摘要：

Purpose To investigate the different cervical strategies for maintaining horizontal gaze in asymptomatic subjects. Methods One hundred and forty-four asymptomatic adults filled the SF-36 quality of life questionnaire and underwent full-body biplanar radiographs. Chin brow vertical angle (CBVA) and postural and cervical parameters were measured. Subjects were grouped according to cervical spine curvature (C2-C7 angle): kyphotic (< -5 degrees), straight [-5 degrees, 5 degrees], lordotic (> 5 degrees). Demographics, SF-36 component scores and CBVA were compared between groups. All other parameters were compared between groups, while controlling for confounding factors (ANCOVA). A correlation test was conducted between all cervical parameters. Results 32% of subjects had kyphotic (-12 degrees +/- 7 degrees), 27% straight (0 degrees +/- 3 degrees) and 41% lordotic (12 degrees +/- 7 degrees) cervical spines. While demographic and SF-36 data did not differ between groups, CBVA differed between lordotic and kyphotic groups (2 degrees vs. 6.5 degrees, p = 0.002). Sagittal vertical axis (SVA) and thoracic kyphosis (TK) were lower in the kyphotic group (SVA: K = -26 +/- 20 mm vs. L = -2 +/- 21 mm, p < 0.001; TK: K = 40 degrees +/- 6 degrees vs. L = 51 degrees +/- 8 degrees, p < 0.001). C2 slope (K = 29 degrees +/- 6 degrees vs. L = 18 degrees +/- 6 degrees, p < 0.001), C0-C2 (K = 42 degrees +/- 8 degrees vs. L = 30 degrees +/- 8 degrees, p < 0.001) and C1-C2 (K = 33 degrees +/- 6 degrees vs. L = 28 degrees +/- 6 degrees, p = 0.004) were higher in the kyphotic group. Significant correlations were found between almost all cervical parameters and C2-C7 angle. Conclusions Subjects with cervical kyphosis presented with more posterior global alignment and lower TK than subjects with lordosis. In order to maintain horizontal gaze, subjects with cervical kyphosis presented with a more lordotic upper cervical spine than subjects with cervical lordosis. Subjects with straight cervical curvature presented with an intermediate sagittal alignment.
