Individuals with chronic pain find it hard to exercise which often results in an elevated Body Mass Index (BMI). Often these individuals only have mild to moderate structural or biomechanical reasons to explain their pain yet their fear of pain seems to influence their functional capacity before any biomechanical mechanism actually prevents them doing so.A retrospective analysis of 25 individuals with a diagnosis of chronic pain (>3 months duration) to establish anthropometric measures, pain severity and Brief Pain Inventory (BPI) questionnaire including the affective sub-dimension score (REM: relations with others, enjoyment of life, and mood) and the activity subdimension score (WAW: walking, general activity, and work) were assessed.BMI was shown to have a significant effect on the overall daily functional BPI score as assessed using ANOVA, F (4,110) = 29.4, p<0.05, with an effect size w = 0.5. Turkey HSD tests to compare all groups identified a significant relationship between BMI and (i) pain (p<0.05), (ii) REM (p<0.05), and (iii) sleep (p<0.05).These results would suggest that individuals who are overweight and who show higher REM scores on the BPI assessment may benefit from early psychological counselling rather than physical therapy.
