The use of electricity in medicine has long been controversial, notes health physicist Timothy Jorgensen. Eighteenth-century polymath Benjamin Franklin applied shocks to paralysed muscles with temporary success. In the 1930s, neurologist Ugo Cerletti pioneered painful but effective electroconvulsive therapy for schizophrenia and depression. Yet even today, “no one is sure exactly how ECT works”, says Jorgensen in his brilliant book.
