modify these levels according to his/her personal needs.
- Moderate intensity. The muscle does not tire, not even during prolonged treatments. The con-
traction induced is tolerable and pleasant. This is the first level on the graphic representation of
intensity.
- Intermediate intensity. The muscle is visibly contracted but the stimulation does not cause the
joints to move. This is the second level on the graphic representation of intensity.
- Elevated intensity. The muscle is contracted substantially. The muscular contraction will cause
the extension or bending of the limb if this is not blocked. This is the third level on the graphic
representation of intensity.
- Maximum intensity. The muscle is contracted maximally. This is an intense treatment that should
be performed only after having executing different applications at lower.
In the descriptions of the treatments, the best levels of intensities are recommended.
NOTE: The recommended levels of current are only indicative.
NOTE: For Microcurrent programs, it is not necessary to set an intensity value (in mA) because
this is preset and automatically activated for all phases.

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 endorphin substances, reducing in this way the pain intensity. Therefore with TENS
we want to treat the severe and chronic pain due to the main musculoskeletal pains.
Moderada
de 10 mA a 20 mA
Intermedia
de 20 mA a 30 mA
The pain decrease following to the TENS currents application is due to these factors:
a. Gate control theory.
b. Endorphin secretion.
c. Different sedative effects in relation with the frequency.
GATE THEORY
If the electric signals that lead to the brain information about pain are stopped, also the pain per-
ception is eliminated. If, for instance, we hit our head into an object the first thing we do is massa-
ging the area affected by the trauma. In this way we stimulate the receptors related to touch and
pressure. TENS in continuous mode and in frequency modulation can be used to generate signals
similar to the ones 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 gained, the gate related to the sensory signals is
opened and the pain one is closed, impeding in this way the passage of these signals to the brain.
ENDORPHIN SECRETION
When a nervous signal proceeds from the pain area to the brain, it spreads through a chain of con-
nections joined together called synapse. The synapse can be seen as the space between the end
of a nerve and the start of another. When an electric signal reaches the end of a nerve, it produces
