8 Control Options and Adjustment of the Electrodes
The best possible function of the prosthesis is achieved through optimal adjustment of the elec-
trodes. This is easy with the MyoBoy.
8.1 Dynamic Mode Control
green coding plug = left Electrohand
blue coding plug = right Electrohand
Opening and closing of the Electrohand 2000 is controlled by two 13E200 Electrodes.
Grip speed and grip force are determined by the level of the muscle signal.
This provides a more natural gripping movement and gentle handling of small, fragile objects
is enhanced.
Adjusting the Electrodes
Select the desired program version in the PAULA program. Adjust each electrode so that the
patient can maintain the muscle signal for approximately two seconds at a point slightly above
the value HIGH (Fig. 6).
8.2 Dynamic Mode Control – „Low / Input"
yellow coding plug = left Electrohand
violet coding plug = right Electrohand
In this mode, maximum grip speed and grip force are reached more quickly. This control should
be used only for children with a low muscle potential (below 20 µV).
Opening and closing of the Electrohand 2000 is controlled by two 13E200 Electrodes.
The grip speed and grip force are controlled by the level of the muscle signal.
This provides a more natural gripping movement and gentle handling of small, fragile objects
is enhanced.
Adjusting the Electrodes
Select the desired program version in the PAULA program. Adjust each electrode so that the
patient can maintain the muscle signal for approximately two seconds at a point slightly above
the value LOW (Fig. 7).
8.3 Digital / EVO 1 (Electronic Voluntary Opening)
white coding plug = left Electrohand
red coding plug = right Electrohand
Two-electrode control –Digital– (only in combination with 9E370 4 in1 Controller LS)
Opening and closing of the Electrohand 2000 is controlled by two 13E200 Electrodes.
When sufficient muscle signal is generated, the Electrohand opens and closes at a constant speed.
One-electrode control –EVO 1– (only in combination with 9E369 4 in1 Controller LS)
The EVO mode has been developed to facilitate control of the Electrohand for children who
cannot differentiate between two muscle signals.
Opening and closing of the Electrohand 2000 is controlled by only one 13E200 Electrode.
When sufficient muscle signal is generated, the Electrohand opens at a constant speed, and
when the myo-signal stops, the Electrohand closes at a constant speed. The electrode is usually
placed over remnant extension muscles.
If this is not practical, the Electrohand can be controlled by any other available myoelectric signals.
The electrode cable must be plugged into the electrode connector plug 1 or 2 of the 4 in1 Con-
troller LS.
