Reliability of TrP in Fibromyalgia

Reference:Wolfe F, et al. The fibromyalgia and myofascial pain syndromes: a preliminary study of tender points and trigger points in persons with fibroniyalgia, myofascial pain syndrome and no disease. J Rheumatol 1992; 19:944-51.

This study involved a group of MDs with “expertise” in myofascial pain syndrome (MFP) and fibromyalgia who performed trigger point (TrP) examinations on 3 groups of subjects (fibromyalgia, MFP, and healthy persons) while blinded to their diagnosis.

Taut muscle bands were noted in 50% of the subjects and muscle twitches were noted in 30% of the subjects …but equally in all 3 groups (including the asymptomatic group!).

The study basically showed poor reliability in identifying taut bands, muscle twitch, and active TrP in patients with fibromyalgia or myofascial pain syndrome.

I find it amazing that “experts” in the field of myofascial pain were unable to detect active TrPs …likely because they were blinded and therefore unbiased to the patients’ diagnosis!
