Epidemiologic, clinical, and experimental evidence points to sex difference
s in musculoskeletal pain. Adult women more often have musculoskeletal prob
lems than do men. Discrepant findings regarding the presence of such differ
ences during childhood and adolescence continue. Biologic and psychosocial
factors might account for these differences. The authors review evidence sh
owing that mechanically induced pressure is more likely to show sex differe
nces than other noxious stimuli and to discriminate between individuals suf
fering from musculoskeletal pain and matched controls. The authors suggest
that a state of increased pain sensitivity, with a peripheral or central or
igin, predisposes individuals to chronic muscle pain conditions, and that t
here are sex differences in the operation of these mechanisms; women are vu
lnerable to the development and maintenance of musculoskeletal pain conditi
ons.
