&P professional can use a diagnostic trial orthosis to determine whether you are able to use the functions of the C-Brace®. Please talk to your O&P professional, and he or she will advise you in detail.

  • How long does it take to learn to walk with the C-Brace®?

    Many different factors determine how soon you can walk with the C-Brace® and whether you are capable of exploiting its full functionality. As always, your personal physical condition is an important factor here. However, your certified O&P professional will provide you with expert advice regarding this as well.

  • How do I learn to use the C-Brace®?

    When you are fitted with a C-Brace®, your technician will of course explain the proper use of the orthosis to you in detail. In the course of special training and exercises, you will learn everything you need to know in order to use your C-Brace® to its best advantage.

  • Can I shower with the orthosis?

    The C-Brace® is not suitable for showering. However, Ottobock’s Aqualine orthosis system is a waterproof walking device designed especially for wet conditions. All of its components are designed for contact with water.
