Relación entre la postura sedente y la utilización de mobiliario recomendado por la norma ISO 5970 en una población escolar

Abstract

Introduction: The objectives of this study are to analyze and assess the dimensions of furniture school (chairs and tables) used at school by students of different ages and compare them with those recommended by the ISO standard, as well as describing the influence on the seated position that has the use or not of a recommended furniture. Material and method: A population of Salamanca schoolchildren is chosen at random. The sitting posture of each individual during the period of attention to the teacher is observed, while a tab that includes the different parameters that describe the sitting posture. The magnitudes of the different models of chairs and tables are measured, collecting the data in tables. In addition, the sizes of each of the individuals are measured. Results: The individuals studied were 68 belonging to the 3 ', 4', 5 'and 6' courses of primary education. Of them, 51, S% were girls and the rest children. The average age was 10.38 years ± 1,244 years and the average size of 144.74 cm. We have found five different models of chairs and two of tables, whose dimensions do not conform to those reflected in the ISO standard. 44.11% of the individuals used chairs recommended for their height, while only 14.7% did so with the tables. There was no homogeneity between the courses. Individuals who did not use recommended for high chairs tended to keep a previous sitting posture (50%), adopt a flexed position (68.4%) column not rest your feet on the ground (55.3%) and do not use the backup (50%). However, the results were not statistically significant.
