Background: An increase in the workload and use of personal protective equipment by healthcare workers was observed during the COVID-19 pandemic. Due to the connections between craniocervical structures, symptoms such as neck pain and temporomandibular symptoms could be influenced by the use of PPE.
Aims: To assess the prevalence of craniocervical pain, sleep quality, physical activity, and depressive symptoms and relationship among craniocervical symptoms in healthcare workers before and during the COVID-19 pandemic in Brazil.
Design: Cross-sectional study.
Participants: Healthcare workers.
Settings: An online questionnaire included a self-report of craniocervical pain intensity [orofacial pain, neck pain, and headache (Numerical Rating Scale)], sleep quality (Pittsburgh Sleep Quality Index), depressive symptoms (Patient Health Questionnaire two items) and physical activity (self-report).
Methods: The sample analysis was performed by descriptive statistics, the paired t-test was used to compare symptoms intensity before and during the pandemic. The relationship between dependent and independent samples was assessed through McNemar test, Pearson's chi-squared test, and Student's independent t-test. A value of p < .05 was adopted as statistical significance.
Results: Overall, 147 participants replied the questionnaires. Headache, neck pain, and orofacial pain complaints increased during the pandemic in healthcare workers (p < 0.001). Craniocervical pain was correlated with poor sleep quality, probable depression, and physical activity during the pandemic (p < 0.05).
Conclusion: Healthcare workers self-reported more craniocervical pain during the COVID-19 pandemic compared to before the pandemic. In addition, poor sleep quality, depressive symptoms, and physical inactivity were associated with craniocervical symptoms during this period.
