Vega machines are a type of electroacupuncture device used in Vega testing, which proponents claim can diagnose allergies and other illnesses. The forerunner to the Vega test was electroacupuncture according to Voll developed by Reinholdt Voll in the 1950s. Helmut Schimmel modified the technique in the 1970s and presented it under the name Vega test.[1]
