NK-6 Symphony

Features and benefits

• 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
