EMS devices, or Electrical Muscle Stimulation devices, are tools that use electrical impulses to stimulate muscle contractions. They are commonly used in physical therapy, rehabilitation, and fitness training to help improve muscle strength, reduce pain, and enhance recovery. These devices typically consist of electrodes placed on the skin, which deliver controlled electrical signals to the underlying muscles. EMS devices can be beneficial for athletes looking to enhance performance, as well as for individuals recovering from injuries or surgeries. They are often used in conjunction with other therapies for optimal results.
