What you need to know

Advantages for you

Out of her wheelchair

Christin depends on her C-Brace to measure and respond to her movements – even when she’s out searching for new horizons. On rough terrain, Christin can depend on the C-Brace to help keep stumbles from turning into falls. To learn more about gait, read our page Stance Control Orthotics Explained.


If crowds and unpredictable sidewalks and floors can challenge you, the C-Brace can help make your journey a little smoother. Changing speed and direction is easier when you can put weight on a bent knee. And, the idea of “orthotronics” means you have the combination of electronic and mechanical systems working together to support your every step. To learn more, visit our page The Future: Orthotronic Mobility Science.

Walk with confidence again

The C-Brace is a new approach to walking, and it will take some time to re-learn the motions of walking (gait). The people who have benefitted the most from this advanced orthotic have taken the time to learn to trust that the C-Brace will respond when you need it – and to get back to a normal walking pattern. To find out if the C-Brace is suitable for you, please book an assessment at one of our clinics.

Custom made to you

The C-Brace is custom made for each unique user - and can even be made to accommodate heavy duty users. But with our C-Brace diagnostic tool - which can be adapted to most legs - you can try out C-Brace support for yourself. The diagnostic tool helps us to explain the differences between your current brace and this new, computer controlled orthosis. To find out more about the C-Brace or to book an assessment, please contact one of our clinics.
