EMS stands for Electrical Neuromuscular Stimulator. The IF-4 MultiWave EMS system is indicated for:• Relaxation of muscle spasm;• Increasing local blood circulation and muscle re-education;• Prevention or retardation of disuse atrophy;• Prevention of venous thrombosis of the calf muscles immediately after surgery;• Maintaining or increasing range of motion.IF stands for Interferential Stimulation. The IF-4 MultiWave IF system is indicated for:• Symptomatic relief of chronic intractable pain.
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.
