title: The Influence of Fear of Falling on Orthostatic Postural Control: A Systematic Review.
abstract: Posture is a complex sensory-motor behavior that can be influenced by the fear of falling (FoF) during environmental changes. The aim of this paper is to investigate the influence of FoF on orthostatic postural control in healthy individuals by a systematic review. Thirteen articles were selected. Some other articles (31 references) were used to contextualize and discuss the topic. Studies in the environment made changes on the environment, in which participants were positioned in high hydraulic platforms at different heights, showed a decrease in the center of pressure in the anteroposterior oscillation where the platform was higher. This change in postural control strategy and the FoF are correlated. It can modulate the activity of the muscle spindle (H-reflex) and probably induce postural freezing phenomenon (anticipated postural anxiety). We can conclude that further studies are needed to understand the physiological echanisms involved in FoF and its relation to changes in postural control strategy.
