How Microcurrent-based Biofeedback Devices,  (i.e... SCENAR® **  & DENAS® **) Systems Function

The microcurrent device works through your skin (transdermal). It uses computer-modulated, electrical impulses to stimulate your brain (electro-neuro stimulator). The brain responds with its own signal which is picked up by the microcurrent device.

The device then interprets
the brain's response and modifies its next impulse back to the brain to work at restoring balance to the body (This is called "active reflex biofeedback"). The brain, in turn, sends a modified response (and so on) until equilibrium is achieved (homeostasis).

During this 'conversation', of constantly varying
electrical frequencies and waveforms, the brain also instructs the nervous system to generate Neuropeptides (the key biochemicals needed by your body to heal itself - the body's own pharmacy). This is what the body was designed to do.

After an injury or onset of disease
the communication system between the brain and the affected body part can 'break down' or 'get used to' the signal from that body part. The brain begins to accept the abnormal signal as "Normal". This is a reason why many conditions become chronic and unresponsive to treatment. Through the miracle of science, the microcurrent device then breaks the body out of this habit and restores correct communication resulting in effective and more complete healing.

The electrical pulses from the microcurrent device
have been specifically designed to contain numerous random features to prevent your body from 'adapting' to the stimulation and to help the body continue the healing process to its completion.

Because of its unique, computer controlled biofeedback capabilities
and ability to stimulate Neuropeptide generation, the microcurrent device achieves excellent healing results.

DENAS and SCENAR is very different from other electrotherapy instruments
such as TENS or Electro acupuncture. Tens units are mainly used to provide pain relief. Electro acupuncture instruments have a broader range of application, but they lack any bio-feedback capability. Only the DENAS and SCENAR instruments combine energy measuring functions along with real-time feedback and constant adjustment to deliver just the correct type and amount of energy to the body.

DENAS PCM models, and some expensive SCENAR models, produce both local effects by stimulating the skin, blood and muscle vessels by influencing nervous, endocrine and immune systems.
Overall, these instruments are an effective, non-invasive medical technology, which works by stimulating the body's inherent self-healing mechanisms, with no undesirable side effects.

DENAS ® and SCENAR ®  are now internationally recognized as an expression that literally understood to mean "a tool that's used to help heal oneself and bring good health".  The tools commonly used for (DENS Therapy) are the PCM models of DENAS devices produced by the DENAS MS Corporation in Yekaterinburg Russia.

Early microcurrent instruments were originally developed
for the Russian space program to overcome the unique problems of space travel. Pharmaceuticals were impractical due to the specificity of each drug, leading to a need to store a large variety and quantity of drugs, and also due to the introduction of toxins into the water recycling system, such that one toxin exposure may affect the whole crew.

A Russian team of doctors and scientists, based at Sochi University and led by Alexander Karasev in the late 1970s, developed a method of treatment that was energy efficient, multi-applicable, portable and also non-invasive. They were the first people to achieve repeatable therapeutic treatment using electrical signals to stimulate the immune system. Head scientist Professor Revenko claimed that there were very few illnesses SCENAR® devices could not treat and often cure. Tests conducted in Russia have since shown that SCENAR® based treatment proves effective in 80% of cases.

Microcurrent devices were immediately dubbed as 'Star Trek' devices
by the press because of its origins and its similarity to the 'all-curing' medical scanner used in the popular television series, called "Star Trek".

IT SHOULD BE NOTED that In Russia today, DENS therapy is a part of the mainstream medicine
and it is registered by the Russian Ministry of Health as an official independent method of treatment. It is taught in medical colleges as a separate discipline and may be pursued by students as a major professional specialization.

