Do Electronic Muscle Stimulators really work?

You might have seen ads for electronic muscle stimulators (EMS) claiming they will tone, firm, and strengthen abdominal muscles, help you lose weight, or get rock hard abs. But according to FDA, while these devices may temporarily strengthen, tone, or firm a muscle, no electronic muscle stimulator device alone will give you “six-pack” abs. 

Applying electrical current to muscles may cause muscles to contract. Stimulating muscles repeatedly with electricity may eventually result in muscles that are strengthened and toned to some extent but will not, based on currently available data, create a major change in your appearance without the addition of diet and regular exercise.

At this time, FDA is not aware of scientific information to support many of the promotional claims being made for numerous devices being widely promoted on television, infomercials, newspapers, and magazines.

Doctors may use electrical muscle stimulators for patients who require muscle re-education, relaxation of muscle spasms, increased range of motion, prevention of muscle atrophy, and for treating other medical conditions which usually result from a stroke, a serious injury, or major surgery. Again, the effect of using these devices is primarily to help a patient recover from impaired muscle function due to a medical condition, not to increase muscle size enough to affect appearance.

Warning: FDA has received reports of shocks, burns, bruising, skin irritation, and pain associated with the use of some of these devices. So it is very important that these devices be properly designed, manufactured, and labeled with clear and complete instructions for use and that anyone using them follows the instructions carefully.
