Portable EMS Stimulator Machine
What is EMS? Electronic muscle stimulation (EMS) is a physical therapy and fitness technique. Like TENS, it involves a machine that transmits electrical impulses through electrodes that are applied directly to your skin. Unlike TENS, though, the electrodes from an EMS machine are applied to key muscle groups. A common muscle group EMS is used on is the quadriceps after knee surgery. The electrical signals trigger repeated contractions (tightening) of the muscles. The contractions can be short and frequent or long and sustained. This process is not all that different from the voluntary muscle contractions associated with strength training. EMS devices are used to “jumpstart” muscle contractions otherwise known as neuromuscular re-education. They may be found in fitness centers, as well as in physical therapy and rehabilitation clinics. Many EMS devices are also designed and sold for at-home use. The electrical impulse from an EMS device is stronger than that from a TENS machine. An EMS
