TENS Units offer non-pharmaceutical pain control that may reduce dependency about pain drugs. These include simple for people to deal with and could be worn during everyday escapades like workplace and during recreational escapades. These include inexpensive and non-addictive. They are safe and easy to use without the potential risks connected with surgery or thick duty narcotic drugs. Patients could think clearly without residing a "narcotic fog", thus living more positively and productively. The electric stimulation from TENS machines relieves pain by exciting peripheral nerves through what exactly is termed the gate control system. The gate control theory of pain suggests which inside the spinal cord there is a control system acting as a gate. The Gate Control theory was initially introduced inside 1965 by Melzack and Wall inside their Science article "Pain Mechanisms: A New Theory". The electric impulses from TENS models, according to the theory, represent anon-noxious input. This input suppresses pain by closing the gate to incoming noxious input, like pain from an arthritis back. If the gate is shut by non-noxious stimuli, like which coming from TENS device (transcutaneous electric nerve stimuli), then a body are not able to process the noxious stimuli and pain may be therefore reduced. Here's a more detailed explanation. There are a couple of types of cells inside the part of the spinal cord where alerts come into. One is "inhibitory" as well as the different is "transmission". Transmission cells are activated by incoming alerts and when a important threshold degree is hit, pain starts as the gate starts as well as the brain gets those alerts and processes them as pain. The job of the inhibitory cells is to restrict activation of the transmission cells, thus closing the gate and keeping it shut. The job of a TENS device is to motivate the inhibitory cells and close the gate. TENS machines produce two different actual frequencies under the pain limit which are tolerated by people. This method, they close the gate instead of open it.
