Andy Coghlan reports on the application of electric currents to the body to speed up healing as research in its infancy (29 July, p 15). The Soviet Union developed as part of its space programme an instrument resembling a TV remote control, called Skanna, to treat astronauts in a non-polluting way in space. My local health practitioner has been using this system for a few years after training in Bulgaria. He successfully treated me after I tore a tendon and sprained my ankle.
