Clinical status of computerized dynamic posturography in neurotology

Computerized dynamic posturography, as defined by the American Academy of Otolaryngology–Head and Neck Surgery and the American Academy of Neurology, isolates and quantifies sensory and motor contributions to balance control and assesses sensorimotor integration in people with normal and abnormal sensorimotor skills. Clinical computerized dynamic posturography applications include (1) differentiation of vestibular, visual, and somatosensory impairments to postural control; (2) differentiation of peripheral sensory and central nervous system postural control abnormalities; (3) isolation of sensory and motor components of postural instability associated with neurologic disorders; (4) documentation of age-related changes in balance function (including falls in the elderly); (5) differentiation of organic balance problems versus aphysiologic postural sway; (6) selection of candidates for rehabilitation; (7) quantitative monitoring of management outcome; and (8) assessment of the effects of novel motion environments, including spaceflight (microgravity), on human balance function.
