Predictors of Post-COVID-19 Functional Status Scale in hospitalized patients recovering from SARS-CoV-2 infection

Abstract

Objective The study aimed to investigate whether peripheral and inspiratory muscle strength and architecture, functional capacity, functional mobility, fatigue and health-related quality of life (HRQoL) are predictors of the PCFS scale score in patients with post-COVID-19 syndrome who were hospitalized. Design A cross-sectional study included 69 patients (53.3 ± 13.2 years, 36 men) with post-COVID-19 syndrome. The following outcomes were assessed: peripheral (dynamometry) and inspiratory (manovacuometry) muscle strength, muscle architecture (ultrasound), functional capacity (six-minute walk test), functional mobility (Timed Up and Go), fatigue (Functional Assessment of Chronic Illness Therapy), HRQoL (36-item Short Form Health Survey) and functional status (PCFS scale). Results Functional mobility (β = 0.573; P < 0.001), vastus intermedius echogenicity (β = -0.491; P = 0.001), length of stay (β = 0.349; P = 0.007) and female sex (β = 0.415; P = 0.003) influenced the PCFS scale. Conclusion Functional mobility, muscle quality of the vastus intermedius, length of stay and female sex influence the PCFS scale score in this population. It is noteworthy that functional mobility is an independent predictor of PCFS scale.

Long COVID Clinical Severity Types Based on Symptoms and Functional Disability: A Longitudinal Evaluation

“…C19-YRS gives scores in three domains: symptom severity (SS), functional disability (FD), and overall health (OH). There are other condition-specific and generic instruments also being used to characterize LC [13][14][15].…”
