● patients who have problems with the nervous system;
● patients who have renal insufficiency;
● patients who are in pregnancy;
● hemorrhagic;
● epileptic;
● bringer of metal prosthesis;
● patients with thermo dolorific sensibility problems;
● asthenic.
The application is also contraindicated:
● in tumoral focus;
● on the abdomen in all the cases of calculosis or inflammation;
● in the cardiac area for the risk of ventricular fibrillation or syncope;
● in cutaneous zones where there are cuts, punctures, eczemas, etc.
● For the risk of burns because there are zones with low electrical resistance and so concentration of the current in
those parts with increased thermal effect.
NOTE:
Generally the right current’s intensity for the iontophoretic giving is 0,02 – 0,05 mA for cm
2
of used surface elec-
trodes, it must not exceed 0,1 mA for cm

.
The supplied or optional electrodes have the following dimensions and surfaces:
REF
00607.01 DIMENSIONS 80 x 120 mm SURFACE 96 cm

REF
00607.02 DIMENSIONS 45 x 60 mm SURFACE 27 cm

REF
00607.03* DIMENSIONS 120 x 160 mm SURFACE 192 cm

In the application of unidirectional variable currents there can be the presence of histothermic and histochemical effect
similar to the galvanic current.
This effect can be obtained calculating the mean current value that depends on the applied wave form.
For a diadynamic monophasic current the mean value is equal to:
Im = Ip / π
where: Im (mA) is the mean current
Ip (mA) is the max current value
And so:
Im = circa 0,32 Ip
For a diadynamic biphasic current is equal to:
