Widespread pain in fibromyalgia is related to a deficit of endogenous pain inhibition.
The repetitive application of passive motion seems likely to stimulate endogenous pain control systems at several levels of the central nervous system with many studies showing consistent responses of concurrent hypoalgesia, sympathetic nervous system excitation and changes in motor function (Schmid et al 2008), as well as a reduction in spinal hyperexcitability (Sterling et al 2010).
