Linx has been designed to deliver an experience that mimics the incredible and complex structure of the human leg by actively sensing and analysing data on the user movement, activity, environment and terrain providing a coordinated stream of instructions to the hydraulic support system.

The result is a walking experience that is closer to nature than ever before, giving the user the freedom and confidence to get on with their life.

Precision Performance

Integrated sensors continually analyse data, adjusting the hydraulic technology to seamlessly align the leg for the next step. This integrated and coordinated limb response ensures fast adjustment times and easy navigation of slopes and steps, allowing the user to think about where they are going, rather than how they are going to get there.

Linx - Down Ramps

Down Ramps

Linx delivers controlled ramp descent with different response levels for steep and shallow slopes. The knee and foot work together to optimise the rate of plantar-flexion and dorsi-flexion. The knee resistance is simultaneously adapted by introducing an intermediate resistance. On intermediate ramps, Linx offers a braking effect that secures the whole body for safe descent.

Linx - Up Ramps

Up Ramps

The knee and foot work in unison to dorsi-flex quickly. The toe remains dorsi-flexed for safe and efficient swing-through, while the heel stiffens to support the knee flexion. If stationary on a ramp, the toe will remain in dorsi-flexion to help reduce the extension moment on the knee, allowing a more upright posture for a more comfortable standing position.

Linx - Speed & Terrain

Speed and Terrain

Additional synergies gained from simultaneous knee and foot programming, combined with the optimised control unit and hydraulic system means smoother transitions between speeds, and effortless progression over
varied terrain.

Superior Comfort

Amputees can face health issues long after amputation, with lower limb amputees being 2-3 times more likely to develop osteoarthritis compared to the general population.1

Long term musculoskeletal health depends on the replication of the dynamic and adaptive qualities of natural limb movement, and Linx is the world’s first lower limb prosthesis to incorporate a completely integrated response system to serve this user need.

Linx - Superior Comfort

Exceptional Safety

The varying levels of stance support that Linx provides helps to increase the user’s confidence and independence, reducing the risk of stumbles or falls to help ensure more balanced limb loading for greater long term health and protection. Linx provides optimal stance support, whether walking in a crowded environment, on uneven terrain, slopes, steps or when standing. This unique combination of the integrated stance support and hydraulic technology within Linx contribute to the user’s safety.

Linx - Controlled Stance Support

Controlled Stance Support

Supportive resistance throughout stance phase provides optimal stability for walking with greater safety and less effort on a variety of surfaces.

Linx - Standing Support

Standing Support

Maximum resistance stabilises knee and foot on both flat and sloped terrain, encouraging better posture and balanced loading to relieve pressure on the sound limb and lower back.

Linx - Stumble Recovery

Stumble Recovery

Stance resistance engages during swing phase extension to ensure knee stability, should the user stumble. Under such circumstances the flexion resistance dynamically increases to provide enhanced stumble recovery.

Linx - Dynamic Stair Descent

Dynamic Stair Descent

With immediate support from the first step, knee resistance progressively increases with knee flexion for enhanced control and safety when descending stairs.

Linx - Dynamic Slope Descent

Dynamic Slope Descent

The integrated knee and foot response allows the user to walk leg-over-leg on intermediate slopes.
