WHY DO I WANT IT?

What is True Variable Cadence?

Every day, every minute we may decide to walk slow, fast, faster and even run. This means that we need to be able to walk/run at different "cadences" (or speeds). Our body naturally adjusts instantly to these different cadences. For an Above Knee amputee to enjoy the same freedom, he needs a knee that instantly & reliably adjusts to these diverse speeds: A True Variable Cadence knee! Many prosthetic knees claim to provide variable cadence, very few deliver consistently.

How does it work?

Today, it is universally recognized that only a knee with a pneumatic and/or a hydraulic fluid control can provide True Variable Cadence. Even a knee with the most advanced microprocessor needs such a fluid control.

Beware of imitations!

Do not automatically assume that a knee with hydraulic or pneumatic fluid control can provide all desirable speeds of walk/run. Many provide only a fluid friction control (walks only at one speed) which helps control flexion resistance without providing "True Variable Cadence". Again, the most advanced microprocessors with fluid control may allow for only a very limited variation in speed.
