title: Ampleness of head movements of children and adolescents with sensorineural hearing loss.
abstract: BACKGROUND
  Head movements are controlled by the vestibular system. Children with sensorineural hearing loss can present restrictions in ampleness of head movements due to damage in the vestibule-cochlear systems, resulting from injury in the inner ear.
  
  
  OBJECTIVE
  To evaluate the ampleness of head movements of children with normal hearing and children with sensorineural hearing loss and compare data between groups.
  
  
  METHODS
  Cross-sectional study that evaluated the ampleness of head movements of 96 students, being 48 with normal hearing and 48 with sensorineural hearing loss, of both sexes, with aged between 7 and 18 years old. The performance of ampleness of head movements was analyzed by a manual goniometric evaluation, according the references proposed by Marques. To the statistical analysis we used the t-Student test in case of normality of the data or the Mann-Whitney test when did not applied the suppositions of normality.
  
  
  RESULTS
  Hearing loss children showed less mean in ampleness of all movements of head compared to normal hearing children, pointing difference to movements of flexion (p = 0,001), lateral inclination to the right (p = 0,025) and lateral rotation to the left (p = 0,021).
  
  
  CONCLUSIONS
  Hearing loss children showed reduction in the ampleness of these head movements: flexion, lateral inclination to the right and lateral rotation to the left compared to normal hearing children.
