C-Leg 4

The key to fluid movement is a knee that responds quickly to different inclines and surfaces. With the C-Leg 4, users get improved stance release and increased support for descending ramps and stairs, enabling noticeably smoother and more reliable movement.

Stumble Recovery Plus is active at all times with the C-Leg 4 Update. This ultra-precise feature automatically detects fall-like movements during the swing phase of users’ gait and activates the resistance they need to avoid a fall, recover their balance, and maintain greater stability.

With the manual locking function users can conveniently secure the C-Leg 4 in extension with a simple tapping pattern, even when using a cosmetic fitting. This is particularly helpful during sporting activities, for example.

The C-Leg 4 detects when users sit down, mirroring their speed to keep them stable and in control – even if they’re using a chair or a walking aid for support. Once seated, the user can enjoy a relaxed, comfortable position with a free-swinging joint thanks to the automatic sitting function.

It’s easier than ever for users to get the most out of their C-Leg. Deep sleep mode saves battery during long flights, camping, or other activities where power supply is limited. The charger enables one-handed use. Plus, there’s a USB charging adapter available.

A training function provides a feedback signal after every successful swing phase initiation to support troubleshooting and gait training as users get accustomed to their prosthesis. This feature can be activated and deactivated by the prosthetist or user via the Cockpit app.

C-Leg 4 is now IP 68 and even more durable than before with enhanced protection from the elements. The electronic components of the C-Leg are protected from freshwater submersion up to 3 meters for 1 hour (IP 68). Please note it is not corrosion resistant. This technological upgrade from IP67 to IP68 was made to ensure users enjoy peace of mind in their everyday activities.

Users can easily get more support for their favorite activities. MyMode Plus offers a fantastic selection of options for work, leisure, and athletics. Together with their prosthetist, users can select two settings for easy activation in the Cockpit app or via a movement pattern.

Users can personalize the look of their prosthesis thanks to a new customizable shield cover. Not only do these robust, durable covers protect the C-Leg 4 from environmental factors, wear, and tear, they also now empower users to show off their unique style with each step.

Many of the updates to our signature C-Leg microprocessor knee are based on feedback we received from users and professionals. In fact, that’s why the C-Leg 4 is available in two colors: the original lighter Desert Pearl as well as a darker shade, Midnight Shadow.

With the Cockpit app, users can fine tune MyMode Plus and other settings individually, switch between MyMode Plus options, check their knee’s battery status, set their volume, track their activities, perform a knee joint self-test if needed, and much more — all via their iOS or Android smartphone.

Users can choose between intuitive and deliberate stance with the help of their O&P professional. Intuitive stance uses sensor data to detect whether the user needs support while standing or taking a step, while deliberate stance requires more conscious movements to resume flexion.
