RecruitingBehavioural interventionEffects of Breathing and Attention Training (BAT) on Pain ModulationThe hypersensitivity of fibromyalgia is associated with abnormal pain modulation within the CNS, but not with peripheral or central sensitization. Many brain areas that contribute to modulation of pain are known, but their testing is complex and expensive. Quantitative sensory testing is easier to perform and repeatable. Therefore, it will be used to evaluate the effects of Breathing Attention Training (BAT) on the hypersensitivity of FM participants. BAT is a form of mindfulness meditation shown to decrease FM symptoms and possibly pain sensitivity. We hypothesize that pain modulation of chronic pain patients is improved by BAT.
