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, frequency 2Hz, impulse width 250μs.
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.
P02 • Sequential TENS
(Medical program)
The program alternates continuous cycles with different frequency and impulse width
for 30 minutes. The program alternates 3 seconds at 100 Hz – 150 μs (tens
conventional) and 3 seconds at 2 Hz – 200 μs (tens endorphinic) to reduce pain and
increase the blood and oxygen flow on treatment area. This program is suggested for
generic pain not related to inflammatory situation. These impulses aid muscular
trophism on treatment area (useful in Periarthritis, for example).
Position of electrodes: form a square above the painful area as shown in illustration
1.
Intensity adjusted for good solicitation of the part stimulated, the sensation must be
similar to that of a massage.
P03 • Conventinal TENS
(Medical program)
Program also called fast 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 30 minutes in a single phase, 110 Hz and 180μs. 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

P04 • Modulated TENS
– frequency modulation
(Medical program)
The waveform frequency continuously varies from 10Hz to 100 Hz, with impulse width
of 250μs: the sensation is quite different from the one of constant frequency (P03). The
peculiarity of this impulse is that it can stimulate muscular fibers of different diameters.
It has great antalgic purposes. The patient can choose P03 or P04 as preferred. The
limit of this program is that it cannot be used during inflammatory conditions.
