Brain Activity During Fast Motor Task is Impaired in Patients with Fibromyalgia, Study Suggests
The activation of the motor cortex, a region of the brain responsible for coordinating movement, is dysfunctional in patients with fibromyalgia, a study shows. The study, titled “Motor Cortex Function in Fibromyalgia: A Study by Functional Near-Infrared Spectroscopy,” was published in the journal Pain Research and Treatment. Patients with fibromyalgia (FM) experience widespread muscle pain, fatigue, sleep disturbance, cognitive impairment, and other physical and psychological symptoms. While the cause of FM remains unclear, most experimental evidence suggests that it may be due to a central failure in pain regulation and an abnormal response to pain stimuli. There is some evidence that motor function is also impacted in FM. Studies have shown that patients with chronic pain experience changes in motor performance, and reduced motor coordination and force. However, definitive evidence is lacking about how the motor cortex functions in FM patients compared with healthy subjects. Measuring brain hemodynamic activity — blood flow and metabolic changes in brain tissue — during the performance of a motor task is considered a good measure of motor cortex activation. One way to measure this activity is through the use of Functional Near-Infrared Spectroscopy (fNIRS), a noninvasive technique that allows a real time detection of blood flow and metabolism changes in tissue. In the study, researc
