Validação de uma bateria de testes motores para avaliação da capacidade funcional de adultos com síndrome de Down

Abstract

Introduction: Adults with Down syndrome (DS) have reduced functional capacity (FC) and little research has evaluated FC in adult individuals with DS and an even smaller number has evaluated the validity and reliability of tests used for this purpose. Objective: The objective of this study is to validate a battery of motor tests, to verify the reliability of the tests for the evaluation of FC, to verify the agreement between the original and adapted tests for the battery and to describe the relationship of sociodemographic, biological and behavioral factors and the performance of FC in adults with DS. Materials and methods: The battery includes the 10 meter walk test (TC10m), Timed up and go (TUG), one-leg support tests (TAU), sit and stand test (TSLC), stand up test (TLS), test dressing shirt ( TVC) and the breakfast test (TCM), in addition to body composition variables (body mass and height). The content validity was verified by the appreciation of six judges specialized in physical education and disability. The test-retest method was used with an interval of seven days between validations. The reliability of intra- and inter-evaluators was verified. As statistical resources, the content validity index (CVI) was used to check the content validity, the intraclass correlation index (ICC) to check the reliability, in addition to the analysis of the Bland-Altman dispersion graph to check differences between original and adapted tests. A T-test was also used to verify differences in means. To verify the relationship of FC with the variables of age, sex, family income, literacy, body mass index (BMI), presence of diseases, physical activity (PA) and sedentary time (TS). Descriptive statistics and analysis of variance (Anova OneWey), T-test independent, Mann-Whitney and Kruskall Wallis resources were used to verify differences in means. Results: The study included 41 people with DS, aged between 18 and 59 years (mean 30.41, SD + -10.41). Average body mass of 68.57 kg (SD + -17.18) and average height of 1.52 (SD + -0.09). A 0.95 CVI was observed for the test battery. In relation to the intra-rater ICC, all values above 0.83 were found and inter-rater values above 0.75, with the exception of the TVC (ICC = 0). The FC score (sCF) is significantly related to being literate, being physically active and spending less than 6 hours in sedentary activities. Conclusion: The battery of tests presents content validity and reliability of your tests. The encouragement of literacy, as well as the practice of PA and reduction of time in sedentary activities should be encouraged as they help to improve FC and, consequently, in the autonomy and independence of people with DS.
