Correlation between functional capacity and health-related quality of life in COPD: a case series

Abstract

Objective: To correlate functional capacity test scores from chronic obstructive pulmonary disease (COPD) subjects with their functional state as assessed by health-related quality of life questionnaires (one respiratory disease-specific [SGRQ] and one generic questionnaire). Materials and methods: Study of a case series of 8 COPD patients. The following tests were performed: 1) Six-minute walk test (6-MWT); 2) Shuttle walking test (SWT); 3) Six-minute step test (6-MST); 4) Two-minute sit-to-stand test (STST); and 5) Pegboard and ring test (PBRT). Besides these tests, two health-related quality of life questionnaires were administered: The St George's Respiratory Questionnaire (SGRQ) and the Short Form 36 (SF-36) health survey questionnaire. The statistical analysis was carried out by using the Shapiro-Wilk normality test, while correlations were assessed using Pearson's (parametric data) or Spearman's (non-parametric data) rank tests, withFisioter Mov. 2014 out/dez;27(4):505-14 Cancelliero-Gaiad KM, Ike D, Soave L, Gomes ELFD, Dias FD, Costa D. 506 p < 0.05. Results: The 6-MWT showed strong correlation with the SF-36 scales of physical functioning, general health, vitality, social functioning and mental health. Conversely, the other functional capacity tests showed no correlation with this questionnaire. The SGRQ showed no correlation with any of the tests. Conclusions: The 6-MWT may be a good test to reflect the health-related quality of life of COPD subjects. [P] Keywords: Quality of life. COPD.

Materiais e métodos: Foi realizado um estudo de uma série de casos com oito pacientes portadores de DPOC que realizaram os seguintes testes: 1) Teste de caminhada de seis minutos (TC6'); 2) Shuttle walking test (SWT); 3) Teste do degrau de seis minutos (TD6'); 4) Teste de sentar e levantar-se da cadeira em dois minutos (TCad-2min); e 5) Pegboard and ring test (PBRT). Além dos testes, foram aplicados dois questionários de qualidade de vida: Hospital Saint George na doença respiratória (SGRQ) e o Short Form 36 (SF-36

Reference values for the six-minute pegboard and ring test in healthy adults in Brazil

“… 9 It is time-limited (six minutes), validated, and reproducible, not only for individuals with COPD 7 but also for healthy adults. 10 Various studies have used the 6PBRT as a way to evaluate individuals with COPD 11 , 12 or as a way to compare them with healthy individuals 7 ; however, to date, no 6PBRT reference values have been determined for healthy individuals in Brazil. Knowledge of reference values for a test in healthy individuals is very important, because it will enable quantification of arm impairment in subjects with a disease and comparison of results, as well as assessment of the results of therapeutic interventions, especially in rehabilitation programs.…”

Correlation of Exercise Capacity with Functional Disability in Patients with Osteoarthritis of Knee

“…6 minute peg board ring test mimics activities of daily living which require unsupported arm function. It is inexpensive and simple test which assesses both arm function and endurance [4][5][6]. Knee injury and osteoarthritis outcome score (KOOS) is a self-administered questionnaire which has 42 items and 5 separately scored subscales which assesses pain, symptoms like swelling and range of motion limitation, activities of daily living, sport and recreation Charitable hospital, Mumbai with diagnosed osteoarthritis were selected according to the inclusion and exclusion criteria.…”
