An electrically-powered device assembly intended to apply various modes of electrical stimulation transcutaneously to treat/prevent neuromuscular symptoms and disorders typically as a form of physical therapy [neuromuscular electrical stimulation (NMES)/electronic muscle stimulation (EMS)]; it may in addition be intended for transcutaneous electrical nerve stimulation (TENS) to treat pain, and/or electroacupuncture. It includes an electric current pulse generator and noninvasive electrodes; it is not intended for tremor suppression. Clinical applications typically include relaxation/re-education of muscles, prevention of muscle atrophy, and improvement of blood circulation.
