This makes everyday activities such as sitting down, walking on slopes and even climbing stairs possible again.

The C-Brace® consists of a thigh, lower leg and foot part, which are all individually manufactured. An ankle joint (unilateral or bilateral fitting) or an individual spring element connects the foot part to the lower leg part.


The C-Brace® leg orthosis from OttoBock is a computer-controlled orthosis that offers the user unprecedented freedom of movement. The new sensor technology makes the entire movement process even more dynamic and sensitive, allowing the user to make adjustments to their joint via smartphone app. Theapp also lets you switch between different modes, such as bike mode, to further customize the experience.


Motor fine tuning


Adjustment of a physiological gait pattern in the stance and swing phase.

The C-Brace® consists of individually fabricated femoral, tibial and foot components connected by an ankle joint (unilateral or bilateral fitting) or an individual spring element.

With the C-Brace® joint, you can optimize your gait and the performance of different hurdles in everyday life.

C-Brace® thus recognizes which phase of walking the user is in. It can regulate the hydraulic resistances and control the flexion and extension of the knee.

Freedom of movement


Walking slowly and quickly, walking on slopes or uneven terrain, avoiding tripping situations, walking down stairs in alternating steps, or bending the leg under load.


Extremely inconspicuous


The new C-Brace® is small so that it can be worn inconspicuously, even under clothing. It is lightweight so that the user requires less force when walking.




C-Brace® reacts in real time, which provides safety, even in possible tripping situations: The user can step and sit with the knee bent, walk on uneven terrain and on slopes.


App control


Users can conveniently control their C-Brace® using the Cockpit App, e.g. when switching to cycling mode.


Before you can go it alone, there is a three-step plan:


  • Training without orthosis
  • Training with orthosis
  • Individual gait training with the orthosis

The therapy exercises, which are performed without an orthosis, are mainly aimed at improving mobility and muscle strength.


  • Bending under load
  • Sit down
  • Stair climbing
  • Ramps

The benefits of training:


  • Individual operating modes adjustable by orthopedic technician
  • A natural posture is worked out in therapy and can thereby reduce one-sided physical overload and resulting damage
  • Reduced effort compared to locked orthoses
  • Increased sense of security and newly experienced mobility increase quality of life
  • Strengthening of previously little used muscles
  • Reduction of muscle atrophies
  • Contractures and immobilization-related joint damage can be avoided
  • Cardiovascular performance is maintained for everyday activities
How does the C-Brace work?

The abbreviation SSCO® stands for Stance and Swing Phase Control Orthosis and means that both the swing and stance phases of walking are controlled by the orthosis. SSCO® is the solution for people with paralysis symptoms.

The C-Brace® is a revolutionary new orthotic device that can help you regain your mobility and independence. The C-Brace® uses advanced sensor technology to provide real-time feedback and support to help you move freely and confidently. Whether you walk, run or ride a bike, the C-Brace® can help you stay active and mobile. With the C-Brace®, you can experience many new ways to move! For example, when you swing your leg forward, the cushioning decreases, and when you stand, it increases so that you can assume a natural, slightly bent posture with your leg.

FAQ - Frequently asked questions

How do I find out if C-Brace is right for me?

Let us advise you!

Is the c-brace health insurance subsidized?

Yes it will. Talk to us.

Can I test the orthosis beforehand?

Before you are fitted with a C brace® orthosis, your certified orthopaedic technician can use a diagnostic test orthosis to find out whether you are able to use the functions of the c brace ottobock for yourself.

How long will it take before I can go with the c brace otto bock?

This depends on your prerequisites and the therapy. We do not want to make a recommendation here based on incorrect assessments.

How do I learn to use the C-Brace®?

Training and adjunctive therapy are part of every care.

Can I shower with the C-Brace® orthosis?

The orthosis is not waterproof. Showering is not possible. However, with the Aqualine orthosis system from Ottobock, there is a waterproof walking aid that is specially designed for the conditions in wet areas.

Do the size and weight of the orthosis have a bad influence on the gait pattern?

Although the orthosis is heavier than normal systems, studies have ruled out any adverse effects.

How is walking changed?

Walking is reinforced in real time, which provides safety. The orthosis can react quickly due to the sensors. Your movements become more natural and rounded.

Can I wear the orthosis over my pants?

In principle, yes. However, the pants should then fit tightly so that they do not wrinkle and cause pressure points. Most patients wear the orthosis directly on the skin.

Can drive a car with the C-Brace?

Driving a vehicle with an orthosis depends on the respective national regulations... The orthosis-supplied leg must not interfere with the control of the motor vehicle (e.g. operation of accelerator and brake). However, there are other possibilities, such as retrofitting the car e.g. with hand controls.

What shoes do I have to wear?

In principle, you can wear all shoes. However, the orthopaedic technician will adjust the C-Brace® to a heel height that you should then maintain. Under certain circumstances, you will use one size more than before in order to have enough space for the foot part.

And without shoes?

The risk of slipping with the foot part would be too great. In addition, the heel height would change as a result.

How often do I have to charge the C-Brace®?

You should load the orthosis daily.

And when the C-Brace is empty?

An advisory tone warns you beforehand. After that, the orthosis goes into a safety mode. Here it maintains a certain damping. The technician determines this together with you in advance.

What else can I use the orthosis for?

You can have another mode set, for example for cycling. You can control the second mode via the app.

Do I have to pay attention to anything when storing the orthosis?

The c-brace orthosis system should be stored upright to prevent air from accumulating in the hydraulics.

Who is the Ottobock C-Brace suitable for and who is it not suitable for?

The c-brace indications:

In principle, the C-Brace® is suitable for all neurological indications of the lower extremities. First and foremost, these are incomplete paraplegia (lesion height between L1 and L5) with very little or no spasticity as well as the condition after poliomyelitis, post-polio syndrome and multiple sclerosis. Important here:

  • The patient must be able to fully stabilize the trunk and stand freely
  • The muscle strength of the hip extensors and flexors must allow a controlled swing through of the affected leg
  • Compensation by means of hip swing is possible

Contraindications & for whom it is not suitable?

  • Flexion contracture in the knee and / or hip joint over 10°.
  • Knee varus / valgus malalignment above 10
  • Moderate to severe spasticity
  • Leg length difference over 15 cm
  • Orthoprosthesis / Dysmelia
  • Body weight over 125 kg

Exact indications:

  • Unilateral or bilateral leg paresis or flaccid paralysis caused by e.g. post-polio syndrome, traumatic paresis incl. paraplegia
  • The decisive factors are the physical conditions, such as muscle status, joint mobility and possible axis deviations, which must ensure safe control of the orthosis
  • Users must meet the physical and mental requirements for the perception of optical/acoustic signals and/or mechanical vibrations
  • The existing muscle strength of the hip extensors and flexors must allow controlled advancement of the lower extremity (compensation by means of the trunk is possible). Passive flexion of the knee joint must be possible.
  • Cbrace in MS is also possible
