For example, TENS may inhibit (block) pain pathways or increase the secretion of the pain-reducing substances (e.g., endorphins, serotonin) in the central nervous system. There are several possible ways TENS works. The exact mechanism by which it works to reduce or even eliminate pain is still unknown. TENS machines produce an electrical impulse that can be adjusted for pulse, frequency, and intensity. decreased use of pain relievers or other analgesic drugs.To summarize, the benefits from TENS treatment can include: TENS is usually used along with other forms of treatment and pain control such as analgesics, relaxation therapy, biofeedback, visualization or guided imagery, physiotherapy, exercise, massage therapy, nerve block injections, and/or spinal manipulation. Studies show that TENS can significantly reduce the use of analgesics (pain relievers, including narcotic drugs) after surgery. Sometimes TENS is used after surgery for incision or post-operative pain (e.g., joint replacement, cardiac procedures, various abdominal surgeries, or cesarean sections). Athletes with painful acute soft tissue injuries (e.g., sprains and strains) may benefit from TENS treatment. TENS can also be used for muscle soreness from overuse, inflammatory conditions, and both rheumatoid and osteo-arthritis. TENS has been used for people suffering from cancer-related pain, phantom-limb pain (a chronic pain syndrome following limb amputation), and migraine or chronic tension-type headaches. Nerve pain (neuropathy) from conditions such as chronic regional pain syndrome (CRPS) or diabetes may also be managed with TENS. Back pain caused by spine degeneration, disc problems, or failed back surgery is commonly relieved by the use of TENS. TENS can be used for relief of pain associated with a wide variety of painful conditions. In addition to controlling pain, this type of electrical stimulation can also improve local circulation and reduce or eliminate muscle spasm. Pain messages may be altered enough to provide temporary or even long-lasting pain relief. TENS is a noninvasive way to override or block signals from the nerves to the spinal cord and brain. When it is delivered through electrodes or patches placed on the skin, it is called transcutaneous (meaning through the skin) electrical nerve stimulation or TENS for short. It is a form of electrical energy sent in various waveforms to the nerves. Welcome to Advantage Physiotherapy’s guide to Transcutaneous Electrical Nerve Stimulation.Įlectrical nerve stimulation is a treatment for pain that can be used for acute pain (e.g., during labor or after surgery) or for chronic pain (e.g., low back pain).
