In treatment description, recommended intensity levels are indicated.
N.B. Recommended current levels are just an indication.
NOTE: It is not necessary to set the intensity value (in mA) in Microcurrent programs,
since it has already been set for all the phases.
Open circuit
This device includes a controlling device of power emissions. If the operator increases
the intensity level above 10 mA and the circuit is open (cables are not connected to the
device and electrodes are not applied to the skin), the electrostimulator immediately
resets the intensity to 0 mA.
Therefore, before starting a program, make sure that the cables are connected to the
device and that the electrodes are placed on the area to be treated and that they are not
worn, as this could decrease their conduction capacity. NOTE: Use Microcurrent
programs only on channels 1 and 3 with the gray cables supplied. If the cables are not
connected or they are of the wrong type, the program will not start. Check the cables and
the connections.
Tens
Transcutaneous Electrical Nerve Stimulation (TENS) is a selective stimulation of the
large fibers of the peripheral nerves favoring the closing of the gate entrance for the
pain pulses and increasing the release of endorphinic substances, reducing in this way
the pain intensity. Therefore TENS is particularly indicated to treat the severe and
chronic pain caused by the main musculoskeletal disorders.
TENS currents reduce pain thanks to the following factors:
a. Gate control theory
b. Endorphin secretion
c. Different sedative effects related to frequency
Gate theory
If the electrical signals that lead to the brain information about pain are stopped, also
the perception of pain is eliminated. For instance, if we hit our head against an object,
the first thing we do is massaging the traumatized area. In this way we stimulate the
receptors of touch and pressure. TENS in continuous mode and frequency modulation
can be used to generate signals similar to those of touch and pressure. If their intensity
is enough, their priority is so high that it prevails on the pain signals. Once the priority is
obtained, the gate related to the sensory signals is opened and the pain gate is closed,
thus impeding the passage of these signals to the brain.
