analgesic), electro acupuncture training TENS (or delayed analgesic), TENS at maximum
values with antidromic action and consequently an immediate local anaesthetic effect.
The rehabilitative action of TENS is represented by its power to reduce pain thereby restoring
physiological conditions; this allows the patient to regain normal motor function. Consider a
patient suffering from irritating periarthritis; they either resort to using analgesics or learn to live
with the pain that often makes even the simplest movements impossible. Immobility reduces
metabolic activity making it impossible to eliminate algogenic substances. So a vicious circle
begins. In addition to relieving pain, TENS causes induced muscle stimulation increasing
metabolic activity and blood flow and improving tissue oxygenation with an intake of nutritional
substances. So the positive effect can be amplified by combining TENS with muscle
stimulation of the area concerned.
Position of electrodes and intensity levels.
The electrodes should be positioned to form a square surrounding the painful area using
Channel 1 and Channel 2 as shown in illustration 1(red up/black down are not important for
therapeutic purposes, follow instructions on electrodes position manual). The intensity should
be adjusted to a level between the thresholds of perception and thresholds of pain: the
maximum intensity level is the moment in which the muscles on the area treated begin to
contract; over this limit, stimulation does not become more effective, just more irritating.
A01 TENS rapid
•
Program also called conventional tens, used for analgesic purposes, blocking pain at the
dorsal horn of the spinal cord, 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 spinal cord. 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 once a day (there are no contraindications for up to double this
amount).
The program has a duration of 30 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 over the painful area as shown in illustration 1.
A02 TENS endorphinic
•
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 over the painful area

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