Transcutaneous Electrical Nerve Stimulation (TENS)
Transcutaneous Electrical Nerve Stimulation (TENS) is a therapeutic technique that employs low-voltage electrical currents to alleviate pain. A TENS unit is a compact, battery-operated device that delivers these currents through electrodes placed on the skin near nerves, aiming to block pain signals or stimulate the release of endorphins, natural painkillers produced by the body..
Mechanism of Action
- TENS is believed to work through two primary mechanisms: Interrupting Pain Signals: The electrical current stimulates nerve cells, inhibiting the transmission of pain signals to the brain, thereby altering pain perception.
- Releasing Endorphin: The electrical stimulation may increase the production of endorphins, the body’s natural pain-relieving chemicals, enhancing pain relief.
Conditions Treated with TENS
TENS is utilized to manage a variety of acute and chronic pain conditions, including:
- Back pain
- Osteoarthritis
- Fibromyalgia
- Tendinitis
- Bursitis
- Chronic pelvic pain
- Pain from sports injuries
- Endometriosis-related pain
While many people report relief, results can vary. Some individuals may not respond to TENS therapy, so it’s often one part of a broader treatment plan.
How Often Can You Use a TENS Unit?
You can typically use a TENS unit several times a day, for up to 60 minutes per session. But before starting, it’s best to consult your physiotherapist or healthcare provider to ensure proper use and avoid side effects.
Safety Considerations
TENS is generally safe when used correctly. However, avoid using it if you:
- Individuals with epilepsy or a pacemaker should not use TENS.
- Pregnant individuals should consult a doctor or midwife before using TENS.
- Avoid placing electrodes on irritated, broken, infected, or numb skin areas.
- Do not use TENS on the mouth, eyes and chest simultaneously, while sleeping, bathing, or operating machinery.
