Características associadas a desempenho funcional comprometido a partir do teste sentar e levantar de 1 minuto em indivíduos com DPOC

Abstract

Introduction: Chronic Obstructive Pulmonary Disease (COPD) can cause systemic, physical and functional complications. Impairment in functional performance can be identified with simple tests such as the 1-minute sit-to-stand (1MSTST). Objective: To analyze characteristics associated with impaired functional performance identified by the 1MSTST in individuals with COPD. Methods: This is a cross-sectional study that included individuals followed at the Pulmonology outpatient clinic of a university hospital, with a clinical diagnosis of COPD, aged ≥40 years. Data collection was carried out using an assessment form in which personal and clinical data were obtained, and simple physical function tests were carried out, including the 1MSTST. The individuals were separated into two groups, one with >50% of predicted repetitions and the other with <50% of predicted repetitions, based on a reference equation for the 1MSTST, and sociodemographic, anthropometric and clinical characteristics were compared between the groups. Results: 55 individuals were included, 53% male, with a mean age of 70 ± 9 years. Patients with compromised functional performance had lower body mass index (BMI) and forced expiratory volume in one second (FEV1). There was no difference in age, sex, Charlson Comorbidity Index, or symptom-related outcomes between groups. Conclusion: Around 50% of patients had compromised functional performance. These individuals had lower BMI and FEV1, despite similar age and sex. Studies with larger samples are needed to confirm these results.
