Traducción al portugués brasileño, adaptación transcultural, fiabilidad y validación de la Functional Ambulation Classification para la categorización de deambulación postictus en un entorno clínico / Translation into Brazilian Portuguese, cross-cultural adaptation, reliability and validation of the Functional Ambulation Classification for the categorization of ambulation following a stroke in a clinical setting

INTRODUCCIÓN: La Functional Ambulation Classification (FAC) es la única escala que clasifica la marcha de individuos con esclerosis múltiple e ictus en categorías de deambulación. Sin embargo, la FAC sólo está disponible en la versión en inglés y los estudios realizados en Brasil la han utilizado sin una traducción y análisis adecuados de propiedades psicométricas. OBJETIVO: Traducir y adaptar culturalmente la FAC para el portugués brasileño y probar su fiabilidad y validez concurrente en individuos afectados por ictus. PACIENTES Y MÉTODOS: La traducción y la adaptación transcultural implicaron seis pasos. La fiabilidad interevaluador se probó con cinco fisioterapeutas que vieron vídeos de la marcha de las personas afectadas por ictus y, después de un intervalo mínimo de una semana, los vieron por segunda vez para determinar la fiabilidad intraevaluador. La validez concurrente se determinó correlacionando la FAC con el resultado de la prueba de marcha de 10 metros (PM 10m). RESULTADOS: La fiabilidad intraevaluador varió entre un valor kappa de 0,68-0,95 (p = 0,001), y la fiabilidad interevaluador, un valor kappa de 0,517-0,794 (p = 0,001). La correlación entre la FAC y la PM 10 m fue rs = 0,771 (p = 0,001). CONCLUSIÓN: La traducción, la adaptación transcultural y el análisis de las propiedades psicométricas demostraron que la FAC es una medida clínica válida y fiable para clasificar la deambulación de los individuos brasileños afectados por ictus en un entorno clínico

INTRODUCTION. The Functional Ambulation Classification (FAC) is the only scale that classifies the gait of individuals with multiple sclerosis and stroke victims into ambulation categories. However, the FAC is only available in English and studies conducted in Brazil have used the FAC without an adequate translation and analysis of its measurement properties. AIM. To translate, cross-culturally adapt the FAC to Brazilian Portuguese, test its reliability and concurrent validity on stroke survivors. PATIENTS AND METHODS. The translation and cross-cultural adaptation involved six steps. Inter-observer reliability was tested with five physiotherapists who watched videos of the gait of the stroke survivors and watched a second time after at least one week for the determination of intra-observer reliability. Concurrent validity was determined by correlating the FAC with the result of the 10-meter Walk Test (10 mWT). RESULTS. Intra-observer reliability ranged from kappa 0.680 to 0.952 (p = 0.001) and inter-observer reliability ranged from kappa 0.517 to 0.794 (p = 0.001). The correlation between the FAC and 10mWT was rs = 0.771 (p = 0.001). CONCLUSION. The translation, cross-cultural adaptation and measurement properties demonstrated that the FAC is a valid, reliable clinical measure for the categorization of ambulation in the Brazilian population of stroke survivors in a clinical setting

Validación y reproducibilidad de la prueba Glittre de actividades de la vida diaria en personas con enfermedad de Parkinson / Validation and reproducibility of the Glittre activities of daily living test for individuals with Parkinsons disease

