“…Balance skills of the tested children and adolescents, both sexes, manifested im pro ve ment with the age. These results are in agreement with the data of the other authors (Rutkowska et al, 2015). Similar trend was observed for the eye-sighted general population (Slanchev P. et al 1992).…”

“…Some authors did not observe any statistical difference between the fitness score of children with low vision and those who are blind (Kozub & Oh, 2004, Lieberman et al, 2002. Recent results of Rutkowska et al (2015) indicated that the ability to maintain balance is associated with the degree of visual impairment and partially eye-sighted people demonstrate better results than the blind (Rutkowska et al, 2015). However, there are even research studies showing that totally blind pupils may maintain equilibrium better than legally blind subjects (Juodžbalienė & Muskus, 2006).…”

The importance of the visual abilities for the normal balance skills is well studied. However, it is not fully clarified how the severity of visual impairment of children and adolescents disturbs the balance and the impact of physical activity on this component of fitness. This study is aiming at establishing the importance of extracurricular physical activity on the balance abilities of school-aged children with visual disabilities considering their sex, age, and degree of impairment. Two hundred and nineteen children and adolescents with visual impairment, aged between 12 and 19 years, participated in this study. The participants were divided into groups according to the age (12-14 y., 15-17 y., and 18-19 y.), sex, visual impairment (with low vision and blind), and level of physical activity (with and without extracurricular sport participation). The balance skills were measured by the time in seconds for single-leg balancing. Ordinary statistic for describing variations was employed. The balance skills of visually impaired children increased with age. There were no significant differences (p<0.05) in the balance between the sexes in all age groups. Balance skills comparison of the children, having different degrees of visual impairment also registered similar results in both groups. The female and male children and adolescents from all age groups who participated in extracurricular sports scored better in the balance test (p<0.05). This study characterized the balance skills of children with different levels of visual disability across age in both sexes, and confirmed the positive effect of physical activity on this fitness component.

“…As informações captadas por esses sistemas são integradas no sistema nervoso central, de modo que ajustes sejam feitos para a manutenção da postura, seja em repouso ou movimento 13 . Assim, na ausência ou na presença precária de um importante componente, como é a visão, é possível que o equilíbrio esteja comprometido, ainda que estratégias compensatórias sejam desenvolvidas pelos demais sistemas 14,15 .…”

O objetivo do estudo foi descrever o controle postural na posição ereta semiestática de atletas com diferentes graus de deficiência visual e verificar se existem diferenças de acordo com a modalidade esportiva praticada. Participaram deste estudo seccional 22 atletas com perda total da visão (classificação funcional B1) e 17 com baixa visão (classificação funcional B2 e B3) das modalidades judô (n=17), goalball (n=12) e futebol de cinco (n=10). O controle postural foi investigado utilizando uma plataforma de força, sendo calculadas a área da elipse de 95% de intervalo de confiança (mm 2) e a velocidade média de deslocamento (mm/s). A tarefa postural foi realizada com os pés unidos e olhos fechados e vendados. Atletas com perda total da visão apresentaram menores valores para área de oscilação (p=0,02) em relação aos atletas com baixa visão. Na comparação quanto à modalidade esportiva, foi possível observar que os atletas de goalball oscilaram menos e apresentaram menor velocidade de deslocamento que os atletas de judô. Em paralelo, os jogadores de futebol de cinco foram aqueles que apresentaram melhor controle postural. As diferenças encontradas no controle postural de atletas com deficiência visual parecem estar associadas ao grau de perda visual e às especificidades das modalidades esportivas. Palavras-chave: Transtorno da visão. Equilíbrio postural. Plataforma de força.

“…The postural control system requires information from the visual, vestibular, and proprioceptive systems; the lack or inadequacy of the visual input affects the ability to maintain balance [2][3]. Additionally, it modifies normal gait patterns [4][5][6][7] and balance [8][9][10]. In order to compensate for the defective gait, further postural abnormalities develop, creating a vicious circle [11].…”

Purpose. The study is based on the hypothesis that individuals with congenital total or partial loss of vision develop more effective gait adjustments compared with those who are sighted, after stimulation of the vestibular system. Therefore, they are able to manage their motor control better. The aim was to investigate the way individuals with congenital total or partial vision loss adjust their gait following vestibular stimulation, compared with sighted blindfolded individuals. Methods. The total of 10 children with congenital visual impairments constituted the experimental group and 10 children with normal vision (blindfolded with special mask) formed the control group. We performed gait analysis (forward and backward gait direction) with a three-dimensional gait analysis system. The walking speed (m/s) of each group, before and after the vestibular stimulation, during forward and backward gait, was analysed. Results. The average walking speed of the children in the experimental group, statistically, revealed no significant differences before and after the vestibular stimulation. conversely, in the control group, statistically significant differences in the mean walking speed before and after the vestibular system stimulation were found. Conclusions. children with congenital total or partial blindness may adapt their gait strategy more adequately, after vestibular stimulation, during forward and backward gait, as compared with sighted blindfolded children. consequently, the first group is in the position to manage their motor control more sufficiently.
