NK-6 Symphony
The NK-6 Symphony Knee 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 feature to enhance walking and provide a comfortable, confident gait to the user.
Features and benefits
p-MRS system
- Polycentric-Mechanism of Reaction force Sensing system
- Anticipates and adjusts to user's movements by monitoring the underfoot position of the ground reaction force
- Prevents knee instability from heel-strike to mid-stance by locking knee geometrically
- Naturally and smoothly releases from locking during pre-swing for transition into the swing phase
Adjustable stance flexion
- Absorbs shocks at the heel-strike
- Instantly locks to prevent sudden knee buckling while allowing slight flexion
- Reduces centre-of-gravity displacement
Hydraulic cylinder
- Eases the initiating swing, reducing initial knee flexion resistance
- Decreases energy consumption compared to conventional hydraulic knee joints
Optional selective lock
- Provides maximum stability whenever needed
- Prevents knee buckling, whilst still allowing stance flexion in the lock mode
