Associação de fatores psicológicos e qualidade do sono com a dor e incapacidade em indivíduos com ombro congelado

Abstract

BACKGROUND: Frozen shoulder is a condition that cause high levels of pain and functional impairments. Psychological factors such as anxiety, depression, kinesiophobia, self-efficacy, and pain catastrophizing may be associated with pain and disability din individuals with frozen shoulder. OBJECTIVE: To analyze the association of psychological factors (anxiety, depression, kinesiophobia, pain catastrophizing, and self-efficacy) and sleep quality with pain intensity and disability in individuals with frozen shoulder. METHODS: This cross-sectional study was conducted via the Google Meet© platform, with data collected through a structured questionnaire on Google Forms©, involving individuals with frozen shoulder. Pain and disability were assessed using the Shoulder Pain and Disability Index; self-efficacy, using the Pain Self-Efficacy Scale; anxiety and depression, using the Hospital Anxiety and Depression Scale; kinesiophobia, using the Tampa Scale for Kinesiophobia-11; pain catastrophizing, using the Pain Catastrophizing Scale; and sleep quality, using the Pittsburgh Sleep Quality Index. Multiple linear regression analysis was performed. RESULTS: A total of 96 individuals with frozen shoulder were included [72 women (mean age = 53.1 ± 10.8 years; symptom duration (months) = 6.1 ± 4.2)]. Pain self-efficacy and kinesiophobia were significantly associated with disability, explaining 19.4% of the variance (f (2,93) = 12.46, p < 0.000, adjusted R² = 0.194, RMSE = 19.98). Pain self-efficacy and anxiety were significantly associated with pain intensity, explaining 21.2% of the variance (f (2,93) = 13.74, p < 0.000, adjusted R² = 0.212, RMSE = 18.7). Depression, pain catastrophizing, and sleep quality were not associated with disability or pain intensity. Kinesiophobia was not associated with pain intensity, while anxiety was not associated with disability. Kinesiophobia was not associated with pain intensity, while anxiety was not associated with disability. CONCLUSION: Self-efficacy, kinesiophobia, and sleep quality were associated with functional disability, while self-efficacy and anxiety were associated with pain. Higher levels of self-efficacy were related to lower pain and disability scores, whereas higher levels of kinesiophobia and anxiety, as well as poorer sleep quality, were associated with less favorable pain and disability outcomes.
