impulses leave part of the body (for example the hand) and run along the
nerve tracts (through small-diameter nerve fibers) until they reach the
central nervous system where the impulses are interpreted as pain.
Conventional TENS activates large-diameter nerve fibers, blocking the path
of small-diameter nerve fibers at the spine. It therefore acts mainly on 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 everyday
pain. The first benefits can be seen after an average of 10/12 treatments
carried out on a daily basis (there are no contraindications for up to double
this amount).
The program can be repeated at the end of the session for particularly
persistent pain.
Session duration: 30 minutes (no less than 30/40 minutes).
Electrodes' positioning: form a square above the painful area as shown in
Figure 2.
Intensity: adjusted to a level between the thresholds of perception and
pain: the maximum intensity level is the moment in which the muscles
surrounding the area treated begin to contract (over this limit stimulation
does not become more effective, just more irritating, so it is best to stop
before that point).
W02 • Endorphinic TENS 0,5 Hz Frequency (medical program)
Cable type: TYPE 1 (see Figure 1 - Cable type.)
This type of stimulation produces two effects in relation to the position of
the electrodes: 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 2 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: 20 minutes, daily frequency.
Electrodes' positioning: photo 08 of the Positions manual or like in Figure
2,do not position the electrodes close to inflamed areas.
Intensity: to be adjusted in order to have a good solicitation of the
simulated part (15÷30mA), the sensation must be similar to a massage.
