Analysis of Compliance with Time under Tension and Force during Strengthening Exercises with Elastic Bands
Quantifying training variables of a physical exercise modality is essential for an appropriate dosage. In training with elastic bands, time under tension (TUT) and force represent the duration and intensity of this force-training modality. The aims of this study were to evaluate the degree of compliance to TUT prescription for three different scenarios of two exercises and the comparison of the force values obtained versus the estimate values. A total of 29 healthy volunteers were evaluated in a clinical environment under controlled conditions in 3 different scenarios (different velocities or ROMs) of both shoulder abduction and knee extension in 2 sets of 10 repetitions per scenario within…

Patterns and Predictors of Recovery from Poor Health Status Measured with the Chronic Obstructive Pulmonary Disease (COPD) Assessment Test in Patients with Stable COPD: A Longitudinal Study
Recent recommendations for chronic obstructive pulmonary disease (COPD) suggest that evaluation and management should focus on patient health status. Despite the frequency of poor health status and its negative impact on patients with COPD, little is known about how poor or non-poor health status persists and/or remits over time or what factors might predict recovery from a poor health status. The aim was to determine the likelihood of transitioning between poor and non-poor health status in patients with stable COPD followed for 2 years and to investigate factors that might predict recovery from poor health status. We prospectively included 137 patients with stable COPD (mean age, 66.9 yea…
An Optoelectronic System for Measuring the Range of Motion in Healthy Volunteers: A Cross-Sectional Study.
Background and Objectives: Within the clinical evaluation of multiple pathologies of the lower limb, the measurement of range of motion (ROM) of its joints is fundamental. To this end, there are various tools, from the goniometer as a reference to more recent devices such as inclinometry-based applications, photo capture applications, or motion capture systems. This study aimed to assess the validity, intra-rater, and inter-rater reliability of the VeloFlex system (VS), which is a new camera-based tool designed for tracking joint trajectories and measuring joint ROM. Materials and Methods: Thirty-five healthy volunteers (16 females
Estructura y propiedades métricas de un cuestionario para medir discapacidad en las actividades de movilidad en pacientes con enfermedad pulmonar obstructiva crónica (cuestionario DIAMO-EPOC)
Resumen Objetivo El objetivo del estudio fue adaptar un cuestionario de discapacidad en actividades de movilidad (DIAMO-EPOC) incorporando escalas basadas en el marco conceptual de la Clasificacion Internacional del Funcionamiento, Discapacidad y Salud, y examinar su estructura, fiabilidad y validez en una cohorte de pacientes con EPOC. Metodos Un total de 137 pacientes con EPOC estable fueron reclutados. Se disenaron dos escalas de cuatro items cada una y se verifico su estructura mediante analisis factorial y de multirrasgo. Adicionalmente, se calcularon los indices de fiabilidad (consistencia interna y test-retest). La validez de constructo se analizo mediante grupos conocidos y la conve…
Validity, Reliability, and Sensitivity to Change of DiCI for the Strength Measurement of Knee and Hip Muscles
Many professionals use the handheld dynamometers (HHDs) to assess isometric strength. This study aimed to evaluate the validity, reliability, and sensitivity to change of a DiCI (a new HHD) for the...
