We investigated the effect of this use on the cervical lordosis angle. MATERIAL AND METHODS: A group of 156 patients who applied with only neck pain between 2013–2016 and had no additional problems were included. Patients are specifically questioned about mobile phone, tablet, and other devices usage. The value obtained by multiplying the year of usage and the average usage (hour) in daily life was determined as the total usage value (an average hour per day x year: hy). Cervical lordosis angles were statistically compared with the total time of use. RESULTS: In the general ROC analysis, the cut-off value was found to be 20.5 hy. When the cut-off value is tested, the overall accuracy is very good with 72.4%. The true estimate of true risk and non-risk is quite high. The ROC analysis is statistically significant. CONCLUSION: The use of computing devices, especially mobile telephones, and the increase in the flexion of the cervical spine indicate that cervical vertebral problems will increase even in younger people in future. Also, to using with attention at this point, ergonomic devices must also be developed. Introduction Over the years, the use of tablets, mobile phones and interactive computing devices has increased. Social and business life is now almost a part of our lives, and after this point, our life will be more affected. We do not know the damages that the mobile phones give to the spine, especially cervical region, which makes our work easier and is a part of our daily life. In the age of we live, our posture of cervical flexion is increased. Many people use their phones for hours during the day with the increasing use of social media, and this has been taking place in our lives for almost 15-20 years. Also, the use of tablets and PC's is much higher. There is a need for flexion of the cervical region to use these devices, especially mobile phones. Increased cervical flexion has a negative effect on cervical lordosis. We tried to investigate the relationship between the duration of use and cervical lordosis. This is the first study to show how technological devices affect spinal alignment regarding usage time. Material and Methods Patients with a complaint of neck pain in the young age population who applied to our polyclinic between 2013 and 2016 and did not have any additional problems were included in this study. The age range of patients in the study is 25-42. Patients are specifically questioned about mobile phone, tablet, and other devices (as gaming consoles) usage. They were asked how many years they have been using and how many hours in a day they spent in the flexion /hyperflexion posture. The value obtained by
