Handling
Deactivation/activation of prosthesis myo-control (item 1)
Deactivated movement mode
The prosthetic components can be controlled by the user but do not move.
The signal processing and communication functions are active and can be reviewed and
configured in the software by the O&P professional.
INFORMATION
Deactivate movement mode before each initial fitting prior to configuring the myosignals. Activated movement
mode can lead to unexpected motion sequences of the elbow component if the myosignals have not been adjus­
ted.
Activated movement mode
The prosthetic components can be controlled and moved by the user.
The electrode signal curves are shown in the software. Further adjustments can be made
by the O&P professional.
Manual control of the prosthetic components (item 2)
Clicking the button causes the desired movement to be performed. The movement ends after releasing the button.
The prosthetic components move at reduced speed.
Reverse (item 3)
This function makes it possible to reverse the prosthesis movements, for example: open-close, flexion-extension.
Adjusting the working range (item 4)
The coloured bars represent the movement specifications of the prosthesis. The thresholds can be adjusted with
the slider.
7.3.2.11 Starting the electromyography (EMG)
Press the "Start" button to use the EMG function.
Start EMG
Stop EMG
7.3.2.12 Electrode signal boosting
Boosting of the control signal (item 1)
The input signal is digitally amplified. The boosting range can be adjusted between 50% and 400%. The colour of
the slider corresponds to the respective control signal.
Activating signal inputs (item 2)
When the button is activated, the connected control devices are identified. The button colour corresponds to the
respective control signal.
Activating display of the myosignal (item 3)
After clicking the button, the control signals are shown in the MyoGraph. The button colour corresponds to the
respective control signal. The active button is shown with a white background.
Defining switching channels (item 4)
After activating the Switch Matrix, a signal pair can be selected for the switching version.
The Switch Matrix defines the user's preferred control signals (see page 57) for switching.
