What happens if you put electrodes on your skin?
If you stick a couple of electrodes on your skin and pump an electric current through your tissues, you will tickle your nerves and stimulate interesting sensations and/or some mild muscle contractions, which may temporarily drown out pain or “distract” us from it. More about the biology below.
What is the purpose of nerve conduction test?
The purpose of a nerve conduction test is to determine the health of peripheral nerves by measuring how quickly they conduct electricity. Several pathologies interfere with conduction in distinctive ways. To get the speed, mild electric shocks are applied at very specific locations so that the electricity will mostly zap its way down a specific peripheral nerve axon, to an electrode several inches away.
Is electrical stimulation shallow or deep?
Just as electrical stimulation can be shallow or deep, there’s also electrical stimulation of muscle rather than nerves: electrical muscle stimulation ( EMS ), or neuromuscular electrical stimulation ( NMES ). (They are all “transcutaneous,” but for some reason T-for-transcutaneous is usually only use when referring to nerve stim. There is no “TEMS.”)
How does Tens work?
TENS therapy provides pain relief through two methods, pain gaiting and the release of endorphins. Electrodes send millions of impulses through the nerve endings into the spinal cord and brain, which effectively block the slower pain impulses from connecting.

Pain signals have much smaller nerve diameters when compared to the pleasant impulses which cause them to be overridden by the size and capacity of the signals provided by TENS. This is similar to the body natural instinct to stop the pain. When you hit your elbow, you instinctively start rubbing the injured spot.
What happens when you hit your elbow?

A vaguely related technology is spinal chord stimulation using a long (~30 cm, the last time I saw one many years ago) electrode implanted in the epidural space and activated by a transmitter located outside the body. The electrodes had annular rings on the last 30 mm or so and these could be energized at various frequencies to produce parasthesia (think of the sensation of your foot falling asleep) in the area of the body affected by pain. This is not something used for routine low back pain. It appears to still be used today. Both Boston Scientific and Medtronic make systems according to Dr. Google.

What is a tens device?
Today many people confuse TENS with electrical muscle stimulation (EMS). EMS and TENS devices look similar, with both using long electric lead wires and electrodes. TENS is for blocking pain, where EMS is for stimulating muscles.
Why are tens electrodes not effective?
The use of TENS is likely to be less effective on areas of numb skin or decreased sensation due to nerve damage. It may also cause skin irritation due to the inability to feel currents until they are too high. There's an unknown level of risk when placing electrodes over an infection (possible spreading due to muscle contractions), but cross contamination with the electrodes themselves is of greater concern. TENS should also be used with caution in people with epilepsy or pregnant women; do not use over area of the uterus as the effects of electrical stimulation over the developing fetus are not known.
What is a neuromodulator wrist?
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.
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.
What is the effect of positioning electrodes on opposing sides of the target nerve?
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.
