OBJECTIVE: To test the hypothesis that joint hyperlaxity can play
some role in the pathogenesis of pain in primary fibromyalgia.
METHODS: A total of 66 women with fibromyalgia (according to
the 1990 American College of Rheumatology criteria) and 70
women with other rheumatic diseases were examined for joint
laxity based on 5 criteria (The Non- Dominant Spanish
modification). Individuals meeting 4 or 5 criteria were
considered to be hyperlax.
RESULTS: Joint hyperlaxity was
detected in 18 (27.3%) of the patients with fibromyalgia and 8
(11.4%) of those with another rheumatic disorder. The
statistical analysis revealed significant differences (P <
0.05) between both groups.
CONCLUSION: The results of this
study suggest that joint hypermobility and fibromyalgia are
associated. Joint hyperlaxity may play a prominent role in the
pathogenesis of pain in fibromyalgia.
