Introdução: O controle postural é um comportamento sensório-motor complexo que consiste na habilidade de controlar o corpo no espaço em relação ao ambiente. Objetivo: Investigar, por meio de revisão da literatura, a influência do medo de quedas sobre o controle postural ortostático em indivíduos saudáveis. Material e métodos: Nove artigos foram selecionados, os demais artigos foram utilizados na contextualização do tema proposto. Resultados: Estudos que realizaram mudanças no ambiente, em que os participantes foram posicionados em plataformas hidráulicas elevadas a diferentes alturas, evidenciaram uma diminuição da oscilação postural na condição em que a plataforma estava elevada. Esta mudança no controle postural tem sido correlacionada com o medo de queda, que pode modular a atividade do fuso neuromuscular (reflexo-H) e induzir a um fenômeno de congelamento postural. Parece que este fenômeno de congelamento postural representa um tipo de ansiedade antecipatória diante de uma situação adversa (plataforma elevada). Conclusão: Mais estudos são necessários para compreender os mecanismos envolvidos neste tipo de fobia (medo de quedas) e sua relação com o controle postural, a fim de traçar estratégias para o seu diagnóstico precoce, tratamento e prevenção.
Palavras-chave: medo, quedas, equilíbrio postural.
