IDEA
In the early 1970-s, new methods of treatment started filtering through to the Soviet Union. These mainly were methods of ancient oriental medicine — reflexotherapy (needle reflexotherapy, acupuncture), which was then known as zhen-jui method.
Reflexotherapy (as you can see from the term) is a part of the treatment concept based on the principle of reflex — the most universal mechanism of nervous activity.
One of the main reasons why this method of treatment became so poplar was that it allowed treating diseases without medications or significantly reducing the use of medications.
Another important thing here is that with professional treatment there are no side-effects, while most medications cause them.
Such approach is only successful when applied by professional acupuncturists, but even in this case it does not guarantee 100% result. Self-treatment is, of course, out of the question.
Using reflex mechanisms for self-treatment is a very good idea. And it can be used for treatment of nearly all diseases. As any irritation is transmitted in our body in the form of nerve (electrical) impulses, it should be possible to make a universal “electrical” pill, why not? That is what Alexander Karasev was thinking about in 1972.

Magneto
The first device consisted of an engine (taken out of a children’s toy) with contact breaker. The engine broke the contacts, which were connected to the transformer with battery (like magneto in a tractor). The transformer was connected to the electrodes. Impulses, which were generated by contact break (self-induction) were close to the nerve impulses. When the electrodes were placed on the skin in the area of pain sensations you could achieve pain-relief effect. This device was the ancestor of all TENS devices (devices for pain-relief).ith time, the toy engine was replaced with generator, the contacts were replaced with electronic switch, and the transformer was left as it was. This is how a TENS was born. And all TENS devices are still made on the same principle.

1990

Research Laboratory “LET Medical”

A. A. Karasev founded Research Laboratory of Medical Electronics “LET Medical”.
SCENAR 035

This is a modification of the 032 , which was made specially for serial production at “ARKAIM” enterprise (Essentuki). Solar batteries were removed, power supply became exchangeable – one galvanic cell, size AA. Absolutely all devices of this series were tuned by Alexander Karasev personally… as well as all other devices produced up to now.

 

1993

Registration Certificate

“SCENAR” series devices are approved for practical application by the Health Ministry of the Russian Federation. Registration Certificate 29-199/40-5 of August 23, 1993.

   
SCENAR DS532М

First device for personal use. Casing was the same as in the remote electrode of the 513. This device was built completely with digital components, which were mounted very densely on the circuit board. Only energy level and frequency could be regulated. Power supply: built-in accumulator, built-in charger, charging from power adapter.

2002

COSMODIC technology

Technology of medication-free regeneration and recovery.
   
SCENAR VX735Ag

Professional device which is implementing combined technology of treatment SCENAR-COSMODIC. Continued modification of the 735 series. This device had electrodes made of pure silver, in the form of “sleigh runners”, which later would become detachable. All output characteristics were changed and COSMODIC technology was improved. All the rest remained as in the previous 735.

SCENAR PS705

Analog of the 713 but in the “Pocket” series casing, OKW. Electrodes are unusual — in the form of three bent plates, looking like sleigh runners. Again made of Zepter stainless steel. The front-end part of the electrodes allowed working on small areas and the part of the electrodes placed on the underside of the casing allowed to lie on them during prolonged treatment. Flat casing was used specially for that. Power supply: 2 galvanic cells or rechargeable batteries, size AA.
