Abstract
Abstract A circuit for electrotherapy and electronic acupuncture, in which a pulse train is produced having negative pulses of a repetition rate of between 100 and 500 Hz, arranged in groups having a repetition rate of between 1 and 50 Hz. A positive bias is provided so that the integral of the pulse train signal is zero. The signal is randomly switched sequentially from one skin stimulus site to another with application times which can be adjusted between about 1 and 20 seconds (or more), to reduce or prevent brain habituation. Optionally there is a rest period between applications of the signal, in which no signal is applied to the skin sites.