Effects Expected from DENS Treatment

l   Pain-killing effect (lasts for 4 to 48 hours)
l   Effect of parabolise in the nerve endings of the peripheral nervous fibers blocks the transmission of pain impulse.
l   Dominant focus in the cortex of the brain, suppresses the pain focus.
l   Current considerably reduces oedema around the nerve fibers.
l   Inflammatory effect - With inflammation there is an inflammatory focus, which is Anti-Oedema - Reduces swelling.
l   Anti-shock, Anti-allergic affect - can be observed with food allergy, rash, bites, rhinitis and broncho-spasm.
l   Hyper perfusion - (blood vessel dilation) effect
l   Fever Reduction (Ant pyrogenic) Effect - Obtained by treatment of the main blood vessels.
l   Normalization of Metabolic Processes
l   Increased solute levels in blood.  Stimulated active consumption of oxygen and nutrients increases venous flow and removal of metabolic by-products.  Increase in lymphatic flow.
l   Normalization of cell, tissue and system function
l   Normalization of the immune system.  Due to SCENAR input, neuropeptides are produced, which cascade down to create new bio-active compounds.  These will correct and balance the relation between biochemical and functional systems in secondary tissues and cells.
l   Normalization of the hormone balance.  In connection with the production of neuropeptides.
l   Faster regeneration of tissue - increased healing of wounds
l   General Effects - from increase of levels of energy and immunity
l   Better sleep - better appetite - better mood

In Russia, there are hundreds of thousands of cases of SCENAR® type devices in use, along with several thousand practitioners who currently utilize the device as their principal treatment instrument. A vast wealth of information is available from research papers, clinical reports and training manuals. The device is used on most types of disease or injury: circulatory, sensory, respiratory, neurological, genitor-urinary, muscular-skeletal, gastro-intestinal, endocrine, immune and psychological disorders.

How SCENAR® Based Systems Function

DENAS & DiaDENS (DENS devices which use a very advanced technology) gives pain relief in three ways:

1) By providing a new signal
, dominant focus is formed in the cortex, which causes de-localization of the previously dominant focus of pain and activates the parasympathetic nervous system.

2) By changing the sensitivity
and decreasing the lability in the thick A and thinner C nerve fibers. The faster A fibers depolarize the substantia gelatinase (glial cells) and pain impulses arriving via the C fibers are prevented from continuing (Gate theory).

3) By activating cortical and sub-cortical centers
to send descending efferent impulses that increase blood flow and stimulate local humoral mechanisms, viz., the production and release of endorphins and increasing the activity of enzymes, such as acetyl cholinesterase, histaminase and kinases.

DENS devices, like all advanced microcurrent based instruments,
use biofeedback.  By means of sending natural signals through the nervous and vascular systems; it is able to teach the body to heal itself. The device sends out a series of signals through the skin and measures the response. Each signal is only sent out when a change, in response to the previous signal, is recorded in the electrical properties of the skin. Visible responses include reddening of the skin, numbness, stickiness (the device will have the feeling of being magnetically dragged).  As it is moved there is an increase in the electronic clattering of the device.

There are three types of Nerve fibers.
  They are classified according to nerve diameter, speed of conduction, neurotransmitter and function.  C-Fibers are the slowest being as they are non-myelinated.  These account for 70% - 80% of nerves within the body.

Because of the primary purpose of basic electrical-stimulation devices, only the A and B fibers are targeted leaving the C-Fibers untouched.  Another secret of any advanced SCENAR® **, device is that it targets mostly C fibers and it is these fibers that are mostly involved in DENS Therapy.  C fibers are sensory fibers that the brain gets its information through, which allows it to filter different stimuli and thus maintain dynamic equilibrium.  The failure of the brain to maintain dynamic equilibrium within its own body is the ultimate cause of disease.

The C-fibers, which comprise 85% of all nerves in the body
, react most readily to the electro-stimulation and are responsible for the production of neuropeptides and other regulatory peptides.

The body can get accustomed
to a stable pathological state, which may have been caused by injury, disease or toxicity.  The DENS device catalysis the process to produce regulatory peptides by stimulation of C-fibers for the body to use where necessary. It is these neuropeptides that in turn reestablish the body's natural physiological state and are responsible for the healing process. As these peptides last up to several hours, the healing process will continue long after the treatment is over. The large quantity of neuropeptides and C-fibers in the Central Nervous System can also result in the treatment on one area aiding with other chemical imbalances, correcting sleeplessness, appetite and behavioral problems.


