Introduction Maintaining human balance is a complex task, which is important because this function is an essential prerequisite for developing other capacities and for the daily life of human beings. Balance refers specifically to that situation in which the body adopts a determined position in relation to space with the head up, the face looking forward and the body erect for the purpose of positioning the head high. This standing position is called the orthostatic or erect position. In comparing the results between eyes open and eyes closed, with exception of the bipedal oscillations, all the cases presented values significantly greater with the eyes closed. In relation to the comportment of the oscillations, the bipedal ones presented greater values in the y axis oscillations and the monopedal oscillation values were higher in the x axis. Methods The methodology utilized was the collection of data by means of an electronic baropedometer and 30 subjects participated in the study (aged 40.47 ± 10.66 years). Data collection used an Electronic Baropedometer composed of a modular platform of Physical Support Italy. The data for analysis consisted of the anterior-posterior (y axis) and lateral (x axis) oscillations. The oscillations of the pressure center on the surface (in cm²). For each of the mentioned situations, the subjects were barefoot and they first did the test with their eyes open; afterwards subjects performed the same task with their eyes closed. In all cases the apparatus was calibrated to allow 5 seconds for executing the proceeding. Statistic treatment the software Statistica version 5.0 was used for statistical analysis. The coefficient of correlation of Pearson was used for functions of correlation; to verify significant differences Results / Discussion Statistical treatment with the t-Test was applied for studying comparisons between the oscillations in all manifestations. In the bipedal oscillation measure, no significant difference was observed when this was recorded with the eyes open compared to keeping the eyes closed. Great anterior-posterior oscillation was found both with the eyes open and eyes closed test.
