TENS (Transcutaneous Electrical Nerve Stimulation)
Learn about TENS (Transcutaneous Electrical Nerve Stimulation) as treatment for chronic pain, Alzheimer's disease and ADHD.
Before engaging in any complementary medical technique, you should be aware that many of these techniques have not been evaluated in scientific studies. Often, only limited information is available about their safety and effectiveness. Each state and each discipline has its own rules about whether practitioners are required to be professionally licensed. If you plan to visit a practitioner, it is recommended that you choose one who is licensed by a recognized national organization and who abides by the organization's standards. It is always best to speak with your primary health care provider before starting any new therapeutic technique.
Transcutaneous electrical nerve stimulation (TENS) involves the passage of low-voltage electrical current to electrodes pasted on the skin. The current is delivered through wires from a small battery-powered power unit. The frequency and intensity of this treatment depend on the specific condition and treatment goals. Accordingly, the electrode pads are placed in various sites on the body. Frequency, intensity, and site of application are believed to be pivotal to achieving optimal effects during and after stimulation.
TENS is most commonly used for pain management. There are different types of TENS:
- Conventional TENS — High- or low-frequency electrical current is applied, often near affected areas.
- Acupuncture-like TENS — Lower-frequency current is used at specific trigger points.
- Auricular TENS — Electrical current is applied to the ear
Electricity has been used medicinally for thousands of years. Stone carvings from ancient Egypt depict electric fish being used to treat pain. In ancient Greece, electrogenic torpedo fish were used to treat arthritis and headache.
There are several proposed explanations for how TENS may work:
- It may affect the nerves that perceive pain or light touch.
- It may interfere with nerve pathways.
- It may alter the natural chemicals (such as encephalins, endorphins, opioids or substance P) that affect the way pain is perceived and transmitted.
None of these mechanisms has been clearly demonstrated in scientific research, and the basis of potential activity of TENS is controversial.
Theories traditionally used to explain acupuncture, such as effects on flow of vital energy, have also been offered to explain TENS. It is sometimes suggested that TENS may affect the cardiovascular system, increasing heart rate and reducing blood pressure.
Scientists have studied TENS for the following health problems:
Dental procedure pain: Several small studies report that various TENS techniques reduce pain and the need for pain medications during dental procedures. TENS may also be useful in relieving pain associated with mandibular fractures. Because of problems with the quality of these trials, this evidence can be considered only preliminary. Better research is necessary to make a strong recommendation.
Knee osteoarthritis" Multiple trials report improvements in knee stiffness, physical performance, range of motion, and pain in patients with knee osteoarthritis treated with TENS. It is not clear that TENS improves walking distance or swelling. Some of these studies are small and are not of high-quality. Better research is needed to make a strong recommendation.
Anesthesia (pain relief during surgery): Auricular TENS is sometimes used in Europe to reduce the need for anesthesia during surgical procedures. There is not enough reliable evidence to make a recommendation.
Alzheimer's disease: A small amount of early research reports that TENS may improve some symptoms of Alzheimer's disease, such as mood, memory and cycles of daily rest and activity. Better studies are necessary to make a conclusion.
Angina (chest pain from heart disease): Several small, brief studies (mostly from the 1980s and 1990s) report benefits of TENS on angina pectoris, but most were not well designed or reported. It has been suggested that TENS may improve exercise tolerance and measures of ischemia but not improve symptoms. People with heart disease or chest pain are advised to seek immediate medical attention from a licensed physician. Many well-studied drugs for heart disease are available. Further study is needed before conclusions can be drawn regarding the effectiveness of TENS in this area.
Ankylosing spondylitis: Early research does not provide enough scientific evidence to draw a firm conclusion about effectiveness.
Back pain: The use of conventional TENS or acupuncture-like TENS in people with low back pain is controversial. Studies have used a variety of TENS techniques and defined back pain in different ways. Multiple trials have been published, but most research is not well designed or reported. Overall, it remains unclear if TENS is beneficial. Better-designed research is needed to make a firm conclusion.
Burn pain: Early research does not provide enough scientific evidence to draw a firm conclusion about effectiveness of TENS for burn pain.
Cancer pain: Early research does not provide enough scientific evidence to draw a firm conclusion about effectiveness of TENS for cancer pain.
Chronic pain: The effect of TENS on chronic pain of various causes and locations is controversial. Multiple studies have been published, and even though they have reported benefits, studies have overall been of poor quality. Better-designed research is needed to make a firm conclusion.
Dysmenorrhea (painful menstruation): Several small studies report that TENS may reduce short-term discomfort and the need for pain medications. However, this research has not been high-quality overall. Better-designed trials are needed to make a firm conclusion.