There are various types of neurotransmitters, which are usually specific to a certain type of nerve or function.  Neuropeptides were the last to be discovered.  They withdraw down a cascade creating other neuropeptides and other bioactive compounds that are specific to different systems.  Thus a bioactive compound low down in the cascade of degeneration can be biologically active elsewhere in the body from where the originating neuropeptide was released.  It is therefore possible that the degenerating cascade can influence all systems albeit at sequential points in time.  Neuropeptides also influence cellular activity at the DNA level by altering gene structure to either increase or decrease gene expression.

Neuropeptides are also involved in memory regulation
.  DENS-Therapy will therefore address not only the systemic influences of pathology but also the psycho-emotional aspects.

The advanced DENS version of
SCENAR® **, treatments alters nerve physiology such that Refractory Times where a nerve cannot normally conduct another impulse are shortened.  In this way, DENS treatment is 100% safe.  Any DENAS or DiaDENS device cannot input an electrical impulse into the body without the body being able to respond.  By altering the input signal in every way possible such that no 2 consecutive signals are identical, the body cannot accommodate to the signal and is forced to respond.

Input signals to the body
are very similar in form to natural nerve impulses.  The DENS device modifies the pathological signal to the brain so that the brain becomes aware and thereby triggers an increased response to the pathology.  Healing times are markedly reduced and more dramatic as a result of the massive response to DENAS or DiaDENS treatment signals.

Pain relief using any DENAS or DiaDENS based device
has been found to be more profound than using narcotics due to the neuropeptide cascade effect.  This was tested on cancer patients and people with bone fractures.

DENAS & DiaDENS devices, in general, have also been credited with vastly reducing recovery times.
Russian athletes have been known not only to compete after serious injuries, but even to break world-records. In accident and emergency wards, its ability to aid recovery is used to help victims of cardiac arrest, massive trauma and coma. It has recently been discovered to also aid in improving learning ability, memory, sexual function and improved physical health. Without a doubt, many trials in Russia have realized the extraordinary effectiveness that an advanced SCENAR's usage provides for pain relief.  Both cancer and fracture patients have found more pain relief from the release of natural opioids after a DENS-Therapeutic treatment than from administered opiates.

DENAS & DiaDENS Devices Assist in Pain Management

The DENAS & DiaDENS devices have been used to assist in pain management and relief in all types of disorders- circulatory, respiratory, neurological, genitourinary, endocrine, musculoskeletal, immune, gastrointestinal and even psychological discomfort. A DENAS or DiaDENS device is particularly effective for various types of organic and referred pain, musculoskeletal pain, and, as evidenced by its use for the Russian Olympians, for acute conditions such as fractures and sprains.

Effectiveness of DENS Based Therapy

It is important to note that a DENS device does not treat a particular disease or condition. However, results reported for all types of SCENAR® devices have been remarkable. There seems to be very few ailment categories that it cannot assist. Improvements in particular conditions are simply the result of applying procedures developed over two decades of the device's use to affect a change in skin/body response to a DENAS or DiaDENS signal/impulse.

In the UK, the devices are licensed by the British Standards Institute
for pain relief only. In The US, these systems are approved under a 510k exemption as a tens machine with bio-feedback. However, because of the nature of the device, stimulating the nervous system, the Russian experience is that type of microcurrent systems do affect all human body systems.

The Russian experience suggest
that it can be effective for a very broad range of diseases, including diseases of the digestive, cardio-vascular, respiratory, muscular-skeletal, urinary, reproductive and nervous systems.

It is also useful for managing ENT diseases, eye diseases, skin conditions and dental problems
. It has also been found beneficial in burns, fractures, insect bites, allergic reactions, diseases of the blood and disorders involving immune mechanisms; endocrine, nutritional and metabolic disorders; stress and mental depression, etc.

