A transcutaneous electrical nerve stimulation (TENS) device is a battery-powered device used to relieve pain by certain people. TENS devices function by sending tiny electrochemical stimulation through electrodes with adhesive pads that are attached to the user’s skin.
These electrical impulses overwhelm the nervous system, impairing its capacity to send pain receptors to the spinal cord and the brain. The same electric signals drive the body to manufacture endorphins, which are natural pain relievers.
Applications
TENS machines can be used to assist treat and manage pain. TENS units may aid in the treatment of the following symptoms:
· Menstrual cramps
· Labor ache
· Postoperative discomfort
· Joint discomfort
· Back and neck discomfort
They may also help with pain caused by the following conditions:
· Endometriosis
· Arthritis
· Sports-related injuries
· MS (multiple sclerosis)
· Fibromyalgia
· Damage to the spinal cord
The settings of a TENS device allow patients to give an appropriate amount of pain alleviation. This may be accomplished by modifying the following elements of the electrical current:
· Strength: The user may vary the strength of the electrical impulses using a dial.
· The amount of electrical pulses in a second is referred to as the frequency. High-frequency (HF) pulses, which extend from 80 to 120 cycles per second, may aid in the management of acute pain.
· The duration of each pulse is the number of microseconds that now the electricity reaches the skin.
Benefits of Tens Machines
TENS is a therapeutic way of pain relief. People who get pain relief via TENS may be able to cut back on pain drugs, some of which might be addictive or have negative side effects. TENS units are also beneficial since they are small, portable, and typically unobtrusive. Individuals can keep a TENS unit in their wallet or clip it to their belts to enjoy instant pain relief all day long.
Potential Adverse Effects
Most people are safe to use a TENS device and will not suffer any adverse effects. However, the electric signals produced by a TENS unit may induce a humming, stinging, or tickling sensation feeling that some individuals may find unpleasant.
The sticky pads may cause allergic reactions in some persons. Anyone who has skin rashes and irritation can use hypoallergenic products instead. The electrodes must never be placed at the front of the collarbone or the eyes.
Placing electrodes on the shoulders might cause blood pressure to drop and spasms. When used on the eye, the sensors might raise intraocular pressure and perhaps cause harm.
Due to a dearth of strong scientific clinical studies, research on utilizing a TENS unit for palliative care has so far generated mixed results. Some study shows that TENS therapy helps reduce pain. Understanding how these variables influence TENS might help individuals utilize it more efficiently.
However, before using TENS as a treatment option or in conjunction with other ways of pain management, it is essential to consult with a doctor. TENS units may be purchased at various pharmacies and online.
