C-Brace® orthotronic mobility system with Sensor Ankle

The world's first mechatronic SSCO® system

New freedom with the Sensor Ankle

The C-Brace® orthotronic mobility system is suitable for users with paresis or paralysis of the knee extension musculature.

In the past, paralysis orthoses were limited to locking and unlocking the knee joint. Ottobock is offering a groundbreaking system with the C-Brace®. Thanks to an integrated microprocessor, it responds intelligently to the user's changing situations – in real time. The hydraulic resistances in the stance and swing phase are regulated accordingly. As a user, you no longer have to pay attention to each and every step you take. Walking can become natural again – whether fast or slow, on uneven ground or slopes.

The C-Brace® with Sensor Ankle provides new freedom:

  • It makes a more natural heel strike and more natural rollover possible. The O&P professional individually adapts the range of motion.
  • Slimmer orthosis design

Sensor Ankle

The system ankle joint with integrated sensor screw enables a softer heel strike and more fluid rollover of the foot.

Control buttons

The integrated control buttons are used to select the desired mode.

Lower leg shell

The lower leg shell is made of fibre-reinforced prepreg. A clamp adapter for the spring element or the connection to the Sensor Ankle is integrated as well.

C-Brace® joint unit

A battery and the microprocessor are integrated in the joint unit. The microprocessor processes the sensor signals and controls walking with the C-Brace® in real time. The knee angle sensor measures the current position of the joint every 0.02 seconds.

Foot component

The foot component is made of fibre-reinforced prepreg.

Thigh shell

The custom thigh shell made of fibre-reinforced prepreg guarantees maximum stability with minimum weight.



Benefits at a glance

New freedom of movement

Walking slow or fast – even on inclines or rough terrain – avoiding possible tripping situations, walking down stairs step-over-step or flexing your leg under a load, for example when sitting down: you can experience new freedom of movement with the C-Brace®. With the microprocessor-controlled stance and swing phase, the entire gait cycle can be controlled dynamically and in real time. The system responds instantly to any situation.

Enhanced safety while walking

The C-Brace® recognises the user's current movement phase. Conventional systems only offer two options: locked – the leg is extended under load – or unlocked during the swing phase. The C-Brace® responds in real time. You can take a step with your knee flexed, just like walking naturally, or you can sit down. This makes you safer, especially on uneven terrain, on slopes or in possible tripping situations.

Be active in your free time

Driving a car, or taking a relaxed bike ride with your family: Are these things you find impossible now? The C-Brace® enables a wide range of activities. Your technician configures individual operating modes as needed, such as cycling, which you can then easily select using the control button on your C-Brace®. Get out and about more and enjoy activities that were previously possible for you only with restrictions.

Independent and mobile

You no longer have to permanently concentrate on your orthosis and your next step. Plan your activities according to what you like, take in your surroundings and the people around you again – the C-Brace® makes you more independent and mobile.

Natural body posture

Walking is more relaxed with the C-Brace®. Compared to conventional systems, the C-Brace® can reduce physical exertion while walking and alleviate excessive one-sided strain.

Functionality

The C-Brace® orthotronic mobility system is the world's first mechatronic SSCO® system. SSCO® – Stance and Swing phase Control Orthosis – means this is the first system to control both the swing phase and the stance phase – and therefore the entire gait cycle. The system responds intelligently to changing situations.

The orthosis system mainly consists of individually fabricated thigh, calf and foot components. The unilateral system ankle joint with integrated sensor screw (Sensor Ankle) connects the calf shell to the foot. The sensor screw records the ankle moment and transmits the signal to the microprocessor-controlled hydraulic knee joint unit. This in turn is embedded in the carbon fibre frame together with the electronics. Here the knee angle sensor continuously measures knee flexion and the angular acceleration of the knee joint, i.e. whether the user is walking slowly or fast and taking short or long steps.

This is how the C-Brace® orthotronic mobility system continuously recognises which walking phase the user is currently in. It can therefore regulate the hydraulic resistances and thereby control the flexion and extension of the knee joint.

FAQ

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

    The C-Brace® is suitable for numerous neurological indications. However, a detailed anamnesis is required on a case-by-case basis, i.e. an examination by a doctor or orthopaedic technician, in order to determine whether the C-Brace® is actually suited.

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

    How soon you can walk with the C-Brace® and whether you are capable of exploiting the full functionality depends on many different factors. Your personal physical condition is always important here. Once again you can count on expert advice from your certified orthopaedic technician.

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

    When you are fitted with the 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 move with the C-Brace®.

  • Can I shower with the orthosis?

    The C-Brace® is not suitable for showering. With the Aqualine orthosis system from Ottobock, a waterproof walking aid is available which is designed especially for wet conditions. All of the components used are designed for contact with water.