Headache: Preliminary studies report that TENS may have some benefits in patients with migraine or chronic headache. However, this research has not been high-quality overall. Better-designed trials are needed to make a firm conclusion.
Hemiplegia, hemiparesis (paralysis on one side of the body): Early research does not provide enough scientific evidence to draw a firm conclusion about effectiveness.
Labor pain: The use of TENS for labor pain is controversial. Multiple studies have been published, but even though they reported a reduced need for pain medications, studies have been small, poorly designed and without clear descriptions of results overall. Better-designed trials are needed to make a firm conclusion. It is not clear if passage of electricity using TENS has harmful effects on the fetus.
Local anesthesia during gallstone lithotripsy: Lithotripsy involves the use of sound waves to break up gallstones. Early research does not provide enough scientific evidence to draw a firm conclusion about effectiveness.
Facial pain, trigeminal neuralgia, bruxism (tooth grinding) pain: Several small studies report benefits when TENS is used to treat chronic facial pain of various causes. However, these trials are not well designed or reported, and additional research is needed to make a firm conclusion.
Myofascial pain: Early research does not provide enough high-quality scientific evidence to draw a firm conclusion about effectiveness of TENS for myofascial pain.
Pregnancy-related nausea or vomiting: Early research does not provide enough high-quality scientific evidence to draw a firm conclusion about effectiveness of TENS for pregnancy-related nausea or vomiting.
Neck and shoulder pain: Early research does not provide enough high-quality scientific evidence to draw a firm conclusion about effectiveness of TENS for neck and shoulder pain.
Pain from broken bones, rib fracture or acute trauma: A randomized controlled trial in 100 patients with minor rib fracture showed TENS therapy to be more effective for relieving pain than were nonsteroidal anti-inflammatory drugs or placebo therapy.
Diabetic peripheral neuropathy: Early research does not provide enough high-quality scientific evidence to draw a firm conclusion about effectiveness of TENS for peripheral neuropathy.
Phantom limb pain: Early research does not provide enough high-quality scientific evidence to draw a firm conclusion about effectiveness of TENS in phantom limb pain.
Post-herpetic neuralgia (pain after shingles): Early research does not provide enough high-quality scientific evidence to draw a firm conclusion about effectiveness of TENS in post-herpetic neuralgia.
Postoperative ileus (bowel obstruction): Early research does not provide enough high-quality scientific evidence to draw a firm conclusion about effectiveness.
Postoperative nausea or vomiting: Early research does not provide enough high-quality scientific evidence to draw a firm conclusion about effectiveness.
Postoperative pain: There are multiple studies of TENS being used to treat pain after different types of surgery, including abdominal surgery, heart surgery, lung surgery, gynecologic surgery and orthopedic surgery. Some studies report benefits (less pain, less pain with movement, or less need for pain medications), and others find no improvements. Better-quality research is needed to make a firm conclusion.
Post-stroke rehabilitation: One study on spastic dropped foot in subacute stroke reported that TENS had a beneficial effect. Further research is needed to draw a firm conclusion about effectiveness.
Rheumatoid arthritis: A small number of studies report improved joint function and pain in rheumatoid arthritis patients treated with TENS. However, this research is not well designed or reported, and better studies are needed to make a clear conclusion.
Skin ulcers: Early research does not provide enough high-quality scientific evidence to draw a firm conclusion about effectiveness.
Spinal cord injury: Early research does not provide enough high-quality scientific evidence to draw a firm conclusion about effectiveness.
Temporomandibular joint pain: Early research does not provide enough high-quality scientific evidence to draw a firm conclusion about effectiveness.
Urinary incontinence, overactive bladder, detrusor instability: Several small, poorly designed studies exist. Early research does not provide enough high-quality scientific evidence to draw a firm conclusion about effectiveness.
Spinal muscular atrophy (in children): One early study in eight children with spinal muscular atrophy reflected unfavorably on TENS therapy. Early research does not provide enough high-quality scientific evidence to draw a firm conclusion about effectiveness.
Pain during hysteroscopy: A randomized controlled trial in 142 women undergoing hysteroscopy showed that the group who received TENS therapy experienced a significantly lower level of pain. Further high-quality scientific evidence is needed to draw a firm conclusion about effectiveness.
Gastroparesis: One small study of 38 gastroparesis patients receiving percutaneous electrical nerve stimulation (similar to TENS) reported a reduction in nausea and vomiting and a favorable weight gain after 12 months of therapy on the stomach. It is uncertain if these results would be seen with TENS therapy. This early research does not provide enough high-quality scientific evidence to draw a firm conclusion about effectiveness.
