Electrical muscle stimulators, also referred to as EMS devices, are not only used in the medical industry for physical therapy and rehabilitation purposes, but they are being sold to consumers for the purposes of toning and strengthening muscles, specifically the abdominals. Currently, the U.S. Food and Drug Administration, or FDA, is responsible for regulating all sales of EMS devices in the United States. The administration has received reports of injuries due to use of the device and recommends that consumers only purchase products that have been approved by the FDA.
Electric Shock
According to the FDA, there have been reports of injuries related to electric shock when using personal EMS devices. Some of the muscle stimulators come with cables and leads that may or may not meet electrical safety standards. The danger for electrocution by the user or other household members exists when using illegally marketed devices that do not comply with federally regulated safety standards.
Skin Irritation, Bruising and Burning
Users of EMS devices have also reported problems with burns, bruises and irritation to the skin surface. The stimulation is delivered to the muscles by placing electrode pads on various parts of the body. Some users have reported skin irritation due to the electrode pads. Bruises and burns can occur when directions are not probably followed and the electrode is left in one place longer than recommended or the device doesn't meet safety standards. The FDA advises consumers to read and carefully follow instructions to avoid these types of injuries.
Interference with Implanted Devices
Another cause for concern is the use of EMS devices by people who have electical implants such as pacemakers or heart defibrillators. Interference with these types of implants have been reported and in some cases, hospitalization has been required. Consult your physcian before using a muscle stimulator if you have any implanted life-saving devices.
Warnings and Contraindications
In a lawsuit filed by the Napa County District Attorney's office against one of the manufacturers of a non-FDA approved EMS device, contraindications for use were cited. According to the legal ruling, EMS devices are not recommended for persons with cancer, phlebitis, epileptic seizures, inflammation of tissue, previous allergic reactions to topical gels, high blood pressure or heart issues. Pregnant women should consult their physician before using such a device.
