AB - Purpose : This study uses X-rays investigate how university students' smart phone use affects the cervical vertebral angle. Methods : Ninety-two randomly selected students agreed to participate in this study. The participants' number of hours of smart phone use was gathered using a questionnaire. An X-ray of the participants' cervical vertebrae was taken, and the cervical vertebral angle was measured using the Cobb and the absolute rotation angle (ARA) method. Also, the relation between pain and hours of smart phone use was identified using a visual analog scale (VAS). Using SPSS ver18, the relationships among the cervical vertebral angle and the items in the questionnaire were identified and a frequency analysis, an independent t-test, and the analysis of variance (ANOVA) were calculated. Results : The study showed that an increase in the number hours of smart phone per day led to cervical lordosis(p<0.05). The relationships between points of smart phone addiction and cervical vertebral angle have a negative correlation (p<0.05). Therefore, there are the higher smart phone addiction points, the decrease the cervical vertebral angle. Conclusion : The results of the study showed that increase in smart phone use lead to cervical lordosis, and smart phone addiction scores resulted in decreased in the cervical vertebral angle.
