Protocolo para posturografia estática com provas dinâmicas em indivíduos sem queixas vestibulares utilizando o sistema Horus

Introdução: O controle postural é mantido por meio da interação sinérgica entre sistemas somatossensorial, visual, vestibular e neuromusculoesquelético. Essa interação mantém o Centro de Gravidade (CG) dentro da Base de Suporte (BS) e do Limite de Estabilidade (LE), além de proporcionar respostas rápidas quando há perturbações externas. O controle postural pode ser avaliado por meio da posturografia, utilizando uma plataforma de força computadorizada ao qual o paciente é submetido a provas que proporcionam condições sensoriais diferentes, e promove estímulo do reflexo oculomotor optocinético, e é relevante para diagnóstico dos parâmetros que induzem a instabilidade, em várias condições clínicas, que inclui também a percepção de tontura pelo paciente e queixas de desequilíbrio corporal. Objetivo: trazer o método de avaliação da posturografia computadorizada Horus® em pacientes com disfunções no equilíbrio corporal de base vestibular. Metodologia: A plataforma de força computadorizada Horus®, é um sistema destinado ao diagnóstico do equilíbrio corporal na posição ereta, é composto por 15 provas diferentes, com variação de estímulo visual, posição da cabeça, posição corporal e utilização almofada de espuma para supressão parcial do equilíbrio corporal. As provas de 01 a 08 demonstram sigla e descrição fixas, em consequência dos requisitos da análise sensorial, e as provas de 09 a 15 podem ser modificadas pelo examinador. Conclusão: Trata-se de uma ferramenta importante, pois nos permite ter acesso a dados quantitativos da avaliação do equilíbrio corporal, e a partir destes resultados podemos direcionar intervenções de fisioterapêuticas com objetivo de traçar estratégias de coordenação motora e controle postural.

“…All tests of the peripheral nervous system currently used in clinical practice are based on the measurement of oligosynaptic reflexes of the brain stem [2]. Stabilometry, based on the assessment of human balance, which allows to detect vestibulo-spinal disorders, is no exception [3]. Equilibrium is the ability to maintain the center of pressure of the body with minimal shaking [4], and its control is provided by a combination of central and peripheral nerve components, including spinal reflexes, supraspinal commands and integration of afferent and/or efferent signals of visual, vestibular and somato-sensor.…”

“…Stabilometry, also known as stabilography or posturography, is a test in which the force platform is used to objectively assess the balance and obtain a quantitative approximation of the oscillations of the human mass center by registering the pressure center on the platform [3,5]. There are static and dynamic stabilometry.…”

The aim of the research – assessment of vestibular function in children with acute purulent otitis media by computer static stabilometry compared with typically developed children of the same age. Materials and methods: 22 children with purulent otitis media aged 4 to 7 years and 30 practically healthy peers were examined by static stabilometry on the device “MPFI stabilograph 1” (Kharkiv, Ukraine). Indicators of variation and shape of the pressure center distribution, spectral-correlation indicators of stabilograms, as well as integral indicators of stability (length, velocity and angle of postural oscillations) were taken into account and the equilibrium functions of the two sensory states (open and closed eyes) are calculated in the StabiliS software. Results: purulent otitis media causes posterior displacement of the absolute coordinates of the pressure center. In the state with closed eyes, children with purulent otitis differ from their healthy coevals by 14 of 24 stabilometric parameters, including stabilogram length, speed, angle and amplitude of oscillations, giving way to them in the stability of equilibrium. Children with purulent otitis media are more sensitive to the visual canal of postural control than their coevals. Involvement of visual afferents in postural control significantly improves balance maintenance in children with purulent otitis by reducing deviations of postural oscillations, which is reflected in the probable changes of 9 out of 24 stabilometric parameters compared to control. Conclusions: In preschool age, purulent otitis media leads to latent vestibular dysfunction, which is manifested by a violation of the stability of the vertical posture in a state with closed eyes and is compensated by visual-vestibulo-proprioceptive integration in the process of postural control.

The aim of the study is to assess the vestibular function of children with acute purulent otitis media by computer static stabilometry compared with typically developed peers. Materials and methods. In the course of the study 52 children aged 4 to 7 were examined by static stabilometry on the device «MPFI Stabilograph 1» (Kharkiv, Ukraine). 22 of them were diagnosed with purulent otitis media and their 30 peers were found to be practically healthy. Indicators of variations and forms of pressure center distribution, spectral-correlation indicators of stabilograms, as well as integral indicators of stability (length, velocity and angle of postural oscillations) and quality of equilibrium function in two sensory states (open and closed eyes) calculated in StabiliS software were taken into account. Results. Purulent otitis media causes posterior displacement of absolute coordinates of the pressure center. In the state with closed eyes, children with purulent otitis differ from their healthy peers in 14 of 24 stabilometric parameters, including stabilogram length, speed, angle and amplitude of oscillations, inferior to them in the balance. Children with purulent otitis media are more sensitive to the visual canal of postural control than their peers. Involvement of visual afferents in postural control significantly improves balance in children with purulent otitis by reducing deviations, postural fluctuations, which is reflected in the probable changes of 9 out of 24 stabilometric parameters compared to control. Conclusion. In preschool age, purulent otitis media leads to latent vestibular dysfunction, which is manifested by a violation of the stability of the vertical posture with the closed eyes and is compensated by visual-vestibular-proprioceptive integration in postural control.
