Validity and Reliability of an Inertial Device for Measuring Dynamic Weight-Bearing Ankle Dorsiflexion

A decrease in ankle dorsiflexion causes changes in biomechanics, and different instruments have been used for ankle dorsiflexion testing under static conditions. Consequently, the industry of inertial sensors has developed easy-to-use devices, which measure dynamic ankle dorsiflexion and provide additional parameters such as velocity, acceleration, or movement deviation. Therefore, the aims of this study were to analyze the concurrent validity and test-retest reliability of an inertial device for measuring dynamic weight-bearing ankle dorsiflexion. Sixteen participants were tested using an inertial device (WIMU) and a digital inclinometer. Ankle dorsiflexion from left and right ankle repetitions was used for validity analysis, whereas test-retest reliability was analyzed by comparing measurements from the first and second days. The standard error of the measurement (SEM) between the instruments was very low for both ankle measurements (SEM 0.05) even though a significant systematic bias (~1.77°) was found for the right ankle (d = 0.79). R2 was very close to 1 in the left and right ankles (R2 = 0.85–0.89) as well as the intraclass correlation coefficient (ICC > 0.95). Test-retest reliability analysis showed that systematic bias was below 1° for both instruments, even though a systematic bias (~1.50°) with small effect size was found in the right ankle (d = 0.49) with WIMU. The ICC was very close to 1 and the coefficient of variation (CV) was lower than 4% in both instruments. Thus, WIMU is a valid and reliable inertial device for measuring dynamic weight-bearing ankle dorsiflexion

La eficacia de los programas de entrenamiento a padres en las publicaciones recientes

Se expone una revisión sistemática de los estudios empíricos sobre los programas de entrenamiento a padres realizados en los últimos 16 años. A partir de un filtraje en las principales bases de datos, se analizaron 48 artículos que incluían estudios empíricos, con diseños y datos de resultados, de programas de entrenamietno a padres en distintos tipos de problemas. Este tipo de programas muestra eficacia en la redución de los problemas de conducta, el maltrato infantil, problemas de agresividad, y bulling, trastornos de desarrollo infantil, pero también también en la educación afectivo-sexual, la prevención de problemas de adicciones y alimenarios en adolescentes. Teniendo en cuenta los criterios APA sobre tratamientos con base empírica, se clasificaron esos programas según su calidad y validez clínica.Universidad de Málaga.

Unidades de empreendimento sob um estudo de eficiência relativa

This article presents a comparative analysis of the relative efficiency of a group of Entrepreneurship Units (UE ) located in Bogota , using Data Envelopment Analysis ( DEA ) . Based on the information obtained from the EU studied inputs and outputs were defined, the different sub-models were generated, the Efficient Frontier for each one and the factors that determined that condition were analyzed. This study concludes by raising the possibility of advancing similar studies in organizations dedicated to promote and support entrepreneurship in other countries in order to continue to build knowledge around this subject.Este artículo presenta un análisis comparativo de la eficiencia relativa de un grupo de Unidades de Emprendimiento (UE) ubicadas en la ciudad de Bogotá, utilizando Data Envelopment Analysis (DEA). Con base en la información obtenida de las UE estudiadas se definieron las entradas y salidas, se generaron los diferentes submodelos, la Frontera Eficiente para cada uno y se analizaron los factores que determinaron esa condición. El presente estudio termina planteando la posibilidad de adelantar estudios similares en organizaciones dedicadas a promover y apoyar el emprendimiento en otros países, con el fin de continuar construyendo conocimiento alrededor de esta temática.Este artigo apresenta uma análise comparativa da eficiência relativa de um grupo de Unidades de Empreendimento (UE) localizadas na cidade de Bogotá, utilizando Date Envelopment Analysis (DEA).
