Abstract

Objectives This study was designed to compare curvature and intervertebral disc angle of the cervical spine in different prone positions. Methods 30 adults aged 19~60 years were enrolled in this study. Volunteers in this uncontrolled trial were taken an x-ray of cervical spine on lateral. Four radiographs were taken for each volunteer, in standing, prone position with U-type pillow (prone position A), rectangular pillow (prone position B), and prone position without pillow (prone position C). After measuring the cervical angle, Ishihara index, craniovertebral angle, intervertebral angle, we analysed the lordotic angle and foward head posture. The data was anlysed by analysis of variance and pearson correlation coefficient. Results Cervical angles of prone position without pillow (prone position C) significantly decreased compared with those in standing position (p<0.001). Ishihara index of prone position without pillow (prone position C) also significantly decreased compared with those in standing position (p<0.001). Craniovertebral angle of prone position with pillow (prone position A, B) significantly increased with those in standing position (p<0.001). Intervertebral angle of prone position with pillow (prone position A, B) at the C3-7 levels significantly increased with those in standing position (p<0.001). Intervertebral angle of prone position without pillow (prone position C) at the C3-5 levels significantly decreased with those in standing position (p<0.001). The angle of intervertebral disc significntly decreased in kyphotic cervical levels. Conclusions Different prone position clearly resulted changes in cervical spine curvature and intervertebral disc angle. And it is related to cervical spine lordotic angle and sagittal alignment in standing position and prone position.
