ABSTRACT=The acute clinical repercussions of SARS-CoV-2 infection have been widely studied. However, the possible late repercussions of long COVID have not yet been well defined in the literature. Objectives: To identify the presence of pain and Musculoskeletal disability in patients with Long COVID and also to identify predictive factors for pain intensity in this population. Methods: In this cross-sectional and retrospective observational study individuals with Long COVID symptoms were included. It was collected musculoskeletal disability measures, data from patient-related outcome measures and variables from a COVID-19 outpatient service database. Associations and sub-group analyses were performed considering the variables pain, disability and hospitalization. Linear regression was performed to identify predictive factors for pain intensity in Long COVID patients. Results: We evaluated 195 patients and most of them (57%) presented musculoskeletal pain in one area of the body. Pain sub-group presented worse disability indices and worse clinical course during hospitalization. Hospitalized patients presented worse disability indices comparing to non-hospitalized. Significant correlations were found between pain and days of non-invasive oxygen support (r=0.21; p=0.003); days in intensive care unit (r=0.22; p=0.002) and days in invasive mechanical ventilation (r=0.35; p=0.001). Hospitalized individuals showed a higher chance of presenting late musculoskeletal pain (OR=1.42: 95%CI 1.09-2.04). Days in intensive care unit (β=0,234: P=0,001) and days in invasive mechanical ventilation (β=0.764: P=0.001) were predictors of pain intensity [F(2,192)=18.559; R 2 =0.231; p=0.001]. Conclusion: Individuals with Long COVID presented musculoskeletal pain and disability. Hospitalized patients showed a greater chance of having musculoskeletal pain. Days in intensive care unit and days in invasive mechanical ventilation were predictors of late musculoskeletal pain intensity.
