Pressure pain threshold in pain-free subjects, in patients with chronic regional pain syndromes, and in patients with fibromyalgia syndrome.
We hypothesized that change in pain threshold to pressure reflects a generalized change in the pain system affecting both tender and control points. ⋯ These results suggest that there is a diffuse change in pain modulation in fibromyalgia, as hypothesized, but the tender point is still clinically useful.
