C-Brace high-tech KAFO

A leg brace for people living with partial paralysis, spinal injury, post-stroke and post-polio syndrome

Custom electronic leg brace

The C-Brace computer controlled orthosis is an entirely new approach to walking when back injuries or leg muscle weakness limit you. Instead of a locked knee brace—or a wheelchair—imagine a system that gives you the freedom to participate in many daily activities. Walk all day, walk smoother, walk with confidence and greater safety. Ask your Orthotist if the C-Brace is right for you.

Measures your motion

A knee angle sensor built into your orthosis gathers data about your movements so the C-Brace microprocessor can respond to keep your walking stable and secure.

Custom fit to you

A lightweight carbon fiber thigh shell is shaped to fit you.

Fits your form

The shape of the calf shell is based on a cast so it matches your shape.

Adapts automatically

The microprocessor controlled C-Brace, unlike traditional locking knee joint systems, makes sure it is stable when you need it, and swings freely when you are ready to take a step.

Integrated information

The built-in ankle moment sensor captures information and sends it to the microprocessor to be analyzed. The microprocessor uses this information to optimize the resistance of the brace in real time to best support you.



What you need to know

Advantages for you

If your brace doesn’t let you change speeds while walking or put weight on your flexed knee when you sit down, the C-Brace may help expand your activities. Whether you are facing an incomplete spinal cord injury, weakness or paralysis of your quad muscles or post-polio syndrome, the C-Brace was designed to help compensate for the resulting limited mobility.

Del, who wears bilateral C-Braces due to a spinal stroke (embolism), shares his experience wearing the computer controlled orthosis.

“My family and I decided to end our wonderful trip to Orlando, Florida with a trip to Sea World. This particular day would be quite the challenge for myself as well as the C-Braces, but as determined as I am, I am always up for a challenge. I started my day at 7AM and by the time I ended my day it was 2AM –19 hours later! I really put the C-Braces to the test this particular day with all the walking and standing.”

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 stance control section.

Orthotronic—not bionic

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 orthotronics topic page.

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). We’ve developed a series of videos to support you, your Orthotist and Physical Therapist in this process. 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. Ask your Orthotist for more details, and visit our YouTube channel for a preview.

Try it on for size

The C-Brace is custom made for each, unique, wearer—and can even be made to accommodate heavy duty users like Del. 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 your orthotist explain the differences between your current brace and this new, computer controlled orthosis. Share this site with your Orthotist, or contact us for a no-obligation opportunity to explore your options.
