NK-6 Symphony Knee

The NK-6 Symphony has a unique 6-Bar polycentric structure, providing a high level of stability in the stance phase. Its innovative mechanical sensor, the p-MRS system, automatically detects the walking status from the position of the centre-of-mass and controls the stability of the knee joint accordingly. A hydraulic cylinder provides a smooth swing phase, and works with the NK-6’s adjustable stance flexion features to enhance walking and provide a comfortable, confident gait to the user.

Features and benefits

• p-MRS (Polycentric-Mechanism of Reaction force Sensing system) supports knee stability by monitoring the underfoot position of the ground reaction force, anticipating and adjusting the user’s movement.
• Adjustable stance flexion prevents sudden knee buckling and reduces centre-of-gravity displacement.
• Hydraulic cylinder reduces initial knee flexion resistance and energy consumption.
• Optional selective lock provides maximum stability whenever needed.
• Suitable for medium to high activity levels.
• Independent flexion and extension resistance adjustment.
