What is transcutaneous electrical nerve stimulation (TENS) therapy?
To relieve pain, low voltage electrical current is used in transcutaneous electrical nerve stimulation (TENS) therapy. Electrodes are positioned on the skin's surface to transmit electrical impulses through a battery-operated TENS unit. The electrodes are placed at trigger sites or close to the nerves, causing discomfort.
How does transcutaneous electrical nerve stimulation (TENS) work?
Two theories explain the mechanism of action of transcutaneous electrical nerve stimulation (TENS). According to one idea, the electric current alters your feeling of pain by stimulating nerve cells that prevent pain signals from being transmitted. The alternative explanation posits that endorphins, the body's endogenous analgesic agent, are elevated in response to nerve stimulation. Next, the endorphins prevent the experience of pain.
What is transcutaneous electrical nerve stimulation (TENS) therapy used to treat?
TENS treatment has been used to treat acute (short-term) and chronic (long-lasting) pain, and it is currently the subject of research. Among the most prevalent ailments for which TENS has been applied are:
- Osteoarthritis
- fibromyalgia
- tendinitis.
- Bursitis.
- Labor pain.
- Low back pain
- Chronic pelvic pain
- diabetic neuropathy
- peripheral arterial disease.
What are the parts of a transcutaneous electrical nerve stimulation (TENS) device, and how do they work?
The TENS machine, which runs on batteries, is comparable in size to a bit of cell phone. Multiple sets of electrode wires and termination pads are included with the gadget. On one end, the electrodes are connected to the device; on the other, they are fastened to pads measuring around 2 inches by 2 inches. Every pad is applied to your skin in particular locations along nerve pathways that must be treated. It has an adhesive backing. (An acupuncturist may attach the TENS unit to acupuncture needles rather than making direct contact with the skin.)
The apparatus delivers electrical energy pulses. The intensity, frequency, length, and pulse type (burst or continuous) can change. A physician, physiotherapist, or acupuncturist sets and modifies the machine's parameters.
What are the advantages or benefits of transcutaneous electrical nerve stimulation (TENS) therapy?
One non-invasive technique for treating pain is TENS. It can be taken on its own or with over-the-counter or prescription painkillers. For some individuals using TENS therapy, the dosage of medicine may be lowered. Never stop taking your medication or changing the dosage without consulting your doctor.
The TENS unit's portability and small size allow it to be utilized whenever pain treatment is required, whether at home or on the go.
What are the risks and side effects of transcutaneous electrical nerve stimulation (TENS) therapy?
Few side effects of TENS therapy have been found. Rarely, patients have complained of burns at the electrode placement locations. Some individuals may have an allergy to the pad's components or the adhesive used to attach it to their skin; in these cases, their skin may become red, inflamed, or develop a rash. Specific individuals may experience sensitivity or discomfort due to the prickling/tingling feeling produced by the TENS device.
Does transcutaneous electrical nerve stimulation (TENS) therapy relieve pain?
The outcomes of TENS therapy for pain management have been conflicting and need to be clarified. According to specific research, TENS use has been associated with patient pain reduction. In many trials, using TENS to relieve pain was not much more effective than "sham" TENS (placebo); in other studies, the effects were superior to placebo. The ailment being treated, the location of the electrodes on the skin, and the TENS unit's settings (pulse frequency, duration, intensity, and type) can all affect a treatment's effectiveness. Researchers state that additional research is necessary to assess the efficacy of TENS because there are insufficient randomized trials comparing TENS to conventional therapy.
TENS therapy may be provided by acupuncturists, physical therapists, and other medical specialists. TENS units can also be obtained with a prescription. You can buy other electrical stimulation devices over the counter. When utilizing the device, always verify with your physician or other healthcare provider. Pay close attention to the manufacturer's directions.
