We hypothesized that change in pain threshold to pressure reflects a generalized change in the pain system affecting both tender and control points.
We assessed 18 tender points and 4 control points using an algometer in 60 patients with generalized fibromyalgia/fibrositis syndrome, 60 patients with localized chronic pain syndromes, and in 60 pain-free subjects.
A significant correlation was found between myalgia scores at tender points and control points in these subjects.
These results suggest that there is a diffuse change in pain modulation in fibromyalgia, as hypothesized, but the tender point is still clinically useful.
我们推测，对压力的疼痛阈值变化反映了疼痛系统的一种全身性变化，这种变化会影响压痛点和对照点。
我们使用压力痛觉计对60例广泛性纤维肌痛/纤维炎综合征患者、60例局限性慢性疼痛综合征患者以及60例无疼痛受试者的18个压痛点和4个对照点进行了评估。
在这些受试者中，压痛点和对照点的肌痛评分之间存在显著相关性。
这些结果表明，正如所推测的那样，纤维肌痛患者的疼痛调节存在弥漫性变化，但压痛点在临床上仍然有用。
