Functional Neurological Assessment: Computerized Dynamic Posturography (Flight Analog) (MR042G)

Description
OBJECTIVES:
The objective of the Functional Neurological Assessment measure was to assess changes in motor coordination and sensory integration. The goals of this Standard Measure were to: (1) characterize changes in postural control following long-duration head-down tilt bed rest, compare these changes to responses following space flight, and (2)to provide a functional assessment of the sensorimotor effects of candidate countermeasures. This standard measure utilized computerized dynamic posturography (CDP) to quantitatively assess both sensory and motor components of postural control. The Sensory Organization Tests (SOTs) objectively evaluated one’s ability to make effective use of (or suppress inappropriate) visual, vestibular, and proprioceptive information for balance control. The Motor Control Tests (MCTs) evaluated one's ability to automatically recover from unexpected support surface perturbations.
