The role of long-term physical exercise on performance and brain activation during the Stroop colour word task in fibromyalgia patients.The Stroop colour word test (SCWT) has been widely used to assess changes in cognitive performance such as processing speed, selective attention and the degree of automaticity.  Moreover, the SCWT has proven to be a valuable tool to assess neuronal plasticity that is coupled to improvement in performance in clinical populations.  In a previous study, we showed impaired cognitive processing during SCWT along with reduced task-related activations in patients with fibromyalgia.  In this study, we used SCWT and functional magnetic resonance imagingFMRI to investigate the effects of a 15-week physical exercise intervention on cognitive performance, task-related cortical activation and distraction-induced analgesia (DIA) in patients with fibromyalgia and healthy controls.
