TI  - Pressure pain thresholds of tender point sites in patients with fibromyalgia and 
      in healthy controls.
PG  - 111-7
AB  - Pressure pain threshold (PPT) is defined as the minimum force applied which 
      induces pain. This measure has proven to be commonly useful in evaluating 
      tenderness symptom. Our aim was to study the intra-examiner reproducibility of 
      PPT measurement, define cutoffs in normal groups, and compare these results with 
      patients with fibromyalgia (FM). Fifty healthy females, 50 healthy males, and 20 
      patients with FM participated in the study. PPTs were assessed for 18 specific 
      tender point sites by a dolorimeter. The intra-individual coefficient of 
      variation determined by a test-retest PPT measurement procedure with 3-days 
      interval reached, respectively, 17% and 13% in healthy females and males, versus 
      24% in patients with FM. PPTs were significantly lower in healthy females than in 
      healthy males (p<0.01). Statistical analysis failed to show any differences 
      between the dominant and nondominant side for both normal groups. PPTs were lower 
      over all examined areas in patients with FM than those obtained in healthy 
      females (p<0.000). Lower cutoff levels were calculated from normal values for all 
      specific tender point sites. On average, 14 tender point sites in patients with 
      FM were under the established lower cutoffs. In conclusion, pressure pain 
      sensitivity was influenced by the anatomical localization of tender point and 
      gender differences. Lowest PPTs were localized in trapezius, occiput, anterior 
      cervical, and second rib. The reduction of total tender point score in patients 
      with FM averaged 60% comparatively with normal values. PPT reproducibility and 
      discrimination between the two groups were optimal for the gluteal and knee 
      sites.
