Things To Consider Before Buying TENS Unit

Things To Consider Before Buying TENS UnitTENS is an acronym that stands for Transcutaneous Electrical Nerve Stimulator (TENS). It is a non-surgical and drug-free method of relieving pain. A TENS Unit is commonly used to provide some relief for arthritis, back pain, or knee pain. Apart from these, it is also a preferred “pain relief” choice to relieve some pains endured during labor, period cramps, or even migraine.

The machine generates an electric impulse, similar to how our brain sends and receive signals to and fro the body’s nervous system. Because of this similar characteristics, there are two theories on how the TENS unit is capable of reducing pain. These are the gate theory and endorphin stimulation.

The gate theory simply states that the electric impulses sent out by the TENS machine block the pain signals before it reached the brain’s “gate.” The theory suggests that the signals sent by the machine move quicker than the pain signals – allowing the electric signals from the TENS machine to reach the brain before the pain signals. It will then block the pain signals’ entry to the “gate.” On the other hand, the endorphin stimulation theory suggests that the TENS machine stimulates endorphin production in our body. Endorphins are our body’s natural morphine or “feel good hormones.” The endorphins will then block the pain signals, to provide instant relief.
