ScienceDaily (June 3, 2008) -- Fibromyalgia is a chronic pain condition that causes widespread pain and tenderness throughout the body. A University of Michigan study, published in The Journal of Pain, shows that fibromyalgia is associated with central nervous system abnormalities evidenced by patients' elevated sensitivity to auditory and pressure sensations.
The Michigan researchers studied 31 subjects to determine if there is a global central nervous system problem underlying sensory processing in fibromyalgia patients. They noted that few studies have employed different stimuli in consistent ways and levels of intensity to measure pain sensitivities in this patient group. In this study, fibromyalgia patients and normal subjects were exposed to random auditory and pressure stimuli.
