title: [An transcranial Doppler ultrasonography and X-ray study of cervical vertigo patients treated by manipulation in supine position].
abstract: OBJECTIVE
  To observe the transcranial Doppler ultrasonography and X-ray changes of cervical vertigo patients caused by cervical instability before and after the manipulation treatment in supine position.
  
  
  METHODS
  Sixteen cervical vertigo patients who underwent supine manipulation treatment were reviewed retrospectively. After the treatment, the changes of transcranial Doppler ultrasonography of cervical vertebral artery and X-ray of cervical spine were observed.
  
  
  RESULTS
  Before the treatment, the mean blood flow velocity of vertebral artery was (48.6+/-3.1) cm/s, much higher than that of the normal group (P<0.05), the means of the horizontal displacement of C3,4 and C4,5 were (3.18+/-0.42) mm and (3.46+/-0.26) mm respectively. After the treatment, the blood flow velocity and the C3,4 horizontal displacement decreased significantly (P<0.05). The effective rate of the manipulation treatment was 100%.
  
  
  CONCLUSIONS
  The manipulation treatment is an effective method for cervical vertigo patients caused by cervical instability, and the effect is correlated with the improvement of the blood flow of cervical artery and the restoration of cervical stability.
