It’s important to watch out for any unproven claims associated with either type of machines.įor instance, although a TENS machine may help with temporary relief of pain, it isn’t a miracle cure.Īnd while an EMS unit may help you tone your muscles, it probably won’t help you magically shed a significant amount of weight. Also, be sure to only consider units that are FDA approved. When shopping, take the time to evaluate the machine’s features, such as:īefore making a purchase, check the seller’s return policy and warranty options. They may be able to recommend a product or, depending on your health status, offer advice on other options. to improve muscle contractions while working outīefore shopping for either device, talk with your healthcare provider or physical therapist.under the direction of a physical therapist.if you are recovering from a knee surgery.If you want to treat pain, a TENS machine might be helpful. An EMS device shouldn’t be used to treat pain, and may cause damage to wound sites and incisions. The electrical impulse from an EMS device is stronger than that from a TENS machine.
Many EMS devices are also designed and sold for at-home use. They may be found in fitness centers, as well as in physical therapy and rehabilitation clinics. What’s an EMS device used for?ĮMS devices are used to “jumpstart” muscle contractions otherwise known as neuromuscular re-education. This process is not all that different from the voluntary muscle contractions associated with strength training. The contractions can be short and frequent or long and sustained. The electrical signals trigger repeated contractions (tightening) of the muscles. A common muscle group EMS is used on is the quadriceps after knee surgery. Unlike TENS, though, the electrodes from an EMS machine are applied to key muscle groups. Like TENS, it involves a machine that transmits electrical impulses through electrodes that are applied directly to your skin. Handheld devices are also available to purchase for at-home use.Įlectronic muscle stimulation (EMS) is a physical therapy and fitness technique.
People use TENS in physical therapy and pain clinics. TENS machines may relieve pain caused by many conditions, including:
However, it will not be used to heal injuries. This means that it will temporarily ease pain while being used. It is important to note that TENS is not curative. It’s not painful, but you might feel a slight tingling or warming sensation where the electrodes meet your skin. These signals interfere with pain regulation.Ī single treatment typically lasts 15 to 40 minutes. The frequency and intensity of these signals can be adjusted as necessary. When the unit is turned on, the electrodes transmit low-voltage electrical signals to your body. The adhesive pads, known as electrodes, are placed directly against your skin. It requires using a small handheld or tabletop device, known as a TENS unit, which is connected via thin wires to adhesive pads. Transcutaneous electrical nerve stimulation (TENS) is a noninvasive pain-relief technique.