Chronic obstructive pulmonary disease rehabilitation: One small randomized controlled trial involving 18 people undergoing rehabilitation for chronic obstructive pulmonary disease (COPD) showed improved muscle strength in the lower extremities as a result of TENS therapy. This suggests that TENS could be useful in adjunct to other components in a rehabilitation program for COPD. This early research does not provide enough high-quality scientific evidence to draw a firm conclusion about effectiveness.
Carpal tunnel syndrome: A small, well-designed trial in 11 patients with carpal tunnel syndrome reported that TENS therapy was an effective treatment for pain. This early research does not provide enough high-quality scientific evidence to draw a firm conclusion about effectiveness.
Soft tissue injury: A randomized controlled trial examined 60 patients with shoulder tendonitis and the effect of TENS and shock-wave therapy on pain. This study showed shock-wave therapy to be more effective than TENS for this condition. Another randomized trial evaluated burst TENS in Achilles tendon injuries. TENS appeared to be beneficial after suture of the Achilles tendon. Further research is needed to confirm these results.
Multiple sclerosis: In a small randomized controlled trial, patients with multiple sclerosis treated with TENS showed a trend toward improvement. Larger, well-designed studies are needed before conclusions can be drawn.
Intermittent claudication: A small randomized controlled trial suggests chronic electrical muscle stimulation may be beneficial for the relief of intermittent claudication symptoms. Further evidence is needed before drawing a firm conclusion.
Attention-deficit hyperactivity disorder (ADHD): A small randomized controlled trial found a moderate benefit in children with ADHD, but further research is warranted before a firm conclusion can be drawn.
Cognitive impairment: Preliminary evidence reports improvements in mood and mild cognitive impairment in elderly patients who do not suffer from Alzheimer's disease or early dementia. However, this early research does not provide enough high-quality scientific evidence to draw a firm conclusion about effectiveness.
Knee replacement pain: Preliminary evidence has found TENS not to relieve postoperative pain after knee replacement. Further research is needed to confirm these results.
TENS has been suggested for many uses, based on tradition or on scientific theories. However, these uses have not been thoroughly studied in humans, and there is limited scientific evidence about safety or effectiveness. Some of these suggested uses are for conditions that are potentially life-threatening. Consult with a health care provider before using TENS for any use.
Carpal tunnel syndrome
Enhanced blood flow in the brain
Enhanced blood perfusion of the uterus and placenta
High blood pressure
Irritable bowel syndrome
|Menstrual cramps |
Muscle strain or pain
Myofascial pain dysfunction syndrome
Pain medication adjunct
Repetitive strain injuries
Sickle cell anemia pain
Skin flap ischemia (during plastic surgery)
Sphincter of Oddi disorders
Tinnitus (ringing in the ear)
In general, TENS is reported as being well tolerated, although research on safety is limited. Skin irritation and redness are the most common side effects, occurring in up to one-third of people. Electrode paste may cause hives, welts or allergic skin reactions (contact dermatitis). Electrical burns may occur with excessive use or improper technique.
Because there is a risk of burns, TENS should be used with caution in people with decreased sensation, such as people with neuropathy. TENS should not be used in people with implanted medical devices such as cardiac defibrillators, pacemakers, intravenous infusion pumps or hepatic artery infusion pumps. Electrical shock or device malfunction may occur.
There are isolated reports of several other side effects, including fluid buildup in the lung, partial collapse of the lung, loss of sensation, pain or unpleasant sensations (near or away from the site of TENS), increased hair growth, headache, muscle aches, nausea, agitation and dizziness. It is not clear if TENS caused these problems. Seizures have been reported, and TENS should be used cautiously in people with seizure disorders. It is sometimes suggested that TENS may affect the cardiovascular system, increasing heart rate and reducing blood pressure.
Although multiple studies have used TENS for pain relief during childbirth, evidence about its safety is limited, and a theoretical risk of harm to the fetus exists. Elevations in fetal heart rate and interference with fetal heart monitoring equipment have been reported. This technique should not be used unless under the strict supervision of an experienced licensed health care practitioner. Safety of TENS is not established in children.
TENS is most commonly used to manage pain, although it has been recommended or studied for many other medical conditions. Preliminary evidence suggests that TENS may be beneficial in the control of dental procedure pain and knee osteoarthritis symptoms. Other uses of TENS have not been sufficiently studied to draw firm conclusions. Skin reactions may occur. People with implanted medical devices should avoid TENS. TENS should be used cautiously and only under medical supervision in pregnant women, children and people with seizure disorders.
