Validação do Modified Pulmonary Functional Status and Dyspnea Questionnaire e da escala do Medical Research Council para o uso em pacientes com doença pulmonar obstrutiva crônica no Brasil

“…The Medical Research Council (MRC) scale, also validated for use in Portuguese, (27) was used in order to evaluate the sensation of dyspnea during the daily life activities. The scale comprises only five items, and the patient chooses the item which corresponds to the limitation caused by dyspnea in his or her daily life.…”

Objective: To evaluate characteristics of physical activities in daily life in COPD patients in Brazil, correlating those characteristics with physiological variables. Methods: Physical activities in daily life were evaluated in 40 COPD patients (18 males; 66 ± 8 years of age; FEV 1 = 46 ± 16 % of predicted; body mass index = 27 ± 6 kg/m 2 ) and 30 healthy age-and gender-matched subjects, using a multiaxial accelerometer-based sensor for 12 h/day on two consecutive days. We also assessed maximal and functional exercise capacity, using the incremental exercise test and the six-minute walk test (6MWT), respectively; MIP and MEP; peripheral muscle force, using the one-repetition maximum test and the handgrip test; quality of life, using the Saint George's Respiratory Questionnaire (SGRQ); functional status, using the London Chest Activity of Daily Living questionnaire; and dyspnea sensation, using the Medical Research Council (MRC) scale. Results: Mean walking time/day was shorter for COPD patients than for the controls (55 ± 33 vs. 80 ± 28 min/day; p = 0.001), as movement intensity was lower (1.9 ± 0.4 vs. 2.3 ± 0.6 m/s 2 ; p = 0.004). The COPD patients also tended to spend more time seated (294 ± 114 vs. 246 ± 122 min/day, p = 0.08).Walking time/day correlated with the 6MWT (r = 0.42; p = 0.007) and maximal workload (r = 0.41; p = 0.009), as well as with age, MRC scale score and SGRQ activity domain score (−0.31 ≤ r ≤ −0.43; p ≤ 0.05 for all). Conclusions: This sample of Brazilian patients with COPD, although more active than those evaluated in studies conducted in Europe, were less active than were the controls. Walking time/day correlated only moderately with maximal and functional exercise capacity.Keywords: Pulmonary disease, chronic obstructive; Motor activity; Exercise tolerance. ResumoObjetivo: Avaliar as características de atividades físicas na vida diária de pacientes portadores de DPOC no Brasil e sua relação com diferentes variáveis fisiológicas. Métodos: Foram avaliados 40 pacientes portadores de DPOC (18 homens; 66 ± 8 anos; VEF 1 = 46 ± 16 % predito; índice de massa corpórea = 27 ± 6 kg/m 2 ) e 30 idosos saudáveis pareados por gênero e idade quanto às atividades físicas na vida diária, utilizando-se um acelerômetro multiaxial por 12 h/dia durante dois dias consecutivos. Foram ainda avaliados as capacidades máxima e funcional de exercício através do teste incremental máximo e do teste de caminhada de seis minutos (TC6), respectivamente; PImáx e PEmáx; força muscular periférica através dos testes de uma repetição máxima e de força de preensão manual; qualidade de vida através de Saint George's Respiratory Questionnaire (SGRQ); estado funcional através do questionário London Chest Activity of Daily Living; e sensação de dispneia através da escala do Medical Research Council (MRC). Resultados: Os pacientes portadores de DPOC apresentaram menor tempo de caminhada/ dia quando comparados aos idosos saudáveis (55 ± 33 vs. 80 ± 28 min/dia; p = 0,001) e menor intensidade de movimento (1,9 ± 0,4 vs. 2,...

“…On the first day, patients answered the Medical Research Council scale (MRC) 9 and Short-Form 36 questionnaire (SF-36) 10 , and their CRB-65 scores 11 were recorded. Subsequently, patients performed either a spirometry 12,13 or peripheral muscle strength (PMS) test, as well as either the 6-minute walk test (6MWT) 14,15 or the Glittre test (GT) 16 .…”

| Background: Symptoms of fatigue and dyspnea, treatment with oral corticosteroids, high circulating levels of cytokines, and oxidant/antioxidant imbalance in patients hospitalized with community-acquired pneumonia (CAP) could affect the patients' exercise tolerance and peripheral muscle strength (PMS). Objective: To evaluate the functional capacity (FC) of patients hospitalized for CAP and to correlate the FC with length of hospital stay. Method: We prospectively evaluated 45 patients (49±16 years; CAP group) and 20 healthy subjects (53±17 years; control group). They were randomized to perform, on separate days, a 6-minute walk test (6MWT), a test of PMS, and the Glittre test (GT). Additionally, the SF-36 questionnaire and the MRC scale were completed and evaluated. Results: There were significant differences between the groups (CAP and controls) for the 6MWT (381.3±108 vs. 587.1±86.8 m) and GT (272.8±104.3 vs. 174±39 sec). The CAP group also presented worse health-related quality of life (HRQoL) scores, reduced strength (quadriceps and biceps), and higher scores of dyspnea. The time required to perform the GT correlated with the length of hospital stay (r=0.35, P=0.02) and dyspnea (r=0.36, P=0.02). Significant correlations were observed between GT and 6MWT (r=-0.66, P=0.0001) and between GT with the physical functioning domain of SF-36 (r=-0.51, P=0.0001). Conclusions:Patients hospitalized for CAP presented with reduced FC, PMS, and HRQoL during hospitalization. In addition, GT performance was related to the length of hospital stay.Keywords: pneumonia; physical therapy; exercise tolerance; quality of life; muscle strength. HOW TO CITE THIS ARTICLE
