While individuals with nociplastic pain reported lower perceived physical function and exhibited differences in demographic and psychological factors, pain categories were not significant predictors of objective biomechanical measures after adjusting for age, sex, and BMI. However, pain category was a significant predictor of PROMIS-PF, suggesting that it is more closely associated with perceived functional limitations than with quantitative biomechanical performance.
Archibeck et al. (Sun,) studied this question.
