RESUMO
Background: Fatigue and muscle weakness are common complaints in COVID-19 survivors. However, little is still known about the skeletal muscle qualitative and quantitative characteristics after hospitalization due to moderate and severe COVID-19. Objectives: To assess rectus femoris and vastus intermedius muscle thickness (MT) and rectus femoris echo intensity (EI) and to establish its association with demographic, clinical, functional, and inflammatory parameters in long COVID patients after hospital discharge. Methods: Cross-sectional study with 312 COVID-19 patients (53.53% male; age: 54.59 ± 13.50 years), with a laboratory-confirmed diagnosis of COVID-19. Patients were assessed 3-11 months after hospital discharge. We evaluated MT of the right rectus femoris and vastus intermedius and EI of the right rectus femoris using a portable ultrasound system, 6-13 MHz, broadband linear transducer. We corrected EI using the subcutaneous fat thickness. Ultrasonographic parameters were tested in association with demographic (sex and age); functional (Handgrip strength measurement, Timed Up and Go, 1 min Sit-to-Stand test, EuroQoL-5 Dimensions-5 Levels, World Health Organization Disability Assessment Schedule (WHODAS 2.0), Post-COVID-19 Functional Status, Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT), Medical Research Council (MRC) sum score, Borg Dyspnea Scale, MRC Dyspnea score, Visual Analogue Scale (VAS), Epworth Sleepiness Scale, Insomnia Severity Index, Functional Independence Measurement (FIM), and Functional Oral Intake Scale); clinical (length of hospital stay, intubation, and presence of comorbidities such as systemic hypertension, diabetes, obesity, chronic obstructive pulmonary disease, asthma), and inflammatory data assessed by the C-reactive protein and D-dimer serum concentrations. Results: Rectus femoris MT was associated with age, handgrip strength, Epworth Sleepiness Scale, and subcutaneous fat thickness (r2 = 27.51%; p < 0.0001). Vastus intermedius MT was associated with age, pain intensity, handgrip strength, Epworth Sleepiness scale, FIM, and time since hospital discharge (r2 = 21.12%; p < 0.0001). Rectus femoris EI was significantly associated with the male sex, TUG, Epworth Sleepiness Scale, and C-Reactive Protein levels (r2 = 44.39%; p < 0.0001). Mean MT of rectus femoris and vastus intermedius are significantly different (p < 0.001). Conclusion: After hospital discharge, long COVID patients present qualitative and quantitative skeletal muscle characteristics associated with a combination of demographic, clinical, and functional parameters.
RESUMO
COVID-19 has motor, cognitive, psychological and nutritional consequences that require rehabilitation. Objetive: To describe the outpatient rehabilitation program developed at the Instituto de Medicina Física e Reabilitação do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. Method: We collected sociodemographic and clinical data of 12 adults with laboratory-confirmed COVID-19, severe and critical, who needed hospitalization in the acute phase. Functional assessments included Functional Independence Scale (FIM), EQ-5D-5L, World Health Organization Disability Assessment Schedule (WHODAS 2.0), Post-COVID-19 Functional Status scale (PCFS), Medical Research Council (MRC) dyspnea scale, visual analog scale (VAS) for pain, Douleur Neuropathique 4 (DN-4), Epworth sleepiness scale, Insomnia Severity Index, Montreal Ontario Cognitive Assessment (MoCA), Depression, anxiety and stress scale (DASS-21), nutritional assessment, Timed Up and Go test, 10-meter walking test (10 MWT), handgrip strength, MRC sum score, musculoskeletal ultrasound of the thigh.The outpatient rehabilitation program included electrical and musculoskeletal inductive magnetic stimulation, extracorporeal shockwave treatment, isokinetic exercises, emotional approach, cognitive stimulation, occupational performance stimulation, nutritional guidance, and educational program by COMVC mobile application. Individualized program was delivered twice a week until pre-stablished discharge criteria was achieved. Results: VAS and TUG presented statistically significant improvements (p <0.001). PCFS, FIM, handgrip strength, 10 MWT and DASS-21 anxiety presented slopes in the direction of improvement. Conclusion: The optimized, intensive, interdisciplinary and short-term outpatient rehabilitation program improves pain, mobility and anxiety in long COVID patients.
A COVID-19 tem consequências sensório motoras, cognitivas, psíquicas e nutricionais que necessitam de reabilitação. Objetivo: Descrever o programa de reabilitação ambulatorial desenvolvido no Instituto de Medicina Física e Reabilitação do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, otimizado, intensivo e de curta duração. Método: Obtivemos informações sociodemográficas e clínicas de 12 adultos com diagnóstico laboratorial de COVID-19, grave e crítica, que necessitaram de hospitalização na fase aguda. Avaliações funcionais: Escala de Medida de Independência Funcional (MIF), EQ- 5D-5L, World Health Organization Disability Assessment Schedule (WHODAS 2.0), Post- COVID-19 Functional Status scale, Medical Research Council (MRC) dyspnea scale, escala visual analógica (EVA) para dor, DN-4 (Douleur Neuropathique 4), escala de sonolência de Epworth, Índice de Gravidade da Insônia, Montreal Ontario Cognitive Assessment (MoCA), escala de Depressão, ansiedade e estresse (DASS-21), avaliação nutricional, Timed Up and Go, teste de caminhada de 10 metros, teste de preensão palmar, MRC sum score, ultrassonografia musculoesquelética da coxa antes, durante e após programa de reabilitação ambulatorial. Este incluiu estimulação magnética indutiva e elétrica musculoesquelética, tratamento por ondas de choque extracorpóreas, exercícios isocinéticos, abordagem emocional, estimulação cognitiva, estimulação do desempenho ocupacional, orientação nutricional e programa educacional por aplicativo COMVC. O tratamento foi realizado duas vezes por semana até atingir os critérios de alta pré-estabelecidos. Resultados: VAS e TUG proporcionaram melhora estatisticamente significante (p <0,001). PCFS, MIF, Handgrip, 10 MWT e DASS-21 domínio ansiedade apresentam tendências de melhora. Conclusão: O programa melhora a dor, mobilidade e ansiedade em pacientes com COVID longa.
