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 indi­
vidually adapted to the needs of the patient.
For this purpose, the product is configured with the "M-Soft" adjustment software.
The product features MyModes for special motion types (e.g. golf ...). These have default values configured using
the adjustment software and can be accessed via the Cockpit app or using a special motion pattern (see page 66).
