From the seminal works of Jon-Kabatt Zinn to new neuroimaging studies the evidence seem to indicate that mindfulness mediation is indeed helpful in the attenuation of pain. A new research review by Zeidan et al (2012) tries to assimilate the empirical knowledge about meditation and pain relief in order to gain an understanding about the possible specificity of mindfulness techniques in pain regulation. ...