Objetivo: Investigar la validez y la reproducibilidad de la prueba Glittre de actividades de la vida diaria (AVD-Glittre) para personas con enfermedad de Parkinson. Sujetos y métodos: Se evaluó a 30 pacientes con enfermedad de Parkinson y 19 sujetos sanos (grupo de control). El grupo con enfermedad de Parkinson fue evaluado con la Unified Parkinson’s Disease Rating Scale (UPDRS) y sometido a la prueba AVD-Glittre, la prueba de marcha de seis minutos (6 MWT) y la prueba de marcha de 10 metros (10mWT). El grupo de control realizó la prueba AVD-Glittre. Para el análisis intraobservador se realizaron dos pruebas AVD-Glittre, y para el análisis interobservador, la prueba se repitió otro día con un segundo examinador. Resultados: La prueba AVD-Glittre se correlacionó significativamente con la sección II, la sección III y la puntuación total de la UPDRS. Se correlacionó inversamente con la 6MWT y positivamente con la 10mWT. El tiempo requerido para realizar la prueba AVD-Glittre fue más corto en la nueva prueba en el análisis intraobservador y en el análisis interobservador. La diferencia de medias entre la primera y la segunda pruebas, el error estándar de medición y el cambio mínimo detectable en minutos fueron 0,40, 0,08 y 0,24, respectivamente, para el análisis intraobservador, y 0,40, 0,22 y 0,62, respectivamente, para el análisis interobservador. Conclusión: La prueba AVD-Glittre es válida y reproducible para evaluar la capacidad funcional en personas con enfermedad de Parkinson

Aim: To investigate the validity and reproducibility of the Glittre Activities of Daily Living (Glittre-ADL) test for individuals with Parkinsons disease. Subjects and methods: Thirty individuals with Parkinson’s disease and 19 healthy individuals (control group) were evaluated. Parkinson’s disease group was evaluated by the Unified Parkinson’s Disease Rating Scale (UPDRS) and underwent the Glittre-ADL test, six-minute walk test (6MWT) and ten-meter walk test (10mWT). Control group performed the Glittre-ADL test. For the intraobserver analysis, two Glittre-ADL tests were performed. For the interobserver analysis, the Glittre-ADL test was repeated on a different day by a second examiner. Results: The Glittre-ADL test was significantly correlated with UPDRS Section II, Section III, and total score. The Glittre-ADL test was inversely correlated with the 6MWT and positively correlated with the 10mWT. The time required to perform the Glittre-ADL test was shorter on the retest in the intraobserver analysis and in the interobserver analysis. The mean difference between the first and second tests, the standard error of measurement and minimum detectable change in minutes were 0.40, 0.08 and 0.24, respectively, for intraobserver, and 0.40, 0.22 and 0.62, for interobserver. Conclusion: The Glittre-ADL test is valid and reproducible to evaluate functional capacity in individuals with Parkinsons disease

Validation and reliability of a modified sphygmomanometer for the assessment of handgrip strength in Parkinson's disease.

BACKGROUND: Handgrip strength is currently considered a predictor of overall muscle strength and functional capacity. Therefore, it is important to find reliable and affordable instruments for this analysis, such as the modified sphygmomanometer test (MST). OBJECTIVES: To assess the concurrent criterion validity of the MST, to compare the MST with the Jamar dynamometer, and to analyze the reproducibility (i.e. reliability and agreement) of the MST in individuals with Parkinson's disease (PD). METHOD: The authors recruited 50 subjects, 24 with PD (65.5 ± 6.2 years of age) and 26 healthy elderly subjects (63.4 ± 7.2 years of age). The handgrip strength was measured using the Jamar dynamometer and modified sphygmomanometer. The concurrent criterion validity was analyzed using Pearson's correlation coefficient and a simple linear regression test. The reproducibility of the MST was evaluated with the coefficient of intra-class correlation (ICC(2,1)), the standard error of measurement (SEM), the minimal detectable change (MDC), and the Bland-Altman plot. For all of the analyses, α ≤ 0.05 was considered a risk. RESULTS: There was a significant correlation of moderate magnitude (r ≥ 0.45) between the MST and the Jamar dynamometer. The MST had excellent reliability (ICC(2,1) ≥ 0.7). The SEM and the MDC were adequate; however, the Bland-Altman plot indicated an unsatisfactory interrater agreement. CONCLUSIONS: The MST exhibited adequate validity and excellent reliability and is, therefore, suitable for monitoring the handgrip strength in PD. However, if the goal is to compare the measurements between examiners, the authors recommend that the data be interpreted with caution.

