The same study also indicates that EMS may lead to increased muscle mass. EMS may lead to statistically significant improvement in quadriceps muscle strength, however, further research is needed as this evidence is graded as low certainty. In the case of TENS, the current is usually sub-threshold, meaning that a muscle contraction is not observed.įor people who have progressive diseases such as cancer or chronic obstructive pulmonary disease, EMS is used to improve muscle weakness for those unable or unwilling to undertake whole-body exercise. This is distinct from transcutaneous electrical nerve stimulation (TENS), in which an electric current is used for pain therapy. In medicine, EMS is used for rehabilitation purposes, for instance in physical therapy in the prevention muscle atrophy due to inactivity or neuromuscular imbalance, which can occur for example after musculoskeletal injuries (damage to bones, joints, muscles, ligaments and tendons). Īthlete recovering with four-channel, electrical muscle stimulation machine attached through self-adhesive pads to her hamstringsĮlectrical muscle stimulation can be used as a training, therapeutic, or cosmetic tool.
Ī number of reviews have looked at the devices. In the United States, EMS devices are regulated by the U.S. The use of EMS has been cited by sports scientists as a complementary technique for sports training, and published research is available on the results obtained. The impulses mimic the action potential that comes from the central nervous system, causing the muscles to contract. The electrodes are generally pads that adhere to the skin.
ELECTRIC MUSCLE STIMULATOR SKIN
The impulses are generated by a device and are delivered through electrodes on the skin near to the muscles being stimulated.
EMS has received an increasing amount of attention in the last few years for many reasons: it can be utilized as a strength training tool for healthy subjects and athletes it could be used as a rehabilitation and preventive tool for people who are partially or totally immobilized it could be utilized as a testing tool for evaluating the neural and/or muscular function in vivo it could be used as a post-exercise recovery tool for athletes. ( April 2019) ( Learn how and when to remove this template message)Įlectrical muscle stimulation ( EMS), also known as neuromuscular electrical stimulation ( NMES) or electromyostimulation, is the elicitation of muscle contraction using electric impulses. You may improve this article, discuss the issue on the talk page, or create a new article, as appropriate. The examples and perspective in this article deal primarily with the United States and do not represent a worldwide view of the subject.
