By restoring lost muscle function, instead of joint mobility alone, the POWER KNEE™ manages to restore the functionality lost after amputation like no other prosthetic knee system that has gone before.
The natural and carefree mobility its users are empowered with has significant implications in terms of reducing strain on the rest of the amputee’s body and the physical effort required for activity.
Powered stance: By replacing concentric muscle activity of the quadriceps, the POWER KNEE can lift the user when standing from a seated position; support the user while ascending inclines; and power them up stairs.
Powered swing extension: With an active pendulum motion – swinging forward when the user walks – the POWER KNEE restores walking dynamics during each step; propels the user forward; and enhances pelvic rotation for a more natural gait.
Active heel rise and knee flexion: On level ground as well as on changing terrain, the POWER KNEE actively lifts the heel off the ground. The result is sufficient toe clearance during swing which prevents stumbling and improves user safety.
Artificial proprioception: the POWER KNEE anticipates and responds with the appropriate function required for the next prosthetic step; and monitors gait symmetry to stimulate highly efficient gait.
