In case of complains presence, disclosure during inquiry and examining of the patient or appearance during device treatment it is mandatory to treat skin zones that have appeared due to peripheral, segmentary, supersegmentary or combined nervous mechanisms. Zones of this kind include the following zones.
Zakharyin – Head’s zones
These are zones of skin painfulness distinguished by their singularity and persistency (from dumbness up to paresthesiae) and combined with local skin induration. Zone of skin painfulness (hyperalgesia) may be of different size and shape; often it does not coincide with sensory innervation territory.
Trigger zones. Exteroceptive, proprioceptive and interceptive trigger zones are distinguished.
Exteroceptive trigger zones may clinically manifest by:
- local skin induration, painful skin protrusions, gooseflesh on a limited part of body, spots of disturbed pigmentation or desquamation;
- local sweating and thermoregulation disturbances, reddening or paling of separate skin areas, other vasomotor disturbances;
- “sticking” effect of sliding fingers or device’ electrodes on a limited skin area, changes of electric skin conductivity (impedance), etc.
Proprioceptive muscular trigger zones clinically manifest by muscular tissue induration of various location, shape and size from several millimeters to several centimeters). Local painfulness may manifest as pain of various intensity which begins to disturb the patient after extension or pressure (for example, after motions or palpation). In certain cases the pain manifests spontaneously and its intensity may deprive the patient of working ability. Sometimes the pain is so intensive that leads to limitation or complete loss of function of some organ or part of body.
Trigger zones in connective tissue are accompanied by formation of local induration of fasciae, ligaments, periosteum. Formed fascial trigger is distinguished from a muscular one only by the fact that it possesses significant intensity (not disappearing after usual measures for muscles relaxation) and location often not corresponding to muscular bundles and places of their fixation.
Clinical disclosure of visceral trigger points is unfortunately methodically difficult. More often interceptive triggers find themselves as viscerodermal and visceromotor manifestations (that is, skin, muscular and fascial zones and Zakharyin-Head’s zones).
Presence of an exclusive capacity — “biological” feedback — in DENAS device gives a possibility of diagnostics (disclosure) and exact locating of latent (hidden) trigger zones (“neurodystrophy areas”, “fibrosis”, “microzone asymmetry areas”, etc., more than 25 names) as well as defining of their appearance or regression dynamics.
It is necessary to distinguish the following signs of latent trigger zones disclosed during device treatment (further-asymmetry zones).
- Sensitive asymmetry — local change of skin sensitivity. During treatment local change of skin sensitivity is found out (the patient
feels an increase or decrease of pricking in this area in comparison to other areas).
- Time asymmetry. There are two methods of time asymmetry express estimation. First method: the operator counts packs of pulses (signals) generated by the device within the period of its work in dozed mode during single placing on a definite skin zone. Then, in the same way, number of pulses is registered on another skin zone, which, in the majority of cases, is symmetrical to the first one. Difference of pulse numbers on symmetrical skin areas witnesses time asymmetry presence.
In the second method (which is more convenient during self -treatment) during device treatment in “MED” (or “Test”)mode a time interval between the moment of device’ electrodes placement on a skin area and the moment of light and sound signal is registered (t sec). Then, in the same way, the time of light and sound signal is registered in another skin area, which is, in the majority of cases, symmetric to the first one (t2, sec). After that t, and t2 are compared and difference is obtained. The whole row of differences disclosed during testing of a certain part of body is analyzed. Difference of time intervals more than 3 seconds is considered to be an index of time asymmetry.
- Absence of light and sound signal during treatment in “MED” (or “Test”) mode.
- Spontaneous switch-off of the device during its operation.
- Local change of skin color. After treatment of a skin area in “MED” (or “Test”) mode reddening or paling appears at the place of device electrodes position (contact asymmetry) or in another body area (distant asymmetry) that differs this area from the others.
- Local increase of sweating. After treatment of a skin area in dozed mode droplets of sweat appear at the place of device’ electrodes position that differ this area from the others (contact asymmetry).
- Change of the timber of device’ work sound on a separate skin area.
- Change of the timber of light and sound signal on a separate skin area.
- The operator has to apply some force for electrodes advance on some skin area during moving of the device working in “Therapy” 77Hz mode (“sticking” effect).
- It should be remembered that trigger phenomena on the skin may appear during or after the procedure anywhere, on any skin area, in some cases they are not associated with skin area treated by the device (distant asymmetry). It requires a dialogue with the patient concerning the dynamics of his sensations and attention of the operator
Trigger zones disclosed during questioning, examination of the patient and during device’ diagnostics are mandatory for treatment in “Therapy” 77Hz mode, energetic level is defined by pain syndrome degree and exposition of apparatus treatment is individual.
