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, they can enjoy a relaxed, comfortable position with a free-swinging joint thanks to the supported 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.

With the C-Leg 4, users don't have to worry about occasional water splashes. Whether they’re walking past a sprinkler, working in the garden, or caught in a sudden rain shower, the C-Leg is designed to stay protected as long as the joint and components are dried off afterward. The C-Leg is NOT WATERPROOF.

Now, users can easily get more support for their favourite 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 personalise the look of their prosthesis thanks to a new customisable shield insert. Not only do these robust, durable covers protect the C-Leg 4 from environmental factors or 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.

The app connectgo.pro for Android and iOS smartphones and tablets makes it easy for O&P professionals to quickly and conveniently program the C-Leg for their users.
