TENS1 • Fast TENS (medical program)
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. Therefore, this action
is mainly taken against the symptom: to simplify it further, the wire transmitting
pain information is obstructed.
Conventional TENS is a current that can be used to treat general daily pain. The
average number required to benefit from the treatment is 10/12 per day (no
contraindications in doubling this amount).
The program can be repeated at the end of the session for particularly persistent
pain. Due to the nature of the impulse the patient may experience an addictive
effect, meaning that the impulse will be felt less and less: if necessary, the intensity
can be increased by one level to counter this effect.
Session duration: 40 minutes (no less than 30/40 minutes), in a single phase.
Electrodes' positioning: form a square above the painful area as shown in Figure1.
Intensity: to be adjusted in order to have a good solicitation of the stimulated part,
but not over the pain threshold.
TENS2 • Endorphinic TENS (medical program)
This kind 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
Figure 1 produces a vascularizing effect. Vascularization increases arterial flow and
consequently aids the removal of allogenic substances and helps to restore normal
physiological conditions.
Session duration: 30 minutes in a single phase, daily frequency.
Electrodes' positioning: photo 08 of the Positions manual; do not position the
electrodes close to inflamed areas.
Intensity: to be adjusted in order to have a good solicitation of the stimulated part,
the sensation must be similar to a massage.
