RESUMO
Resumen: Introducción: El pie caído es una condición que suele manejarse con ortesis cortas, normalmente fabricadas en polipropileno. Se ha descrito también su tratamiento con ortesis de silicón, poco estudiadas pero que parecen mejorar el patrón cinemático de la marcha y, dada su comodidad, ser más aceptadas por los pacientes. Nuestro estudio describe cuáles son las características cinemáticas de la marcha y la satisfacción referida por los pacientes al usar una ortesis tobillo pie de silicón y compara dicho patrón con el no uso de la ortesis en casos con pie caído. Material y métodos: Estudio seudoexperimental descriptivo en pacientes con pie caído desde el año 2010 al 2012, en el que se evaluaron las variables cinemáticas del patrón de marcha a partir de laboratorios de marcha y además de la satisfacción de los sujetos con las ortesis de silicón y con el no uso de las mismas. Resultados: Cinco casos con pie caído fueron objeto del estudio. El análisis de marcha de los pacientes que usaron la ortesis constató una mejora de la posición del tobillo en el contacto inicial, en la velocidad promedio de marcha y en la longitud del paso, así como un aumento de la cadencia. Sin embargo, en términos de comodidad en comparación con el no uso de la ortesis, el resultado fue exiguo. Conclusiones: Las ortesis tobillo pie de silicón mejoran la posición del tobillo en el contacto inicial, así como los parámetros temporoespaciales de la marcha.
Abstract: Introduction: The Drop foot is a condition that is usually handled with short orthosis, usually made of polypropylene. It has also been described as being treated with silicon orthosis, little studied but which seem to improve the kinematic pattern of gait and, given its comfort, be more accepted by patients. Our study describes the kinematic characteristics of gait and patient satisfaction when using a silicon foot ankle orthosis, and compares this pattern to the non-use of the orthosis, in patients with a drop foot. Material and methods: Pseudo-experimental descriptive study in patients with dropped feet from 2010 to 2012, in which the kinematic variables of the gait pattern were evaluated from gait laboratories and in addition to the satisfaction of subjects with silicon orthosis and non-use of them. Results: Five patients with a drop foot were the subject of the study. Gait analysis of patients using the orthosis found an improvement in ankle position at initial contact, average walking speed and step length, as well as increased cadence. However, in terms of comfort compared to the non-use of the orthosis, the result was meager. Conclusions: Silicon foot ankle orthosis improve the position of the ankle in the initial contact, as well as the temporo-spatial parameters of the gait.

INTRODUCTION: Stroke is currently the main cause of permanent disability in adults. The impairments are a combination of sensory, motor, cognitive and emotional changes that result in restrictions on the ability to perform basic activities of daily living (BADL). Postural control is affected and causes problems with static and dynamic balance, thus increasing the risk of falls and secondary injuries. The purpose of this review was to compile the literature to date, and assess the impact of ankle-foot orthosis (AFO) on postural control and gait in individuals who have suffered a stroke. DEVELOPMENT: The review included randomised and controlled trials that examined the effects of AFO in stroke patients between 18 and 80 years old, with acute or chronic evolution. No search limits on the date of the studies were included, and the search lasted until April 2011. The following databases were used: Pubmed, Trip Database, Cochrane library, Embase, ISI Web Knowledge, CINHAL and PEDro. Intervention succeeded in improving some gait parameters, such as speed and cadence. However it is not clear if there was improvement in the symmetry, postural sway or balance. CONCLUSIONS: Because of the limitations of this systematic review, due to the clinical diversity of the studies and the methodological limitations, 0these results should be considered with caution.
