|Electronic Face Pain Suppression.||
Generally speaking TENS (Transcutaneous Electrical Nerve Stimulation) has not worked with TN. Of the 900+ members of the American TN Association and the 300+ members of the British TN Association, I have only found two people who claimed that TENS relieved their TN pain.
Historically TENS passed through several stages of development. Originally pulse trains with pulse repetition frequencies of between 10 and 100 Hz. were used, sine, square wave and ramp. Later, frequencies used were related to specific pain control theories, ie 10 Hz. For endorphin secretion and 80—100 Hz. for gate control. I have no data relating to depletion of substance ‘p’, or whatever happens to be the alternative ‘flavour of the month’ theory for pain blocking.
Apart from people who did not realise that they had flat batteries in their TENS units, the biggest limitation of conventional TENS is lack of penetration of the flesh, to the offending damaged nerve endings. Stimulation current MUST pass through the nerve endings at the trigger spots, to be effective....... snip.
