[Purpose] The purpose of this study was to compare cervical repositioning errors according to smartphone addiction grades of adults in their 20s. [Subjects and Methods] A survey of smartphone addiction was conducted of 200 adults. Based on the survey results, 30 subjects were chosen to participate in this study, and they were divided into three groups of 10; a Normal Group, a Moderate Addiction Group, and a Severe Addiction Group. After attaching a C-ROM, we measured the cervical repositioning errors of flexion, extension, right lateral flexion and left lateral flexion. [Results] Significant differences in the cervical repositioning errors of flexion, extension, and right and left lateral flexion were found among the Normal Group, Moderate Addiction Group, and Severe Addiction Group. In particular, the Severe Addiction Group showed the largest errors. [Conclusion] The result indicates that as smartphone addiction becomes more severe, a person is more likely to show impaired proprioception, as well as impaired ability to recognize the right posture. Thus, musculoskeletal problems due to smartphone addiction should be resolved through social cognition and intervention, and physical therapeutic education and intervention to educate people about correct postures.
[目的]本研究旨在比较20多岁成年人根据智能手机成瘾程度的颈椎重新定位误差。[对象与方法]对200名成年人进行了智能手机成瘾调查。根据调查结果，选取30名受试者参与本研究，并将他们分为三组，每组10人；正常组、中度成瘾组和重度成瘾组。在佩戴C-ROM后，我们测量了颈椎在屈曲、伸展、右侧侧屈和左侧侧屈时的重新定位误差。[结果]在正常组、中度成瘾组和重度成瘾组之间，颈椎在屈曲、伸展以及左右侧屈时的重新定位误差存在显著差异。特别是，重度成瘾组的误差最大。[结论]结果表明，随着智能手机成瘾程度加重，一个人更有可能出现本体感觉受损以及正确姿势识别能力受损的情况。因此，应通过社会认知和干预以及物理治疗教育和干预来解决因智能手机成瘾导致的肌肉骨骼问题，以教育人们正确的姿势。
