Biofeedback makes unconsciously run body processes
observable and experiential.
If, for example, muscle tension or skin moisture have
been measured, then the EOG.Biofeedback
"processes" eye responses.
The EOG Biofeedback procedure, which registers and
analyzes the movement of the muscles in the
eye area and uses the most modern computer technology for relaxation,
is new. Scientific research has shown that these muscle activities in
the eye area during mental processes are
responsible for depth relaxation: if we succeed in
relaxing these, the mind will also relax.
The EOG.micro biofeedback system directly affects the
vegetative nervous system. In this way the
stress symptoms are counteracted and their undesired consequences are avoided.
The EOG.micro has been successfully used for:
- Pain syndromes
- innitus, sleep disorders
- High blood pressure
- Mental training, e.g. in
the area of sports
- Learning disabilities,
Operation can be compared to
sleeping glasses: built-in sensors register muscle activity in the eye
area even if the eyes are closed and control corresponding sounds in
stereo CD quality. By using this acoustical feedback (EOG), the process
of inner perception is accompanied by the body's own rhythm – the
result is depth relaxation, which can activate the healing energy from
the resulting rest.
about active and passive Biofeedback
med. Akos Tatar
biofeedback, body functions, which usually occur unconsciously, such as
muscle tension, heart rate, eye movements and circulation, are measured
and fed back with suitable instruments. By using the audio-visual
feedback, the physiological functions of perception are made accessible
and brought under conscious control.
the course of treatment it has become easier to use the skills acquired
through biofeedback without using the device. It is thus learning about
body perception, self-control and self-healing.
first approaches were made in the 30's of this century, however, only
the technological developments in the past few years have made further
development possible. The following parameters can be derived using
several modules: skin conductivity, EOG (eye movement), EMG
(electromyography), EEG, skin temperature, pulse rate, amplitude of the
pulse, as well as respiratory excursion over thorax and abdomen.
is biofeedback applied?
is a scientifically recognized method at the intersection of medical
sciences and psychology. Biofeedback has been applied therapeutically in
almost all disciplines of medicine, even up to dermatology. The main
domain are neurovascular, neuromuscular and neurological-psychiatrical
illnesses, such as:
vascular cephalgia, orthostatic dysregulation, migraines, tinnitus,
post-traumatic headaches, post treatment of apoplexia and spinal trauma,
fibromyalgia, tenseness, sciatic neuralgia, chronic pain of all kinds,
incontinence, anorectal dysfunctions, obstipation, but also ataxia
treatment for Morbus Parkinson, depression, and much more.
Biofeedback in therapy
biofeedback has a favorable position in the biofeedback systems since it
can be applied actively as well as passively (see below).
biofeedback has been successfully applied for illnesses, which are
accompanied by increasing muscular tone (tension headache, torticollis)
or by increased agitation level (high blood pressure, anxiety disorders,
psychosomatic symptoms), but also in the area of neurology (tinnitus)
advantage of the therapy lies in the active participation of the patient
undergoing therapy, i.e. the patient must actively deal with himself and
Biofeedback in prevention, sport and meditation
to therapy, this method is also applied in the sense of prevention in
order to achieve good stress management using various relaxation
biofeedback serves to reduce arising stress in serious sports and to
fully utilize the resources during competition by using mental training.
biofeedback presents the possibility to perceive unconscious thoughts
during meditation. This is possible, since even fleeting thoughts are
accompanied by eye movement and reach the consciousness over the
We distinguish between three types of biofeedback:
a) Passive biofeedback, such as the respiratory biofeedback
according to Prof. Leuner.
b) Active biofeedback, such as EMG, EEG, pulse, temperature
c) Active and passive biofeedback, such as EOG biofeedback according
The passive biofeedback exerts its effect through the
afferent pathways of the optic nerve and/or acoustic nerve, which
continues to influence the reticular formation through the
tectoreticular pathways, which includes respiration, heart rate and
vessels in the basal part of the regulatory centers.
Passive biofeedback also works on animals. Gruber and
Taub worked with monkeys in order to control their muscular tension.[i]

meaning of eye movements
entire physiology of eye movement regulation for humans has not been
completely explained even today. The brain stem, cerebellum, thalamus,
striatum, parietal and frontal cortex participate in the complex

processes, such as calculation, visualization, etc., as the studies by

based on the connection between eye movements and post-traumatic anxiety
symptoms, attained importance during treatment of Vietnam veterans[vi]
and war victims.

patients decided to use the device.
minimum 4-week test phase was implemented with these 20 patients,
whereby the device was used twice daily for 20 minutes each.
and after concluding the test phase, the tinnitus was measured by
frequency and maskability, the hearing threshold was determined, and
the questionnaire was answered according to Göbel and Hiller.
the hearing threshold did not change.
The tinnitus values according to frequency and intensity of
the maskability were equally unchanged.
15 patients, the score according to Göbel and Hiller improved by 9
points (-5 to –13).
5 patients, the values remained approximately the same (+- 2

Control Of Mind
think or imagine or engage in any other form of mental activity,
your brain is active, but to no greater extent than when you engage
in any so-called physical activity, such as golf. Without a brain
you could not think, but neither could you play golf. At no time do
you feel your brain working; neither do you ever have tension
signals in the brain. As you learn to recognize tensions during
,mental activity, you will find them chiefly in the eyes and speech
regions but ~ not in the brain.
learn to control your thinking and emotions to a useful ~ extent
because these mental activities occur only if and when you ~ tense
your eye and speech muscles. However, you may' use every other
muscle in your body in thinking and in emotion, depending on the
patterns which correspond to your endeavors. Electrical measurements
show, for instance, that people often use their arm muscles in
your eyes and think about any matter. If skilled, you can*notice (1)
visual. pictures, called images, but also (2) eye tensions to look
at what you see in imagination. In thinking, also, you are likely to
use your speech apparatus to form words, but these are not spoken
aloud. , Electrical measurerrients disclose that you use the same
inuscles as you use in saying the same words aloud.
in visual imaginations you look at the objects you think about,
turning your eyes in the same way as if you were looking at real
imagination is a shorthand, a telescopic reproduction in which you
use your muscles just as you do in reality when you see objects of
persons and speak aloud. However, in mental activity the tensions
are miniscule. As said above, you will find that all other muscles
may and do participate
in some of your tensions-image patterns.
you engage in any mental or physical effort, the brain and the
muscles act approximately simultaneously. That the brain has an idea
first which later is expressed in the muscles is an incorrect view
for which no evidence ever was presented, although many people held
it and still do.
emphasized that the eye muscles and the speech muscles are of great
importance to thought. However, to emphasize that mental activity is
carried out by the entire body, note that at any moment if the
muscles either of the arms or legs or trunk are really relaxed
approximately to zero tension, the mind is also thereby quieted.
Why? Because in thinking or emotion, tensions in the parts mentioned
also participate. They too are the actors in any and every play of
the mind. Without them participating the mind is vacant.
this will enable you to apprehend why "the mind relaxes"
when the limbs or trunk or any other larger section of the body
relaxes. However,, remember that for this, the tertsion signals must
be reduced to zero or nearly so. If , the reduction falls short, ,
leaving tension signals of a diminished but sufficient order, then,
as when the telegrapher's signals are are still faintly present, the
messages are still there and the mind keeps on working....
