An electric muscle stimulator is a device that sends small pulses of electric energy through a muscle to cause contractions. These contractions may cause the muscle to strengthen, increase the muscle's mobility or promote blood flow. Electric stimulators are available over-the-counter and through prescription. The Federal Drug Administration regulates electric muscle stimulators in the U.S. and only certifies certain usage of the device.
Blood Circulation
Electric muscle stimulators can improve blood circulation, which is beneficial for recent muscle damage or diabetics who are at risk for poor blood circulation.
Spasm Treatment
Muscle spasms can be treated with an electric muscle stimulator under professional supervision. The device reduces spasms by relaxing the muscle.
Atrophy Prevention
Medical professionals use electric muscle stimulators to prevent muscle atrophy and amputation on patients with unused limbs. The device stimulates the muscle to prevent decay from disuse.
Toning
Over-the-counter electric muscle stimulators can be used to achieve temporary muscle definition. The device tones and firms muscles through repetitive contractions.
Weight Loss
Electric muscle stimulators have been marketed as a quick solution to spot reducing or losing weight. The FDA has not approved these devices as a weight loss tool.
