Influência da convergência proximal binocular na potência absoluta da banda alfa do eletroencefalograma em adultos jovens

Abstract

Introduction: The vergences are binocular movements that occur from a change in the angle of the visual axes, with them it is possible to move the eye reaching the fusion of the two monocular images and the perception with great precision and accuracy of the objects. In this context, the objective was to investigate the proximal binocular convergence in young individuals from 18 to 24 years of age, using as a measure the near-convergence point ruler and its relation with cortical activity through Quantitative Electroenphalography (EEGq). Twenty individuals from both genders, healthy, students from the Federal University of Piauí (UFPI) were recruited with mean age ± standard deviation [SD] = 20.6 ± 2.3 years (age range from 18 to 24 years), composed according to the sample calculation for infinite population, with error less than or equal to 0.05. The results of this study demonstrated that the oculomotor exercises performed with the PPC rule favor the improvement of HF. Regarding the CISS-vp questionnaire, there was improvement of the symptoms reported by the volunteers, reaffirming their application as a useful resource to the evolutionary monitoring of the patients. Regarding the EEG, there was a predominance of absolute alpha band power in the occipital cortex, thus, this result shows a greater demand of the alpha band oscillations for planning and attention, reinforcing the use of HF therapy based on the stimulation of CP using the PPC measurement ruler for the benefit of individuals.
