Objective: We sought to correlate habitual physical activity with central sensitization, pain intensity, kinesiophobia, catastrophizing, and the severity of chronic myogenous temporomandibular disorder (TMD).
Methods: This was an observational study. Fifty-five individuals, male and female, aged 18 to 45 years, with pain for at least 3 months (chronic) related to myogenous TMD were included in the study. Myogenous TMD was evaluated by means of the Numerical Rating Scale, Catastrophic Thoughts on Pain Scale, Tampa Scale for Kinesiophobia, Fonseca Anamnestic Index, Central Sensitization Inventory, and habitual physical activity by means of the Baecke Questionnaire (BQ). The Spearman correlation coefficient (rs) was applied to verify the association of the BQ score with the pain variables.
Results: No significant correlations (P > .05) were observed in the total or mean BQ scores (both rs = −0.17 to −0.04), nor in the analyses performed on the occupational (rs = −0.03 to 0.14), sport (rs = −0.16 to 0.01), and leisure domains (rs = −0.16 to −0.02).
Conclusion: Habitual physical activity as measured by the BQ is not associated with pain intensity, catastrophizing, kinesiophobia, central sensitization, or the severity of chronic myogenous TMD.
