title: [Characteristics of computed dynamic posturography of patients with peripheral vertigo].
abstract: OBJECTIVE
  To quantify the posture control ability of patients with peripheral vertigo by computed dynamic posturography (CDP).
  
  
  METHODS
  Ninety-one subjects diagnosed with peripheral vertigo by caloric test were divided into unilateral vestibular dysfunction group (unilateral group) and bilateral vestibular disorder dysfunction group (bilateral group). CDP tests including sensory organization test (SOT) and motor control test (MCT) were performed on all subjects. The CDP results were compared with the normal data by t-test.
  
  
  RESULTS
  In unilateral group, there was no statistically significant difference in SOT compared with normal data (P > 0.05). In bilateral group, the composite equilibrium score was lower than the normal data, especially during the moving of the platform and the changes of visual stimulation (P < 0.05). In MCT test, the latencies of both groups showed no statistically significant difference compared with normal data (P > 0.05).
  
  
  CONCLUSIONS
  During the non-acute period of peripheral vertigo, patients could maintain static equilibrium. Compared with normal people, dynamic equilibrium function is normal in patients with unilateral vestibular dysfunction, but declined in patients with bilateral vestibular dysfunction.
