What is a TENS Unit and How Does it Work?

When it comes to ailments like gout, arthritis, sciatica, in addition to in postoperative patients, and women in labour, pain control poses a substantial challenge. Methods used for pain relief contain analgesics including non-steroidal anti inflammatory medications (NSAIDs), acetaminophen, antidepressants, opioids, etc., in addition to healing exercises and electropathy.

What is a TENS Unit and How Does it Work?

Electropathy entails using electric signals as a component of health therapy. This is usually accomplished through the use of electric devices designed to provide electrical impulses at acceptable prices. A TENS (Transcutaneous Electrical Nerve Stimulation) device is just one such apparatus designed to excite the nerves and supply relief from pain. It’s a battery-operated, mobile, and patient-wearable apparatus.


The truth is that electric stimulation will help to control pain was understood since ages. Nevertheless, it was just in the 1970so a wearable apparatus capable of delivering low-risk electric signals was devised. This system is referred to as the Transcutaneous Electric Nerve Stimulation(TENS) unit. It may send electric signals throughout the skin and stimulate the nerve pathways such that the feeling of pain becomes blocked.

A TENS device has three big parts:

Electrode pads:  Glue pads which may be connected to the skin close, or above the painful area.
leads Wires that conduct electrical signals in the stimulator device to the electrodes.
Stimulator apparatus: The apparatus that produces and delivers electrical signals in a fixed intensity.

The stimulator of the TENS device creates electrical signals that are conducted with the prospects and moved via the skin from electrode pads.) Based upon the underlying condition, the intensity of pain, in addition to some other special conditions, the seriousness, and frequency of these signs can be put together with controls over the stimulator device. Two standard forms of electric signals generated via a TENS unit help to restrict the feeling of pain.

All these are:

1) Low-intensity, High-frequency Impulses

The feeling of pain normally occurs because of a pair of electric impulses created by the pain receptors within the skin in addition to visceral organs. These impulses are transmitted to the brain by nerve pathways linked to the pain receptors. When these impulses reach the mind, the person experiences pain. These traveling faster than the organic pain impulses of their human body. Because of this, the impulses in the TENS unit reevaluate the pain impulses and get to the brain quicker. The mind can process only a limited amount of impulses. So the artificial instincts that achieve first are processed along with the lagging pain relievers that reach the mind afterward aren’t. Therefore, the feeling of pain is obstructed. These endorphins are accountable for the sense of overall well-being. The delivery of high-intensity electric signals via a TENS device is believed to activate the release of endorphins and thus relieving the feeling of pain.

A TENS device is usually suggested for postoperative sufferers, pain relief through puberty, neck pain, and joint pain in people suffering from arthritis and gout, etc..) Its efficacy in relieving labor pain and lower back pain is debated and believed to function as a placebo. A TENS unit has to be employed by people with implanted devices such as pacemakers and defibrillators, in addition to during pregnancy, just after consulting with the physician. For many others also, it’s always a good idea to seek advice from the proper medical practitioner before resorting to using a TENS device or some other procedures of pain control.
