How does a Tens device work?
TENS operates by two main mechanisms: it stimulates competing sensory neurons at the pain perception gate, and it stimulates the opiate response. The mechanism that will be used varies with the type of device.
When was electrical stimulation first used?
Electrical stimulation for pain control was used in ancient Rome, in AD 63. It was reported by Scribonius Largus that pain was relieved by standing on an electrical fish at the seashore. In the 16th through the 18th centuries various electrostatic devices were used for headache and other pains.
What is a wrist neuromodulator?
A wearable neuromodulation device that delivers electrical stimulation to nerves in the wrist is now available by prescription. Worn around the wrist, it acts as a non-invasive treatment for those living with essential tremor. The stimulator has electrodes that are placed circumferentially around a patient's wrist. Positioning the electrodes on generally opposing sides of the target nerve can result in improved stimulation of the nerve. In clinical trials reductions in hand tremors were reported following noninvasive median and radial nerve stimulation.
When was the first tens implanted?
The first modern, patient-wearable TENS was patented in the United States in 1974. It was initially used for testing the tolerance of chronic pain patients to electrical stimulation before implantation of electrodes in the spinal cord dorsal column. The electrodes were attached to an implanted receiver, which received its power from an antenna worn on the surface of the skin. Although intended only for testing tolerance to electrical stimulation, many of the patients said they received so much relief from the TENS itself that they never returned for the implant.
Does Tens affect the brain?
As reported, TENS has different effects on the brain. A randomized controlled trial in 2017 shown that sensory ULF -TENS applied on the skin proximally to trigeminal nerve, reduced the effect of acute mental stress assessed by heart rate variability (HRV). Further high quality studies are required to determine the effectiveness of TENS for treating dementia.
What is tens in medical terms?
TENS is a method of electrical stimulation which primarily aims to provide a degree of symptomatic pain relief by exciting sensory nerves and thereby stimulating either the pain gate mechanism and/or the opioid system. The different methods of applying TENS relate to these different physiological mechanisms.
What is modulation mode in tens?
In modulation mode, the machine delivers a less regular pattern of TENS stimulation in an attempt to reduce or minimise the accommodation effects of regular, patterned stimulation. Machines offer different methods of varying the stimulation pattern – some vary the frequency, some vary the intensity and some vary the pulse duration, and some machines offer a choice between these methods, though the research evidence to date does not favour one variation method over another. This potentially most useful for patients who use TENS for hours a day, if for no other reason than accommodation occurs at a slower rate and therefore less intensity adjustment may be required.
How to use a spinal cord electrode?
In order to get the maximal benefit from the modality, target the stimulus at the appropriate spinal cord level (appropriate to the pain). Placing the electrodes either side of the lesion – or pain areas, is the most common mechanism employed to achieve this. There are many alternatives that have been researched and found to be effective – most of which are based on the appropriate nerve root level : 1 Stimulation of appropriate nerve root (s) 2 Stimulate the peripheral nerve (best if proximal to the pain area) 3 Stimulate motor point (innervated by the same root level) 4 Stimulate trigger point (s) or acupuncture point (s) 5 Stimulate the appropriate dermatome, myotome or sclerotome

Overview
- A TENS unit is a device you can use at home for pain management. TENS stands for transcutaneous electrical nerve stimulation. To use a TENS unit, you place sticky electrodes on the skin around a painful area, such as on the small of your back. When the TENS unit is turned on it delivers a small current through the electrodes to the skin and tissues just beneath it. You are l…
Treatment
- One of the most common forms of electrical stimulation used for pain management is transcutaneous electrical nerve stimulation (TENS) therapy, which provides short-term pain relief. Electrical nerve stimulation and electrothermal therapy are used to relieve pain associated with various conditions, including back pain. Intradiscal electrothermal therapy (IDET) is a treatment …
- If you have chronic or acute pain, your doctor may suggest trying TENS for relief. It is a non-invasive, non-drug choice for relieving pain. It won't work for everyone, and it may not work better than a placebo.
- An alternative approach is to stimulate the A delta (Aδ) fibres which respond preferentially to a much low frequency LF (in the order of 2 - 5 Hz), which will activate the opioid mechanisms, and provide pain relief by causing the release of an endogenous opiate (encephalin) in the spinal cord which will reduce the activation of the noxious sensory pathways. In a similar way to the pain ga…
Mechanism
- Intervertebral discs act as cushions between the vertebrae. Sometimes the discs can become damaged and cause pain. IDET uses heat to modify the nerve fibers of a spinal disc and to destroy pain receptors in the area. In this procedure, a wire called an electrothermal catheter is placed through an incision in the disc. An electrical current passes through the wire, heating a s…
- TENS is thought to disrupt the pain cycle by delivering a non-painful sensation to the skin around the pain site. In essence, TENS modulates the way we process the pain sensations from that area. TENS closes the pain gate, so to speak.
- The type of stimulation delivered by the TENS unit aims to excite (stimulate) the sensory nerves, and by so doing, activate specific natural pain relief mechanisms. For convenience, if one considers that there are two primary pain relief mechanisms which can be activated : the Pain Gate Mechanism and the Endogenous Opioid System, the variation in stimulation parameters us…
Precautions
- 1. If there is abnormal skin sensation, the electrodes should preferably be positioned elsewhere to ensure effective stimulation 2. Electrodes should not be placed over the eyes 3. Patients who have epilepsy should be treated at the discretion of the therapist in consultation with the appropriate medical practitioner as there have been anecdotal reports of adverse outcomes, mo…
- Serious adverse events from TENS are rare. Occasional reports of mild electrical burns with TENS-like devices are due to an inappropriate technique. Some patients experience mild autonomic responses and minor skin irritation beneath electrodes. TENS can interfere with monitoring equipment and should not be placed close to transdermal drug delivery systems.Gui…

Results
- Early studies indicated that some patients may have continued pain relief for up to six months or longer. The long-term effects of this procedure on the disc, however, have not been determined.More studies are needed to compare this treatment to standard therapies and surgery as well as placebo.
- Does TENS relieve chronic pain? Sadly, the jury is still out on this one. A number of researchers have determined that TENS can help control chronic pain. However, most studies show little difference between the TENS unit and the placebo. Like most chronic pain treatments, TENS does not work for everyone. The evidence is better that TENS can help relieve acute pain, with patient…

Research
- A 2014 study set out to provide a critical review of the latest basic science and clinical evidence for TENS. Key findings were...
Function
- Depending on the frequency the TENS unit delivers, the electrical stimulation can also trigger the body to release endorphins. Endorphins act as natural painkillers and help promote a feeling of well-being.
