A system of diagnosis and treatment based on the measurement of the electrical characteristics of acupoints (specific sites for needle insertions), the results being used to determine a specific remedy based on the diagnosed research.

The term was named for Dr. Reinhold Voll, who in 1939, started to apply electroacupuncture in his medical practice and in 1953, together with engineer F. Verner, started to develop his special method of electroacupuncture.

Electroacupuncture, also known as "electroacupuncture according to Voll" (EAV), "electrodermal screening" (EDS), "bioelectric functions diagnosis" (BFD), "bio resonance therapy" (BRT), or "bio-energy regulatory technique" (BER), is a controversial alternative medicine method of using electrodiagnostic devices to diagnose and to treat "energy imbalance" often using homeopathic products, first used by Reinhold Voll by combining "acupuncture" with "galvanometer" (detects, measures, and determines the direction of a small electric current) in 1958.
