Physical exercise over a long term improves cognitive processing and overall symptoms of fibromyalgia, new research from Sweden shows.
The study, “The role of long-term physical exercise on performance and brain activation during the Stroop colour word task in fibromyalgia patients,” was published in the journal Clinical Physiology and Functional Imaging.
A substantial body of literature has shown that fibromyalgia patients present impaired pain inhibition in the central nervous system. Alterations in brain activation and connectivity are also well-known, including in areas modulating both cognition and pain.
These observations led to the theory that the cognitive complaints in chronic pain patients are caused by the dominance of pain processing over resources that are also needed for cognition — this is called the limited resource theory.
