C-Brace Leg Orthosis

Benefits at a glance

New freedom of movement

Walking slowly, quickly, on inclines, or on uneven rough terrain, avoiding tripping situations, going up and down the stairs one foot at a time, step-over-step - all of this is possible with the


Small and lightweight

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

Enhanced safety while walking

The C-Brace enhances safety by analyzing everyday situations in real-time and immediately responding. Due to the real-time adjustments, users can feel safe and secure while sitting down, walking on uneven terrain, and taking the stairs one foot at a time, step-over-step.

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 Orthotist 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 as movement patterns are even more dynamic and responsive.

Simplified fabrication process

The C-Brace can be fabricated by a certified Orthotist at their fabrication facilities. Both the user and Orthotist 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.

  • How can I find out if the C-Brace will work for me?

    To better determine if the orthosis is right for you, you will need an evaluation from a qualified medical professional.

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

    Before you are fitted with a C-Brace, 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. However, your certified O&P professional will provide you with expert advice regarding this.

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

    When you are fitted with a C-Brace, your orthotist will explain the proper use of the orthosis 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.
