title: [Assessment of dynamic posture equilibrium function after traumatic brain injury].
abstract: OBJECTIVE
  To explore characteristics and causes of equilibrium function deficits after traumatic brain injury(TBI).
  
  
  METHODS
  Ninety-five patients after TBI in traffic accidents were tested using computerized dynamic posturography (CDP). The CDP findings of patients were compared with normal value. The patients were grouped based on TBI and audition disorders degrees. The results were compared within the patients groups.
  
  
  RESULTS
  The equilibrium scores of the TBI group were significantly lower than the normal value. The utilization rate decreased for vision and vestibular sensation information in the TBI group, especially for vestibular sensation. The primary TBI degree and audition decrease had no significant affect on posture stability.
  
  
  CONCLUSIONS
  The poor posture stability was observed in TBI patients without limbs disturbance. The response and adaptation abilities decrease in these patients. This could be explained by the damage to peripheral vestibular and central balance structures.
