TENS Units

Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive, drug-free method of controlling pain. TENS uses tiny electrical impulses sent through the skin to nerves to modify your pain perception. TENS does not cure any physiological problem; it helps control the pain. TENS does not work for everyone; however, in most patients it is effective in reducing or eliminating the pain, allowing for a return to normal activity.

What is TENS and how does it work?

TENS stands for Transcutaneous Electrical Nerve Stimulation. Roughly translated, transcutaneous means to pass through to the skin without breaking it. Simply put, when a TENS unit is turned on, it applies a current of electricity through electrodes into the skin and affected tissue to address chronic pain.

TENS manages your pain by disrupting the pain cycle through electric impulses and, on the correct setting, by helping produce endorphins. Endorphins are your body's way to manage pain by causing an analgesic effect. TENS can also improve your blood circulation, which then helps your body through the healing process. In most patients, TENS is effective in reducing or eliminating pain, allowing you to return to normal activity.

United Medical Source offers portable TENS units to relieve your pain, but not disrupt your day-to-day life. Our portable devices send comfortable impulses through the skin to stimulate your nerves in the affected area.

Warnings and Cautions

Although experts generally consider TENS to be safe, you should consult your physician before using TENS if:

  • You have an implanted electronic device, such as a cardiac pacemaker, implanted defibrillator, or any other metallic or electronic device
  • You are pregnant
  • You have cancer
  • You have heart disease

Electrodes should never be used near the heart, on the front of the thorax (marked by ribs and breastbone), near or on the two large pectoral muscles as it can increase the risk of ventricular firillation and lead to cardiac arrest. Electrodes should not be placed over the eyes, in the mouth, near the genitals, or internally.
