RESUMO
Introducción: La rehabilitación física puede verse beneficiada con el uso de dispositivos, los cuales en su mayoría suelen ser patentados. La oficina de patentes y marcas de los Estados Unidos (USPTO) es una de las oficinas de patentes y marcas más grandes y reconocidas. Resulta de interés evaluar las características y la evolución de las patentes para la rehabilitación física; sin embargo, existen pocos estudios al respecto. Objetivo: Identificar las características de las patentes de dispositivos de rehabilitación física de extremidades, registradas en la oficina de patentes y marcas de los Estados Unidos. Material y métodos: Estudio descriptivo transversal. Se realizó una búsqueda en UPSTO usando una lista de palabras clave relacionadas con la rehabilitación. Se eligieron 10 grupos de patentes relacionados con la rehabilitación. Las variables estudiadas fueron: número de la patente, fecha de publicación, país, titular, área de la patente, extremidades para las cuales es útil la patente y portabilidad. Se realizó un análisis descriptivo usando STATA v.14. Resultados: Se analizaron 1971 patentes, de las cuales 16,2 por ciento fueron incluidas en los grupos de rehabilitación y 83,8 por ciento en ejercicio físico. El 36,6 por ciento de todas las patentes fueron patentadas por un titular corporativo, el 29,9 por ciento fueron portables, y el 46,3 por ciento tenían utilidad para ambas extremidades. Conclusiones: De las patentes encontradas las enfocadas para ejercicio físico fueron las predominantes. Existe una mayor cantidad de patentes útiles para ambas extremidades. Además, existe una tendencia ascendente en el tiempo, en el número de patentes del área de rehabilitación y de las invenciones portables(AU)
ABSTRACT Introduction: Physical rehabilitation can be benefitted from the use of devices, which are usually patented. The United States Patent and Trademark Office (USPTO) is one of the largest and most recognized patent and trademark offices. The characteristics and evolution of patents for physical rehabilitation is of great interest; however, there are few studies in this respect. Objective: To identify the characteristics of patents of physical rehabilitation devices for the physical rehabilitation of damaged limbs registered the United States Patent and Trademark Office. Material and methods: A cross-sectional descriptive study was conducted. A search was made at UPSTO using a list of keywords related to rehabilitation. Ten groups of patents related to rehabilitation were chosen. The variables studied were: patent number, publication date, country, holder, patent area, limbs for which the patent is useful, and portability. A descriptive analysis was performed by using STATA v.14. Results: A total of 1971 patents were analyzed, of which 16.2 percent were included in the rehabilitation groups and 83.8 percent in the physical exercise groups. The 36.6 percent of them were corporate-owned patents, 29.9 percent were portable, and 46.3 percent had usability which demonstrated to be useful for both extremities. Conclusions: Of the patents found, those focused on physical exercise were predominant. There is a greater number of useful patents for both extremities. In addition, there is an upward trend over time, the number of patents in the area of rehabilitation, and portable inventions(AU)

Background: Educational environment refers to the material resources and interpersonal relationships of an educational institution. Aim: To describe the educational environment of a Peruvian medical school and to explore a possible association between curricular years and the educational environment. Material and Methods: A cross-sectional study was conducted using the Dundee Ready Education Environment Measure (DREEM) to evaluate the educational environment of a Peruvian medical school. Data collection consisted in online surveys completed voluntarily by 1st through 6th year medical students between April and October 2015. Results: The questionnaire was completed by 828 of 2,421 (34.2%) students. The mean DREEM score was 117 ± 25.6 of a maximum of 200. A poorer perception of the educational environment was associated with later years in the curriculum, when analysis was adjusted for gender, age and academic status (p < 0.001). Conclusions: The educational environment of this medical school scored positively (> 100 points). However, it was evident that medical students in later curricular years had a more negative perception of the educational environment compared to those in earlier academic years.

RESUMEN El objetivo del estudio fue determinar las propiedades psicométricas del cuestionario Dundee Ready Education Environment Measure (DREEM) en estudiantes de una facultad de Medicina peruana. Los participantes fueron los alumnos de primero a sexto año, invitados a participar mediante una plataforma web. En el análisis se utilizó el coeficiente alfa de Cronbach para evaluar consistencia interna. Además, se realizó un análisis factorial confirmatorio para evaluar la validez de constructo de las subescalas del DREEM. Los índices de bondad de ajuste utilizados fueron: error cuadrático medio de aproximación (RMSEA), el índice de ajuste comparativo (CFI), índice Tucker-Lewis (TLI) y el residuo estandarizado cuadrático medio (SRMR). Los resultados mostraron que la dimensión Autopercepción Social tuvo un alfa de Cronbach menor a 0,70. Además, los índices de bondad no apoyaron la estructura de cinco dimensiones del DREEM. Como conclusión, el cuestionario DREEM no tuvo un desempeño óptimo en esta muestra peruana.
ABSTRACT The objective of the study was to determine the psychometric properties of the Dundee Ready Education Environment Measure (DREEM) questionnaire in students of a Peruvian medical school. Participants were first-to-sixth-year students, invited to participate through a web platform. In the analysis the alpha coefficient of Cronbach was used to evaluate internal consistency. In addition, a confirmatory factorial analysis was performed to evaluate the construct validity of the subscales of the DREEM. The adjustment quality indexes used were: Root Mean Square Error Approximation (RMSEA), the Index of Benchmarking (CFI), Tucker-Lewis Index (TLI), and the Standardized Root Mean Residual (SRMR). The results showed that the social self-perception dimension had an alpha of Cronbach of less than 0.70. In addition, the quality indices did not support the five-dimensional structure of the DREEM. In conclusion, the DREEM questionnaire did not perform optimally in this Peruvian sample.
