Because the world isn't flat.

Linx is the first fully integrated, microprocessor controlled, lower limb system available in the world. Every element is part of a design whole that balances energy, posture and sensation for a truly captivating walking experience. The revolution is the master controller that coordinates the Linx response so the different parts work together in harmony. 




Key features

Linx is unique thanks to enhanced benefits from the precise integration between foot and knee control. The Situational Awareness system updates in real-time and Linx is always calculating safe stance and motion response.

Standing lock

When standing with the knee locked, the user can achieve foot-flat, with the Linx foot in either plantar or dorsi-flexion. This increases safety and reduces the effort required when standing throughout the day. Comfortable and secure standing also encourages good back posture, and the lock simply comes off on toe-load or by movement of the prosthetic foot.

Speed & Terrain

The additional synergies from simultaneous knee and foot programming, along with the optimized control unit and hydraulic system mean smoother transitions between speeds and seamless progression over varied terrain.

Up ramps

The knee and foot work in unison to dorsi-flex quickly. The foot is maintained with the toe up for safe and efficient swing-through going up ramps, while the heel stiffens to support the knee flexion. If stationary on a ramp, the toe will remain in dorsi-flexion to reduce the extension moment on the knee, allowing an upright posture and comfortable spinal position plus standing lock comfort.

Down ramps

Linx delivers controlled ramp descent with different response levels for steep and shallow slopes. The knee and foot work together to optimize the rate of plantar-flexion initially for a stable base, and then increases the dorsi-flexion and knee resistance. On intermediate ramps, Linx offers a braking effect that secures the whole body for safe descent.

Sitting comfortably

Linx supports the body weight to control descent onto a seat. The foot dorsi-flexes and naturally folds away so it can be tucked safely under a chair in crowded spaces, like on the morning commute to work. If sitting with Linx extended, the foot plantar-flexes in a more natural attitude.

Synchronized setup

The synchronized programming for Linx ensures the compatibility of settings for the knee and foot. This means better consistency of dynamic and static operation across all terrain and operation modes. It also allows your clinician to check the operation of your Linx with the live screen data to find the perfect settings for you.

Single programming interface

One screen, whole system programming means your clinician can be guided through the setup and can gain better control of the parameters they are selecting for your Linx. They can see how the knee and foot operate together and the impact that adjusting one has on the other. User programmable selections can also be discussed, planned and programmed.

Battery & charging

With one connection point, charging your Linx couldn’t be easier. The typical battery life for Linx is 3 days, which greatly extends the activity period from that of existing systems. Battery life can be extended by switching the limb off at night or when it’s not required.
