- PublicaciónAcceso abiertoReproducibilidad de las pruebas Arm Curl y Chair Stand para evaluar resistencia muscular en población adulta mayor(2012-07-06) Boneth Collantes, Milena del Carmen; Ariza García, Claudia Lucía; Angarita Fonseca, Adriana; Parra Patiño, Javier; Monsalve, Andrea; Gómez, ElianaObjective: to assess the test-retest reliability and level of agreement between measures of the 30 second (30-s) Arm Curl and 30-s Chair Stand test in a sample of older adults from Bucaramanga.Materials and methods: a study of evaluation of diagnostic technology was done. Both tests were administered by the same evaluator to 111 adults older than 59 year-old (70,4 ± 7,3), on two occasions, with an interval of time between measures of 4 to 8 days. In the analysis, test-retest reliability was determined using the Intraclass Correlation Coefficient ICC= 2,1 with their confidence interval 95% (CI 95%) respective. The agreement level was established by the Bland and Altman method. Results: the test-retest reproducibility of the 30-s Arm Curl test was very good ICC= 0,88 and to the Chair Stand test was good ICC= 0,78. The agreement was very good for both tests of muscle endurance. The CI 95% were between -3,8 and 3,2 stands to 30-s Chair Stand test and between -3,1 and 2,8 curls to 30-s Arm Curl test. Conclusion: the 30-s Arm Curl and 30-s Chair Stand test have good reliability and agreement to assess muscle endurance in older adults functionally independent.
- PublicaciónAcceso abiertoReproducibilidad de una prueba para la evaluación funcional del balance dinámico y la agilidad del adulto mayor(2014-07) Angarita Fonseca, Adriana; Ariza García, Claudia Lucía; Boneth Collantes, Milena del Carmen; Parra Patiño, Javier; Rojas Santisteban, Rosa Nathaly; Angarita Carrascal, Yurley TatianaIntroducción: la prueba 8 foot up & go evalúa el balance dinámico y la agilidad del adulto mayor. Aunque se ha evaluado su reproducibilidad en población norteamericana, se desconoce si funciona de manera similar en una población diferente como la colombiana. Objetivo: evaluar la reproducibilidad prueba-reprueba y el nivel de acuerdo de la prueba 8 foot up & go para la evaluación funcional del balance dinámico y la agilidad en una muestra de adultos mayores de Bucaramanga. Materiales y métodos: se llevó a cabo un estudio de evaluación de pruebas diagnósticas en 114 adultos mayores. Se evaluó la reproducibilidad prueba-reprueba mediante el coeficiente de correlación intraclase (CCI [2,1]) con sus respectivos intervalos de confianza del 95% (IC95%). El nivel de acuerdo se estableció mediante el método de Bland y Altman. Resultados: la reproducibilidad prueba-reprueba fue muy buena (CCI: 0,98; IC95%: 0,98-0,99); se encontró buen nivel de acuerdo para las mujeres (promedio de las diferencias [PD] = 0,04 segundos y límites de acuerdo [LA]: -1,27; 1,36 segundos) y los individuos institucionalizados (PD = 0,04 segundos [LA]: -3,18; 3,27 segundos). Conclusión: la prueba 8 foot up & go tiene muy buena reproducibilidad y buen nivel de acuerdo en población adulta mayor local colombiana.
- PublicaciónAcceso abiertoReproducibilidad del cuestionario para determinar dolor lumbar inespecífico y sus características en escolares de 7 a 12 años(2013) Angarita Fonseca, Adriana; Ariza García, Claudia Lucía; Villamizar García, María-ConstanzaObjective: To assess the test-retest reliability of a questionnaire to determine nonspecific low back pain (NLBP) and its characteristics in schoolchildren aged 7 to 12 years. Metodology: An evaluation of diagnostic technologies was done in 84 schoolchildren (9.2 ± 1.6 years), 50 % girls, selected for convenience. The questionnaire was administered by individual interview, twice, with an interval of 2 to 4 days. We calculated the Intraclass Correlation Coefficient (CCI 2.1) to quantitative variables and Cohen´s and Weighted Kappa Index to qualitative variables with their respective confidence intervals at 95 % (CI95 %). Results: The prevalence was 20.2 % and 17.9 % in the first and second evaluation, respectively. The reliability of the questions that determine prevalence of NLBP was very good (k = 0.85, 95 % CI 0.69 - 1.00, n = 84); The number of days with NLBP in the last month got a fair reliability (CCI = 0.36; 95 % CI -0.009-0.70), while the duration asked by four categories of response was very good (k = 1.00; IC95 % 1.00-1.00), the intensity assessed by Wong-Baker F aces Pain Rating Scale was very good (ICC = 0.82, 95 % CI 0.54 - 0.93). In relation to consult a professional for back pain, Kappa indices ranged from k = 0.46 and k = 1.0. In the second evaluation, the children showed shorter duration of pain (3.9 days) and lower intensity (2.0). Discussion: The importance of reliability evaluation of the questionnaire to determine DLI and its characteristics is that there can be a valid measure unless the measure has some degree of reliability. The questionnaire to determine NLBP and their characteristics in schoolchildren aged 7 to 12 years is sufficiently reproducible for use in population studies.
