Validity and reliability of new the Basic Functional Assessment protocol (BFA)
The global evaluation of motion patterns can examine the synchrony of neuromuscular control, range of motion, strength, resistance, balance and coordination needed to complete the movement. Visual assessments are commonly used to detect risk factors. However, it is essential to define standardized field-based tests that can evaluate with accuracy. The aims of the study were to design a protocol to evaluate fundamental motor patterns (FMP), and to analyze the validity and reliability of an instrument created to provide information about the quality of movement in FMP. Five tasks were selected: Overhead Squat (OHS); Hurdle Step (HS); Forward Step Down (FSD); Shoulder Mobility (SM); Active Stretching Leg Raise (ASLR). A list of variables was created for the evaluation of each task. Ten qualified judges assessed the validity of the instrument, while six external observers performed inter-intra reliability. The results show that the instrument is valid according to the experts’ opinion; however, the reliability shows values below those established. Thus, the instrument was considered unreliable, so it is recommended to repeat the reliability process by performing more training sessions for the external observers. The present study creates the basic functional assessment (BFA), a new protocol which comprises five tasks and an instrument to evaluate FMP.
A Meta-Analysis of the Reliability of Four Field-Based Trunk Extension Endurance Tests
This meta-analysis aimed to estimate the inter- and intra-tester reliability of endurance measures obtained through trunk extension field-based tests and to explore the influence of the moderators on the reliability estimates. The reliability induction rate of trunk extension endurance measures was also calculated. A systematic search was conducted using various databases, and subsequently 28 studies were selected that reported intraclass correlation coefficients for trunk extension endurance measures. Separate meta-analyses were conducted using a random-effects model. When possible, analyses of potential moderator variables were carried out. The inter-tester average reliability of the endurance measure obtained from the Biering-Sorensen test was intraclass correlation coefficient (ICC)= 0.94. The intra-session reliability estimates of the endurance measures recorded using the Biering-Sorensen test, the prone isometric chest raise test, and the prone double straight-leg test were ICC= 0.88, 0.90, and 0.86, respectively. The inter-session average reliability of the endurance measures from the Biering-Sorensen test, the prone isometric chest raise test, and the dynamic extensor endurance test were ICC= 0.88, 0.95, and 0.99, respectively. However, due to the limited evidence available, the reliability estimates of the measures obtained through the prone isometric chest raise, prone double straight-leg, and dynamic extensor endurance tests should be considered with a degree of caution. Position control instruments, tools, and familiarization session demonstrated a statistical association with the inter-session reliability of the Biering-Sorensen test. The reliability induction rate was 72.8%. Only the trunk extension endurance measure obtained through the Biering-Sorensen test presented sufficient scientific evidence in terms of reliability to justify its use for research and practical purposes.

Efecto del nivel de experiencia clínica del examinador sobre la validez de criterio y fiabilidad inter-sesión de cinco medidas del rango de movimiento de la flexión dorsal del tobillo
El objetivo de este estudio fue analizar el efecto que el diferente grado de experiencia del examinador tiene sobre la validez de criterio y fiabilidad inter-sesión de las medidas de rango de movimiento de la flexión dorsal del tobillo (ROMFDT) obtenidas en las pruebas: flexión dorsal del tobillo pasiva en decúbito prono y rodilla flexionada (FDPAS), zancada con inclinómetro (FDZAN-INC) y cinta métrica (FDZAN-MET), zancada modificada con taburete (FDZAN-TAB) y zancada modificada con cajón (FDZAN-CAJ). Un total de 17 deportistas recreativos completaron este estudio. Cada participante fue evaluado por dos examinadores con distinto nivel de experiencia (experto y novel) del ROMFDT empleando 5 pruebas exploratorias diferentes en dos sesiones distintas. Los resultados muestran bajos valores de validez para el examinador novel en todas las pruebas de valoración del ROMFDT excepto en la prueba FDZAN-INC (error típico de la estimación estandarizado = 0,5 [pequeño]; Pearson = 0,85 [moderado]; kappa = 0,74 [buena]). El examinador experto presentó niveles altos de fiabilidad inter-sesión en las pruebas FDZAN-INC, FDZAN-MET y FDZAN-CAJ y valores aceptables en las pruebas FDPAS y FDZAN-TAB. El examinador novel obtuvo valores aceptables de fiabilidad en toda las pruebas de valoración excepto en la prueba FDPAS, que fueron considerados como no aceptables. Por lo tanto, se recomienda que tanto los examinadores expertos como noveles utilicen la prueba FDZAN-INC para: (a) identificar a personas con restringida o normal movilidad de la flexión dorsal del tobillo; y (b) monitorizar la eficacia de los programas de intervención aplicados en caso de ser necesarios.
