Musculoskeletal system symptoms in patients with COVID-19 and the impact of these symptoms on quality of life

Abstract

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a respiratory disease caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and also affects the musculoskeletal system. OBJECTIVE: This study was conducted to investigate the musculoskeletal symptoms, type of pain and effect on quality of life in patients presenting with pain after COVID-19. METHODS: This prospective, descriptive study included 97 patients aged 18 years or older who were diagnosed with COVID-19 based on a positive polymerase chain reaction test result, with or without musculoskeletal pain prior to COVID-19 infection. Patients who applied to the post-COVID-19 outpatient clinic with the complaint of pain at least 1 month and maximum 1 year after the diagnosis of COVID-19 were included. Patients’ demographic characteristics and musculoskeletal examination findings were evaluated. The patients were examined, and the questionnaire forms were completed. The pain was assessed using the visual analog scale (VAS), the Douleur-Neuropathique-4 (DN-4) questionnaire, while the quality of life was assessed using the Short Form-36 (SF-36) survey. Patients were divided into groups in terms of gender, age, body mass index. Shapiro-Wilk’s test, the independent samples t-test and the Mann-Whitney U test were used for statistical analyses. RESULTS: The mean age of the patients was 46.5 ± 13.5 years, 30 of them were male. Pain increased in patients with pre-COVID-19 arthralgia and myalgia (p< 0.001). Post-COVID-19 VAS was significantly higher than pre-COVID-19 VAS (7 ± 1.2 vs. 3.2 ± 1.9, p< 0.05). Pre-COVID-19 patients with myalgia had significantly worse SF-36 physical function, social function, pain, general health perception (p< 0.05). The mean scores of females in the SF-36 physical function, pain were significantly worse than males (p< 0.05). According to DN-4, 41 (42.3%) patients had neuropathic pain. There was moderate negative correlation between VAS, DN-4 and SF-36 (p< 0.05). CONCLUSIONS: Arthralgia, myalgia, and neuropathic pain, all of which negatively affect the quality of life, are often observed in the patients infected with COVID-19.
