Through history there have been many methods of addressing the meridian system. Acupuncture using needles, heat or pressure was a method developed over 3,000 years ago in Traditional Chinese Medicine (TCM). It uses the body's energy anatomy, the meridian system, to address physical symptoms. Meridians, pathways of energy, are accessed via points along the body.
Today various combinations of these points are addressed using heat, light, cold laser, sound, tapping, massage and mild electric current. Electro-acupressure technology has been available for close to 100 years and extensively explored by German physician Reinhold Voll in the 1950s. Voll used his EAV machine to test the relative speed of a meridian (and physical strength or weakness) when exposed to the frequency of a substance. He then helped re-establish a healthy movement of energy in relation to this substance by stimulating the end points of the meridians.
Other German physicians such as pediatrician Peter Schumacher further explored electro-acupressure in the 1980s and 90s. By first muscle testing using glass vials containing the frequencies of various substances, he unearthed dissonance connected to the client's symptoms. By re-introducing these dissonant frequencies through meridian points, he found that he could promote resonance to them. The meridian points he uses are those of Chiropractor Dr. Jim Scott adjusted in 1991 by Schumacher's colleague Jurgen Hennecke. Schumacher published a book on his work in 1998.
The BER protocol and technology continue in the traditions of Voll and Schumacher.
