Abstract: This paper describes the modern punctate transcutaneous electrical nerve stimulation (PuTENS) on the basis of the theory of acupuncture. This non-invasive form of therapy can often be used as a substitute for needle acupuncture. The point of stimulus is the major criterion. A clear differentiation betweeen stimulation of genuine acupuncture points and placebo points is therefore possible. During a migraine attack, 60 patients were given a placebo treatment with PuTENS and, 15 minutes later, the appropriate acupuncture points were stimulated. Evaluation of therapy was by means of thermography and visual analogue pain scale. A digital handpyrometer infrared camera was used to measure the temperature of the frontal and occipital skin. Placebo stimulation was defined as point stimulation 2 cm from an actual acupuncture point. The acupuncture points used were: Li 3, Sp 4,5, K 6,5, St 36, G 41, B 62, P 6, Lu 7, LI 4, SI 3 and TH 5. PuTENS stimulation of the placebo Points (simple blind study) did not have a significant effect. The same patients demonstrated significant changes in their state following the stimulation of the acupuncture points indicated for migraine. The pain was reduced and the skin temperature was normalized. In comparison with the stimulation of genuine acupuncture points, it is assumed that the propagation of the stimulus was less and not as deep when the placebo points were used. Our study shows different results to those of previous authors. This may be due to: 1. The authors had less experience with acupuncture. 2. The relative high placebo potential of invasive needling was not considered. 3. Chronic cases demonstrate a much higher placebo potential (50%) than acute cases.
