Acupuncture has been a means of treating headaches and migraine since 2002 and is now a World Health Organisation-recognized prophylactic treatment for migraine. Brain activation/de-activation via acupuncture modifies the haemodynamic responses in the brain which may impact the sensorial, cognitive and affective dimensions of pain. Randomized studies on patients suffering from aura-free migraine have shown that the painkilling effect of regular acupuncture sessions on the cerebral substratum, compared with simulated sham-type acupuncture, can reduce the frequency of bouts of migraine, number of days with headaches and also their intensity.
Modifications to the white matter (WM) and grey matter (GM) occur after repeated sessions of acupuncture treatment for pain and these are observable via magnetic resonance imaging (MRI). It is a very sensitive technique and often used to detect functional and structural brain changes.
Since 2002, acupuncture has been employed as a method for treating headaches and migraine. It is recognized by the World Health Organisation (WHO), and is now part of the prophylactic treatments for migraine. Brain activations/de-activation via acupuncture lead to a modification of haemodynamic responses in the brain which may impact the sensorial, cognitive and affective dimensions of pain. Randomized studies on patients who suffer from migraine without aura have shown that the painkilling effect of repeated acupuncture sessions on the cerebral substratum, compared with simulated sham-type acupuncture, make it possible to reduce the frequency of bouts of migraine, the number of days of headaches, and the intensity of the bouts.
Following repeated sessions of acupuncture treatment for pain, modifications occur in the white matter (WM) and in the grey matter (GM) and these may be observed by magnetic resonance imaging (MRI) which is a highly sensitive technique and very often used to detect functional brain changes and/or subtle abnormalities.

40 patients will be randomly assigned to one of two groups (1) The Interventional Group: 20 Patients will receive 5 real acupuncture sessions each spaced 15 days apart. At the first and last sessions of acupuncture, an MRI scan will be performed before and after the acupuncture session and (2) The Placebo Group : 20 patients will receive 5 sham sessions of acupuncture (i.e. using a simulated acupuncture technique) each spaced 15 days apart. At the first and last sham sessions, an MRI scan will be performed before and after the sham acupuncture session.

The patient is unaware of the study (and whether he/she is receiving the placebo or not).
The imager is also unaware of whether the patient has had sham or real acupuncture.
| Sham acupuncture (placebo group) | Other | Sham acupuncture is used as a control in scientific studies to test the efficacy of acupuncture in the treatment of various disorders, in this case, migraine. In this study, the subjects will not know whether they are getting true acupuncture or not. In the placebo group, the acupuncture needles will not actually be inserted into the skin. Placebo needles consisting of a sliding tube and a retractible needle are applied to the acupunture reference point (marked by a pastille stuck on the skin). The patient should not be able to feel the difference between real acupuncture and sham acupuncture. |
