Widespread pain in fibromyalgia is related to a deficit of endogenous pain inhibition
N Julien, P Goffaux, P Arsenault, S Marchand - Pain, 2005 - Elsevier
A deficit of endogenous pain inhibitory systems has been suggested to contribute to some
chronic pain conditions, one of them being fibromyalgia. The aim of the investigation was to
test whether endogenous pain inhibitory systems were activated by a spatial summation
procedure in 30 fibromyalgia, 30 chronic low back pain, and 30 healthy volunteers who
participated in a cross-over trial (two sessions). Each session consisted of visual analog
scale ratings of pain during the immersion of different surfaces of the arm in circulating …
