RESUMO
PURPOSE: This study aimed to investigate the correlation between mental and physical health-related quality of life and the outcomes of conservative treatment in patients with frozen shoulder (FS). METHODS: This was a two-center retrospective study. It included 84 consecutive patients who underwent a 3-month treatment comprising education, physical therapy, and corticosteroid-anesthetic injections. Changes in range of motion (ROM) and Shoulder Pain and Disability Index (SPADI) scores, measured at baseline and after 3 months, were selected as dependent variables. Data on age, sex, Body Mass Index, duration of symptoms, dominant affected limb, and Short Form-36 (SF-36) subscales were gathered at baseline and investigated as prognostic factors. Backward stepwise regression models were used to identify significant associations. RESULTS: At 3-month follow-up, all the patients showed significant improvement. Higher SF-36 General Health, Mental Health and Social Functioning scores at baseline were associated with a greater beneficial change in ROM and SPADI. In contrast, lower SF-36 Bodily Pain and Role Emotional scores were found to be associated with greater improvement. CONCLUSION: The study findings indicate that the self-perceived mental and physical health of patients have a significant impact on both subjective and objective clinical outcomes and healthcare professionals should take these aspects into account. LEVEL OF EVIDENCE: Prognostic Level II.
Self-perceived mental and physical health could impact the prognosis of subjects affected by frozen shoulder.Healthcare providers should adopt a multi-professional approach to frozen shoulder rehabilitation, integrating the psychological perspective into the management of this condition.For people affected by frozen shoulder, a comprehensive assessment that goes beyond just physical function is recommended.
