Different measures of functional status and fibromyalgia were moderately correlated among themselves (p<0.001). No correlation of functional status measures with fibromyalgia measures was statistically significant (unadjusted p>0.05). The observed associations with pain thresholds and regression coefficients showed the same pattern; the correlations were near-zero. The regression model for average standardised cold pain threshold indicated higher WPI scores and lower SSS scores to be associated with higher cold pain thresholds when considering all other factors constant. The regression model for average standardized hot pain threshold indicated worse 6MWT results, higher BBS scores, higher WPI scores and lower SSS scores to be associated with lower hot pain thresholds.

IS THE GRADE OF THERMAL PAIN SENSITIVITY LINKED TO FUNCTIONAL STATUS IN PATIENTS WITH FIBROMYALGIA?
