TENS 01 • Fast TENS
Program also called conventional tens, used for analgesic purposes; its purpose is to induce
the organism into blocking pain at the spine, in accordance with the "Gate Control Theory" by
Melzack and Wall. Pain impulses leave part of the body (for example the hand) and run along
the nerve tracts (through small-diameter nerve fibres) until they reach the central nervous
system where the impulses are interpreted as pain. Conventional tens activates large-diameter
nerve fibres, blocking the path of small-diameter nerve fibres at the spine. So action is mainly
taken against the symptom: to simplify it further, the wire transmitting pain information is
obstructed.
Treatment duration should be no less than 30/40 minutes. Conventional tens is a current
that can be used to treat general everyday pain. The average number required to benefit
from the treatment is 10/12 per day (there are no contraindications for up to double this
amount).
The program has a duration of 40 minutes in a single phase. The program can be repeated at
the end of the session for particularly persistent pain. The nature of the impulse means that the
patient may experience an "addictive" effect due to which the impulse will be felt less and less:
if necessary the intensity can be increased by one level to counter this effect.
Position of electrodes: form a square above the painful area as shown in illustration 1.
TENS 02 • Endorphinic TENS
This type of stimulation produces two types of effects according to how the electrodes are
positioned: positioning the electrodes in the dorsal region, see photo 08 in the positions
manual, promotes the endogenous production of morphine-like substances capable of raising
the pain perception threshold; positioning the electrodes to form a square above the painful
area as shown in illustration 1 produces a vascularizing effect. Vascularization increases
arterial flow and consequently aids the removal of algogenic substances and helps to restore
normal physiological conditions.
Treatment duration 30 minutes in a single phase, daily frequency.
Do not position the electrodes close to inflamed areas.
Intensity adjusted for good solicitation of the part stimulated, the sensation must be similar to
that of a massage.
TENS 03• TENS at maximum values
Very short duration, 3 minutes. Blocks pain impulses peripherally creating a proper
anaesthetising effect in the area treated. This type of stimulation is suitable for injuries or
bruises when rapid action is required. The intensity selected is the maximum tolerable value
(well in excess of conventional tens, and therefore with considerable contraction of the muscles
surrounding the area treated). That is the reason why such stimulation is undoubtedly the least
tolerated but is extremely effective. This type of stimulation is not recommended for particularly
sensitive people and in any case the electrodes should not be positioned in sensitive areas
such as the face and genitals or close to wounds.
Position of electrodes: form a square above the painful area as shown in illustration 1.

WARNING
Create a square area with the
electrodes, over the painful zone.
Keep 4cm minimum
between electrodes.
