Validação do 6 minute pegboard and ring test (6pbrt) para indivíduos com cardiomiopatia

Abstract

Introduction: Cardiomyopathy is defined as a disease in the myocardium associated with the dysfunction of this muscle. Objective: To validate the 6 Minutes Pegboard and Ring Test (6PBRT) for cardiomyopathic individuals, correlating with palmar grip strength, quality of life and anthropometric variables. Methodology: Cross-sectional, descriptive and analytical epidemiological study with a quantitative approach with cardiomyopathic patients, from July to November, 2017. Consecutive, non-probabilistic, convenience sample. Peripheral muscle strength test of the upper limbs was performed by the Jamar manual dynamometer and the 6PBRT, to evaluate the functional capacity. The Minnesota Living with Heart Failure Questionnaire (MLHFQ) questionnaire was applied. For the comparison between the variables we used the T test and for correlations we applied the Pearson correlation coefficient. The level of significance considered was equal to or less than 5%. Results: Ten cardiomyopathic patients were evaluated, with a mean age of 66.1 years. The participants had a reduction of the palmar grip strength of 29.5% in the dominant hand and 24.8% in the non-dominant hand when compared to the predicted hand (p <0.000). In the MLHFQ we found an average of 17.9 points, indicating a good quality of life. The 6PBRT showed no correlation with most of the studied variables, only obtained a moderate negative correction with the age of the participants. Conclusion: It was not possible to statistically analyze the validity of 6PBRT for cardiomyopathic patients, due to the small sample size that did not allow an accurate analysis of the correlations. Individuals had decreased peripheral muscle strength, but good scores on the quality of life questionnaire.
