ABSTRACT
Objetivo: revisar críticamente la literatura sobre la validez y fiabilidad del test de descenso del navicular como herramienta clínica de evaluación de la pronación del pie. Método: Se ha realizado una revisión de la literatura existente sobre el tema en las principales bases de datos de ciencias de la salud. Para realizar la búsqueda se emplearon los terminos MeSH (navicular drop, pronation, foot) interconectados con los respectivos conectores booleanos. Resultados: Se seleccionaron finalmente un total de 38 artículos científicos en castellano e inglés sobre la fiabilidad y validez interna del test. Conclusiones: El test de descenso del navicular es una herramienta ampliamente utilizada en estudios de investigación. Sin embargo, con la evidencia disponible, podemos afirmar que la fiabilidad y validez interna del test es cuanto menos cuestionable para que este pueda ser usado con fines de investigación. (AU)

PURPOSE: The study was conducted to investigate the onset time and safety profile of four different local anesthetic solutions. DESIGN: Randomized controlled clinical trial study. METHODS: One hundred twelve healthy volunteers were assigned to receive digital block on their second toe. Individuals were randomly assigned to one of the following groups: lidocaine 2%, lidocaine 2% with epinephrine, bupivacaine 0.5%, or bupivacaine 0.5% with epinephrine. Onset time was measured until detecting the absence of pinprick sensation. Oxygen saturation was measured in the infiltrated toe up to 60 minutes. FINDINGS: The subjects in the groups of anesthetics with epinephrine had a significantly lower mean onset time. There were no significant differences regarding oxygen saturation between the groups and no adverse effects were recorded. CONCLUSIONS: The use of anesthetics with epinephrine can be an effective form of local anesthetic for digital blocks when a rapid onset of action, prolonged duration of anesthesia, and vasoconstrictive action are required.
