Symposium Overview
Postural instability and falls occur when normal spatial orienting and postural mechanisms are challenged and fail. Perception of spatial orientation primarily involves the transduction and integration by the central nervous system (CNS) of sensory information from visual, vestibular, proprioceptive, somatosensory and auditory systems. Optimal integration of sensory signals and body movements required to maintain one’s desired orientation in 3-dimensional space, even for static body positions, is a necessarily complex task. When moving through one’s environment, during which the majority of falls occur, successful postural control further relies on the dynamic comparison of sensorimotor information with “higher order” control signals concerned with predictive route planning, expectations about movement and memory of one’s path. The penetrability of perceptual processes by factors such as attention, memory and decision-making suggests that successful control of postural stability is likely to involve cognitive processing. Despite a great deal of recent research effort directed towards addressing the multivariate predictors of falls in older individuals, there has yet to be a systematic study of this area from a coherent theoretical perspective of multisensory integration and spatial orientation.
The motivation for this symposium is to present the work done by a number of Internationally recognised research teams who are interested in the multisensory mechanisms of posture control.
