How to Buy a Portable TENS Unit
|
A portable TENS unit is short for transcutaneous electrical nerve stimulation. There are many versions of electrical nerve stimulators such as TENS, Galvanic, Interferrential, and Russian. TENS is the most common type of nerve stimulator people purchase.
If you are considering a portable TENS unit for pain relief, they can be purchased sometimes without a prescription. Some of the conditions a TENS unit can treat are low back pain, arthritis, headaches, joint pain, and several more.
The way TENS work is that the unit sends a electrical pulse to your nerves thereby blocking the pain signals from reaching your brain. Other theories claim that by stimulating the nerves electrically, the brain released endorphins causing natural pain relief.
But when buying a portable TENS unit, you have many to choose from. There are digital units, analog units, single channel, dual channel, and each unit can have several modes and settings.
