title: Assessment of intrasubject reliability of radiographic craniocervical posture of asymptomatic female subjects.
abstract: OBJECTIVE
  The objective of this study was to measure the reproducibility of the craniocervical posture (intrasubject reliability) of asymptomatic female subjects.
  
  
  METHODS
  Two radiographs of the craniocervical posture of 22 female subjects (mean ± SD: age, 28 ± 4.37 years; body mass index, 22.3 ± 3.24 kg/m(2)) in the sagittal view were taken 1 week apart and at the same time of day. Their posture was standardized in the self-balance position. Seven angles were measured in the digitalized radiographs and analyzed using the Alcimage software (Uberlândia, Minas Gerais, Brazil). Intraclass correlation coefficient (ICC), SEM, and 95% confidence intervals were analyzed.
  
  
  RESULTS
  Good-to-excellent ICC (ICC, 0.90-0.98) and small SEM (SEM, 0.25-0.70) were found.
  
  
  CONCLUSIONS
  The craniocervical posture of the subjects included in this study was reproducible (ie, intrasubject reliability) when measured a week apart using radiographs.
