The purpose of the present trial was to evaluate semi-standardized
acupuncture efficacy in migraine prophylaxis. Twenty-eight subjects with
migraine were randomized to the real or sham acupuncture groups.
Semi-standardized and standardized minimal acupuncture were used,
respectively, in the two groups of patients. They were all treated with 16
acupuncture sessions in 12 weeks. Both groups exhibited similar reductions
in: percentage of patients with reduction of migraine>or=40% and >or=50%
regarding frequency of migraine attacks, days with migraine, frequency of
migraine attacks, average duration of a migraine attack, rate of rescue
medication used, average headache severity rate and other parameters
compared with the baseline period. Associated symptoms, such as nausea and
vomiting, also showed equal estimates in both groups. These findings showed
that semi-standardized acupuncture shows no difference from sham acupuncture
in preventing migraine attacks.

Me parecen interesantes estos estudios que demuestran que no hay diferencias
entre acupuntura y falsa acupuntura, ya en los libros de texto de medicina
(Tratado de Fsisiologia Médica; Guyton-Hall-Ed. McGraw Hill) se explica que
la estimulación periférica de los receptores del dolor tiene un efecto
analgésico moderado porque activa a vias (o circuitos) que inhiben el dolor.
El mismo efecto tiene la estimulación eléctrica transcutánea (TENS) y es
menos agresiva y arriesgada que los pinchazos de los acupuntores.
