Why Quality TENS Electrodes Are Crucial To TENS Use

A TENS unit is a medical equipment that is used as part of pain management by helping block pain signals to the brain. TENS is an abbreviation of the longer term, Transcutaneous Electrical Nerve Stimulation that is primarily used to help ease pain after a medical operation, control joint and muscle pains and even manage chronic pain. The therapy involves utilizing a TENS unit electrode that are attached unto the skin which then emits a very weak electrical current. The current then passes unto the skin and into the nerve endings underneath.

The TENS electrodes are then attached to a TENS Unit which is a small battery powered devise wherein the weak electrical signals are generated. The intensity of the small electrical shock can be controlled on the TENS unit as well as the duration and the frequency of the shock. The electrical current generated by the TENS unit replaces the pain signals that is being sent by the nerve endings unto the brain in a way blocking them. Depending on the degree of the electrical current, a high frequency helps to block pain signals while a low frequency helps in the release of endorphins.  A TENS unit cannot be used by everyone. For instance, those who happen to have pacemakers are not allowed to use TENS therapy since the electrical signal can interrupt the pacemakers function. Those who are sensitive to even the slightest electrical shock are also not allowed.

A TENS unit electrode should be of high quality to get the most out of the electrical charge generated from a TENS unit. The efficacy and effectiveness of the TENS therapy highly depends on the quality of the TENS electrodes since these are the components that are attached unto the skin in pads. The electrodes should be able to transmit the electrical signals being generated by the unit effectively unto the pad ends attached on the skin and down under the nerves for effective stimulation and pain management. Using electrodes of dubious quality might pose unnecessary risks to an individual receiving the treatment and can even damage a TENS unit altogether.
