In medicine, the term electrotherapy can apply to a variety of treatments, including the use of electrical devices such as deep brain stimulators for neurological disease. The term has also been applied specifically to the use of electric current to speed wound healing. The first medical treatments with electricity in London have been recorded as far back as 1767 at Middlesex Hospital in London using a special apparatus. The same was purchased for St. Bartholomew's Hospital only ten years later. The record of uses other than being therapeutic is not clear, however Guy's Hospital has a published list of cases from the earlier 1800s.
