Abstract:
:This multisite investigation assessed subjective, behavioral, and objective balance function in 30 blast survivors. Subjects with vertigo, dizziness, or imbalance were screened (n = 6) or evaluated (n = 27) during 1 year. Tests included a questionnaire, electronystagmography (ENG), and computerized dynamic posturography (CDP). Ninety-seven percent of subjects were located inside a building during the blast, and 63 percent of subjects experienced dysequilibrium within 48 hours. Forty-three percent of symptoms could not be attributed to head injury. Sixty percent of subjects had abnormal ENG and/or CDP; ENG abnormalities mostly were peripheral or nonlocalizing, whereas CDP patterns were "vestibular," "surface dependent," and "physiologically inconsistent." At 1-year postblast, 55 percent of initially abnormal CDP results were normal, and 72 percent of subjects said symptoms were unchanged or occurred intermittently. A serial, test battery approach is recommended to assess symptoms. Blast-related dysequilibrium had clinically significant manifestations and should be considered a valid component of aural blast injury.
