The SCENAR device is an advanced form of electrotherapy for medical care of acute and chronic pain by using two physiological principles: that the body provides its own healing capabilities and continually employs the process of self-regulation to maintain health.

It works by sending high amplitude electrical impulses through the skin, which stimulates C fibers (a type of nerve fiber) that conduct nerve impulses and transmit information to the brain about the location of tissue damage and pain.

The electrical pulses can have a profound effect on organs via the nerves of the body, which can help normalized metabolism, improve blood circulation, decrease edema, exert analgesic and antiphlogistic impacts, and other beneficial uses.
