FUNCTION
The device automatically adjusts its behavior to activities such as standing, walking, and descending stairs/ramps.
Standing
Whenever stance is detected the device locks and provides the user with full support. This allows the user to take
small steps more naturally without having a locked knee feeling.
Walking
The device supports the user whenever ground contact is detected, releases as swing initiates and provides swing
phase resistance allowing the user to achieve comfortable and symmetric transitions at a wide range of speeds.
The device reduces the perceived exertion and thereby allows for walking longer distance.
Sitting down
As the user leans back to sit down the device responds to proportional loading to support sitting down with a
natural movement.
Descending stairs and ramps
The device flexes and supports the user while lowering to the next step. It is recommended to lean slightly
backwards as this facilitates the prosthetic knee bending and, in case of loss of balance, prevents the user from
falling forward.
