Influence of optic flow on a sit-to-stand task in healthy children and adults

Abstract

Children and adults stood from a seated position in the dark, with the onset of visual scene motion or after a period of immersion in the virtual reality environment. Multiplanar head and trunk angular velocity were calculated. Both children and adults were found to reduce head and trunk angular velocities when immersed in a moving visual field but not when standing coincident with the onset of visual motion.