How Often Is Treatment Needed?

In order to create a continuous flow of circulating regulative peptides DENS Therapeutic action must be given quite often. For any fresh injury or any acute inflammatory process treatment needs to be intensive, ideally once or even twice daily. For chronic conditions, treatments are ideally given three or four times a week initially. As things improve the frequency can be reduced.

A course of treatments will vary
from individual to individual, and takes into account such factors as the stage of the pathological process, the person's age, state of health, and so on.

Is It Safe?

As the DENS device impulse is similar to endogenous nerve impulses, it is non-damaging and safe. Only people with cardiac pacemakers are not allowed to have any type of DENS-Therapeutic treatment.

Children and pregnant women can be treated,
and even animals enjoy it!


In over twenty years of use in Russia and Europe, no unwanted side effects have been noted. Since the impulses sent by the device are similar to the body's own impulses, these are quite safe, even for children and pregnant women. The peculiarities of DENS-Therapy means that there are few contra-indications.

The obvious contraindications
are cardiac pacemakers and other such electrical implants, individual intolerances, alcohol intoxication and obscure infectious diseases.

With all this in mind, wherever other electrotherapies have effects, DENS-Therapy will also be useful,
and indeed, it has been found to be very useful when other electrotherapies have failed. As with all therapies/methods that stimulate rather than suppress the body's own healing power, the initial effect may be a "healing crises" that makes the person feel worse before feeling better. A lack of energy and general malaise may result as old problems and toxicities are brought to the surface for treatment and elimination. This necessary bit of housekeeping soon passes and is followed by new heights of wellbeing, increased energy and a more refreshing sleep.

for Biofeedback Instruments & Advanced
DENAS & DiaDENS  (SCENAR® type) Systems
Brief Webinar Outline

Basic Requirements to Attend

1. You should have at least a general interest regarding the Biofeedback Equipment that we will be discussing.  You don't need to own one of the DENAS instruments that we love to talk about.  However, for training purposes, it will be good if you have any early version or the newest model of the DENAS MS Corporation's "PCM" instruments.  Of course our Webinar will be discussing matters such as: "How to use the PCM", "What instrument settings should be" or "How can you use your device to take advantage of some of your device's best features for your particular needs... etc."

2.  For the Webinar, you will need an operational Laptop or Desktop PC
(Windows Operating System) or MAC (with a MAC OS system).  Your computer will need to have a standard keyboard and display with functioning speakers so you can see, hear and type questions you may have for the instructors).  Optionally, you may have a microphone and Web Camera (because you may wish to speak or visually demonstrate something to all of the students and instructors in the virtual classroom).  We consider a webcam a "Nice-to-Have" but non-essential piece of equipment.  Some of our best past presentations were unplanned discussions with people who attend and have interesting solutions to issues that we were discussing.  Based on our past experience, most people who attend simply type in (or "copy and paste) their comments or questions during a Webinar performance. 

3.  You may have your own application software to copy
the live program (to watch later)   Initially, we do not plan to copy our Webinar for future use.  However, if things are going well later on, we will copy these sessions and have them available on "" intended for individuals who could not attend the live performance for various reasons.  For example, someone may wish to view a Webinar performance may live in a time-zone that is not convenient to their work schedule... etc.

4.  Our intention is to provide the DENAS webinar training
as a service for our customers in a convenient and comfortable way without ever charging a fee.  If we find that there are technical limitations, it may be necessary to set a "first come, first serviced" policy to limit class sizes.  This website, "" will be our focal point to relate policy issues and/or schedule changes and especially for information dissemination.  We will be sending you "reminder emails" a few days prior to each webinar.  To help everyone's personal scheduling, at this time we are planning for our Webinar to start at 7:00 PM PT (California time) on the
third Saturday of each month.

5. You may wish to contemplate some of the subject matters identified below.   Additionally, we want to include matters important to your ideas and questions.  A few of our thoughts are outlined as follows:
