Used since the 1970s for pain inhibition in acute as well as chronic pain states, transcutaneous electrical nerve stimulation (TENS) stimulates primary afferents by low-voltage controlled electrical pulses through electrodes applied to the skin. (1) A number of physiological studies have suggested that afferent activity induced by TENS inhibits nociceptive transmission in the spinal cord through presynaptic and postsynaptic inhibitory mechanisms. (2) In addition to studies on pain relief, the effect of TENS on blood flow has been investigated in a number of studies. (3-7) Segmental inhibition of sympathetic vasoconstriction, release of vasodilator peptides from sensory ...
