One article on PainSci cites Wolfe 1992: Trigger Point Doubts
PainSci notes on Wolfe 1992:
A study of the ability of trigger point experts to find trigger points in patients, with some disappointing results: “Problems with reliability were identified.” Twenty years later, Fred Wolfe describes it more vividly: “These myofascial pain experts were no ordinary examiners. They were the best. They wrote the book, they did the lectures. But, in the end, they could not find or agree on the trigger points. It was a disaster.” (See Travell, Simons and Cargo Cult Science.)
original abstract †Abstracts here may not perfectly match originals, for a variety of technical and practical reasons. Some abstacts are truncated for my purposes here, if they are particularly long-winded and unhelpful. I occasionally add clarifying notes. And I make some minor corrections.
Four experts on myofascial pain syndrome (MFP) performed trigger point examinations and 4 experts on fibromyalgia performed tender point examinations on 3 groups of subjects (7 patients with fibromyalgia, 8 with MFP, and 8 healthy persons) while blinded as to diagnosis. Local tenderness was common in both disease groups (65-82%), but was elicited in a greater proportion of MFP experts' examinations (82%). Active trigger points were found in about 18% of examinations of patients with fibromyalgia and MFP, but latent trigger points were rare in all groups. A more liberal definition of trigger point, however, resulted in a 38 and 23% positive rate among patients with fibromyalgia and MFP, respectively. Taut muscle bands and muscle twitches were common (50 and 30%, respectively) and noted equally in all 3 diagnostic groups. Problems with reliability were identified for taut bands, muscle twitch, and active trigger points. Our data are exploratory and tentative, but suggest that attention to definition and reliability are required to advance our knowledge of these common syndromes.
