▶Ear acupuncture in the treatment of migraine attacks: a randomized trial on the efficacy of appropriate versus inappropriate acupoints
Auricular acupuncture for acute migraine (n=94).Methods
The research group have piloted a technique called the Needle Contact Test (NCT): tender points on the ear are identified, for example, with the Sedatelec algometer, then a needle is held in contact with each tender point in turn for 10 s – looking for the one which produces the greatest immediate reduction in pain. That is the point chosen for needle insertion. In patients with acute migraine attacks, they found the majority of the points were located on the antero-internal part of the antitragus (area M in figure 1) on the same side of pain, so that limited area was used in this study.
Ninety-four women were recruited in a Headache Centre in the first 4 h of an attack of migraine without aura. In the test (verum) group, tender points were located in area M and a needle held in contact. Any areas that produced a 25% reduction in pain was needled with a semipermanent ASPSedatelec needle.
In the control group, non-tender areas were located in an inappropriate area (sciatic nerve, S in figure 1) with the algometer, and needled in the same way. Changes in pain intensity were measured using a Visual Analogue Scale for the next 24 h.Results
As shown in the figure 2, there was a significant and clinically relevant greater reduction in pain over 24 h in the group needled at the tender points.
