TENS machines are discreet, lightweight, battery-powered devices that are worn on the body. Wires connect the box to adhesive pads attached to the skin. The body receives tiny electrical pulses that resemble little electric shocks. Some persons who experience particular forms of pain may get relief from this. Many people find them to be quite beneficial. The fact that TENS is often side effect-free and well tolerated is a benefit.

How effective are TENS machines?
Up to now, research studies examining the efficacy of TENS machines have shown different outcomes. Larger-scale research is required to precisely define the function and impact of TENS use. But for some patients, TENS units have shown to be an effective way to relieve pain. Similar to many other types of treatment, the outcome might differ from person to person—even for the same ailment.

How does a TENS machine work?

The TENS machine for pain relief works in the following ways:
● Transcutaneous: It means through the skin.
● Electrical: TENS devices use electrodes applied to the skin to administer tiny electrical pulses to the body. It is believed that TENS units modify the way the brain receives pain signals.
● Nerve: Via the spinal cord and nerves, pain signals are sent to the brain.
● Stimulation: The brain will get fewer impulses from the source of the pain if the TENS machine's mild electrical shocks are effective in blocking pain signals.

How to use a TENS machine?
The recommended course of action is to use a TENS unit only when directed by a physician or other healthcare provider. Not every ailment or kind of pain can be treated with them. The individual using a TENS machine controls it directly. This implies that changing its settings is possible without needing to see a doctor. A machine would normally be used multiple times a day, for fifteen to twenty minutes per session. For detailed instructions, see the section below.

Common uses
● Most often, knee joint arthritis and persistent (chronic) back pain are treated using TENS units.
● They are also frequently used to relieve discomfort during the first few stages of labor, especially while a pregnant woman is still at home.
● Used less often for sports injuries, migraine headaches, menstrual pain, and, very seldom, non-painful illnesses including dementia, sleeplessness, or exhaustion.
● TENS units can be used in conjunction with other therapies or as a stand-alone pain reliever. You may be able to cut back on the number of painkillers you use if you utilize a TENS unit.

TENS devices are often used to treat musculoskeletal pain, which is pain originating from issues with the muscles, joints, and nerves. For these issues, they could be more effective than for headaches, and chest, or abdominal pain.
