2.2 Function
The product is an orthopaedic technology device that makes everyday activities such as standing
and walking possible or easier for the user. If the user's activity level increases in the course of
use, adjustments are required. Changes will also have to be made if the user's physical condition
worsens and more support from the product is needed.
This product features microprocessor control of the stance and swing phase (SSCO).
The microprocessor uses the measurements of an integrated sensor system as a basis to control
a hydraulic unit that influences the extension and flexion resistance 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 stance and swing phase, the product can be individually
adapted to your needs.
In order to do so, the product is adjusted by the O&P professional using an adjustment app.
The product features MyModes for special motion types (e.g.cycling ...). These are pre-con
figured by the O&P professional using the adjustment software and can be activated using the
Cockpit app (see page31).
In case of an error in the sensor system, hydraulic control or when the battery is empty, safety
mode makes restricted operation possible. Resistance parameters that are predefined by the
product are configured for this purpose (see page33).
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 and walking
speeds
Essential performance of the product
• Stability in the stance phase
