ALL ABOUT TENS:
TENS (Transcutaneous Electrical Nerve Stimulation) is a non-invasive, drug-free method of pain relief that is used for symptomatic relief and management of chronic intractable pain. Transcutaneous means “across the skin”, and TENS relieves pain by sending tiny electrical impulses to underlying nerve fibers, through electrodes placed on or near the area of pain or pressure point.
The frequency of the impulse emitted from your TENS device will determine the type of pain relief that you experience. There are two main groupings of frequencies used in TENS, low (<10 Hz) or high (>50 Hz).
Low frequencies will stimulate the body to release chemicals and endorphins into the bloodstream to help the user feel better. High frequencies are what is known as pain gating. This is the body sending electrical impulses up the spine instead of pain signals whereby masking the pain. Low frequencies will take longer to have an effect but will last longer once the TENS device is removed. High frequencies are fast acting however the effect will tend to diminish quicker once the TENS device is removed.
All iTENS pre-set programs are modulated which means they utilise both low and high frequencies in the same treatment session. This allows the user to benefit from both at the same time. Modulating programs and slight movement of placement will ensure that the body does not build up resistance to the TENS treatment.
