title: [Complementation of head shaking nystagmus and bithermal caloric test].
abstract: OBJECTIVE
  To investigate the complementary relation between head shaking nystagmus (HSN) and bithermal caloric test.
  
  
  METHODS
  All of the 60 patients with vertigo were tested with bithermal caloric test, HSN and audiological tests.
  
  
  RESULTS
  There were 19 patients with normal CP and HSN, in which 8 had shared the same direction (towards the uninjured side) and 11 indicated opposite direction(HSN towards the lesioned side). Ten patients had normal CP with no HSN. Eight patients had abnormal CP and no HSN. In 23 patients with abnormal CP and HSN, HSN in 19 patients had opposite direction against that of CP and HSN in 4 patients had the same direction with that of CP (towards the lesioned side).
  
  
  CONCLUSIONS
  HSN and bithermal caloric test had the complementary effects and it is helpful to interpret the vestibular function more accurately if they are applied together.