The handgrip strength was measured using the Jamar dynamometer and modified sphygmomanometer. The concurrent criterion validity was analyzed using Pearson's correlation coefficient and a simple linear regression test. The reproducibility of the MST was evaluated with the coefficient of intra-class correlation (ICC2,1), the standard error of measurement (SEM), the minimal detectable change (MDC), and the Bland-Altman plot. For all of the analyses, α≤0.05 was considered a risk. RESULTS: There was a significant correlation of moderate magnitude (r≥0.45) between the MST and the Jamar dynamometer. The MST had excellent reliability (ICC2,1≥0.7). The SEM and the MDC were adequate; however, the Bland-Altman plot indicated an unsatisfactory interrater agreement. CONCLUSIONS: The MST exhibited adequate validity and excellent reliability and is, therefore, suitable for monitoring the handgrip strength in PD.

Comparison of quality-of-life instruments for assessing the participation after stroke based on the International Classification of Functioning, Disability and Health (ICF).

BACKGROUND: According to the International Classification of Functioning, Disability and Health (ICF), the participation component is considered to be the most complex component characterized in existing instruments that assess quality of life related to health (HRQoL). Questionnaires such as the Nottingham Health Profile (NHP) and the Stroke-Specific Quality of Life (SS-QOL) are currently used to evaluate the participation of individuals in life activities after stroke. However, because participation and HRQoL are different constructs, it is unclear whether these instruments are best suited to this evaluation. OBJECTIVE: To investigate whether the NHP and SS-QOL are suitable instruments for assessing the participation component of ICF. METHOD: A cross-sectional study was conducted in which a sample of 35 individuals completed the SS-QOL and NHP. The study correlated the total score on the questionnaires with the scores on items that evaluate the participation component of the ICF. Both analyses used the Spearman correlation coefficient (r). RESULTS: There was a statistically significant, positive and strong correlation between total score on the SS-QOL and NHP and the score on specific components related to participation (r=0.8, p=0.001 and r=0.9, p=0.001, respectively). CONCLUSIONS: Both the NHP and the SS-QOL show strong correlations between the total score and the score on items that assess the participation categories of the ICF. However, the SS-QOL questionnaire appeared to be the most complete for this assessment because it evaluates more distinct domains and contains the largest number of items related to participation.

CONTEXTUALIZAÇÃO: O componente de participação da Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF) foi apontado como o mais complexo de ser caracterizado a partir de instrumentos já existentes. Atualmente, indica-se o uso de questionários de qualidade de vida relacionada à saúde (QVRS) para avaliação da participação após acidente vascular encefálico (AVE), sendo indicado o Nottingham Health Profile (NHP) e o Stroke Specific Quality of Life (SS-QOL). No entanto, QVRS e participação são construtos distintos, assim, não está claro se esses instrumentos são os mais adequados para essa avaliação. OBJETIVO: Investigar se o NHP e SS-QOL são apropriados para avaliação do componente de participação da CIF. MÉTODO: Estudo transversal com amostra de 35 indivíduos nos quais foram aplicados o SS-QOL e o NHP com intuito de correlacionar o escore total dos questionários com o escore dos itens que avaliam os códigos do componente de participação da CIF utilizando o Coeficiente de Correlação Spearman (r). RESULTADOS: Houve correlação estatisticamente significante, positiva e de forte magnitude entre o escore total do SS-QOL e do NHP com os escores específicos do componente de participação, (r=0,8; p=0,001) e (r=0,9; p=0,001), respectivamente. CONCLUSÕES: Tanto o NHP quanto o SS-QOL apresentaram correlação forte entre o escore total e o escore dos itens que avaliam as categorias de participação da CIF. No entanto, o SS-QOL pareceu ser o questionário mais completo para essa avaliação por avaliar mais domínios distintos e apresentar o maior número de itens relacionados à participação. .
