Resumo: Several structures of the central nervous system share involvement in both ocular and postural control, but the visual mechanisms in postural control are still unclear. There are discrepant evidences on whether saccades would improve or deteriorate stabilization of posture. The purpose of this study was to determine the influence of saccadic eye movements on postural control while standing in different basis of support. Twelve young adults stood upright in wide and narrow stances while performing fixation and saccades of low and high frequencies. Body sway was attenuated during saccades. Trunk anterior-posterior sway and trunk total displacement decreased during saccades compared to fixation; higher sway mean frequency in anterior-posterior direction during saccades was observed. Body sway was reduced in wide compared to narrow stance during high frequency saccades. These results indicate that eye movement improves postural stabilization and this effect is stronger in combination of wide stance-high frequency gaze condition.

Existem evidências discrepantes sobre a possibilidade de movimentos sacádicos melhorarem ou deteriorarem a estabilização postural. O objetivo desse estudo foi determinar a influência de movimentos sacádicos dos olhos sobre o controle postural em diferentes bases de apoio. Doze adultos jovens ficaram em pé, mantendo a postura sobre base ampla e restrita enquanto realizavam fixações e movimentos sacádicos de baixa e alta frequência. Oscilação corporal foi atenuada durante movimentos sacádicos. A oscilação do tronco na direção ântero-posterior e o deslocamento total do tronco diminuíram durante movimentos sacádicos comparados à fixação; maior frequência média de oscilação na direção ântero-posterior durante movimentos sacádicos também foi observada. Oscilação corporal foi reduzida em postura com base ampla comparada à restrita durante movimentos sacádicos de alta frequência. Estes resultados indicam que o movimento do olho melhora a estabilização postural e este efeito é mais forte na condição que combina base ampla e alta frequência do olhar.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Sao Paulo State Univ, Sao Paulo, BrazilCruzeiro do Sul Univ, Sao Paulo, BrazilUniv Fed Sao Carlos, BR-13560 Sao Carlos, SP, BrazilUniv Sao Paulo, BR-05508 Sao Paulo, BrazilSao Paulo State Univ, Cruzeiro do Sul Univ, Sao Paulo, BrazilSao Paulo State Univ, Sao Paulo, BrazilSao Paulo State Univ, Cruzeiro do Sul Univ, Sao Paulo, BrazilFAPESP: 09/00899-8Universidade Estadual Paulista (Unesp), Instituto de BiociênciasUniversidade Estadual Paulista (Unesp)Cruzeiro do Sul UnivUniversidade Federal de São Carlos (UFSCar)Universidade de São Paulo (USP)Rodrigues, Sérgio Tosi [UNESP]Aguiar, Stefane AlinePolastri, Paula Fávaro [UNESP]Godoi, DanielaMoraes, RenatoBarela, Jose Angelo [UNESP]2014-12-03T13:09:13Z2014-12-03T13:09:13Z2013-01-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article614-619application/pdfhttp://dx.doi.org/10.1590/S1980-65742013000300012Motriz: revista de Educacao Física.
