2.2 Function
This product features microprocessor-controlled damping of plantar flexion (motion of the foot in
the ankle joint in the direction of the sole of the foot) and dorsiflexion (motion of the foot in the
ankle joint in the direction of the instep).
The microprocessor uses the measurements of an integrated sensor system as a basis to control
a hydraulic unit that influences the damping behaviour of the product.
These sensor data are updated and evaluated 100 times per second. As a result, the behaviour of
the product is adapted to the current motion situation (gait phase) dynamically and in real time.
Thanks to the microprocessor-controlled damping of the plantar flexion and dorsiflexion, the
product can be individually adapted to requirements.
For this purpose, the product is adjusted by qualified personnel using adjustment software.
The product features MyModes for special motion patterns (e.g. cross-country skiing, ...). These
modes have default values configured by the prosthetist using adjustment software, and can be
called up via the remote control or through a special motion pattern (see Page 56).
If configured by the prosthetist, an additional mode "" can also be selected, locking the ankle
joint of the prosthetic foot in its current position.
In case of a system malfunction, safety mode makes restricted operation possible. Predefined
resistance parameters are configured in the product for this purpose (see Page 62).
Empty battery mode permits safe walking when the battery is drained. Resistance parameters that
are predefined by the product are configured for this purpose (see Page 62).
The microprocessor-controlled hydraulic unit offers the following advantages
•
Approximation of the physiological gait pattern
•
Stability while standing and walking
•
Adaptation of product characteristics to various surfaces, inclines, gait situations, walking
speeds and heel heights
