A transcutaneous electrical nerve stimulation (TENS) unit is a device that sends small electrical currents to targeted body parts. These currents are used to relieve pain. Some TENS units are designed for use in a hospital or healthcare facility.
Surgeons and their patients are increasingly using alternative methods, such as relaxation techniques and acupuncture, to supplement conventional medicine. A combined approach to pain management is often the best option because it allows the surgeon to tailor pain control methods to each individual patient.any studies have found that TENS is useful in easing pain after surgery, as well as pain related to injuries, such as fractures and sprains. TENS may also be helpful for some chronic pain conditions, particularly low back pain. TENS is generally considered safe.
