total stimulation time = fade in + du fade out
Figure 21: Timing chart of current during tDCS
The following table summarizes the available parameters for stimulation waveform mode
tDCS:
minimum value increment maximum value unit
current 250 250 2000 µ A
duration 30 30 1800 s
fade in 0 1 120 s
fade out 0 1 120 s
If the stimulation current is below 150 µ A the impedance check does not work
correctly because of technical reasons. A long fade in value leads to a current
below 150
µ A for several seconds and most time stimulation is canceled.
Experienced data show that current changes of 0.5 mA per second do not
provoke pain for the patient.
STIMULATION
This menu is used to start the stimulation.
The stimulation parameters have to be set in the main menu PARAMETER or fixed in the
active setting.
In the main menu STIMULATION the display show following items (Figure 22):
