Microcurrent Electro Therapy (MET)
Although electromedicine has been in existence for well over a thousand years, developments in electronics and new research has seen this technology grow at a terrific rate in recent years. Microcurrent Electro Therapy (MET) is very different than traditional TENS because MET produces its benefits in part on a cellular level. MET has longer lasting effects than TENS. MET is also referred to as Micro-TENS.
The concept of MET is based, in part, on Arndt’s Law, which states that weak stimuli excite physiological activity, whereas medium-strength stimuli will encourage it and strong stimuli will suppress it. |
Micro-TENS and MET are meant to be used directly along a muscle to break down knots and fatigue in muscle. It is a slow frequency (like CES for pain), but the pulses are short. The standard protocol has been to use a fixed frequency of 0.5 Hz. However, Heffernan (1997) found that randomized stimulation from 0.5-3 Hz produced superior results. Our Oasis Pro uses dual-randomized low-frequency stimulation. It is believed that MET delivered at around 500 micro-amps in the 0.5 to 3 Hz range may be most effective for treating pain.
