Evaluation of Mobile Phone Addiction Scale Score and it’s Correlation with Craniovertebral Angle and Neck Disability in Young Adults - A Cross- Sectional Analytical Study

Background
Worldwide technology and its changes play a major role in each individual‟s life. Mobile phone is considered as an important communication tool and became the integral part of the society, it is not only a communication device but it also a necessary social accessory. The bending moment of the head applies pressure on muscles and joints around the cervical vertebra, in addition to active myofascial trigger points of the suboccipital muscle which may induce tension type headaches, neck pain and cervical headaches, while reducing the mobility of the neck.

Aim
To evaluate mobile phone addiction scale score and it‟s correlation with craniovertebral angle and neck disability in young adults.

Methods
In this cross sectional study, 100 young adults were recruited from medical college. Subjects were evaluated or assessed for mobile phone addiction using mobile phone addiction scale, craniovertebral angle were measured using MB ruler software and neck disablity was assessed using neck disability index. After all measurements were taken, the correlation between mobile phone addiction scale and craniovertebral angle, mobile phone addiction scale and neck disability was carried out.

Results
Pearson‟s correlation coefficient test was conducted between mobile phone addiction scale score and craniovertebral angle (r = -0.6786, p = < 0.0001), mobile phone addiction scale score and neck disability index (r = 0.6170, p< 0.0001) i.e extremely significant. Hence there is a significant correlation between these variables.

Conclusion
The study demonstrated that there was a significant correlation between mobile phone addiction scale score and craniovertebral angle, mobile phone addiction scale score and neck disability index. Also we found that as highest the mobile phone addiction scale score a young adults had, they are more prone to develop forward head posture and neck pain.

背景
全球科技进步及其变革在每个人的生活中扮演着举足轻重的角色。手机被视为一种重要的通讯工具，已成为社会不可或缺的一部分，它不仅是一种通讯设备，更是一种必要的社交配件。头部前倾所产生的弯矩对颈椎周围的肌肉和关节施加压力，此外，枕下肌的活跃肌筋膜触发点可能引发紧张型头痛、颈部疼痛和颈椎病，同时降低颈部活动性。
目标
本研究旨在评估年轻成人中手机成瘾量表得分与其颅椎角和颈部功能障碍的相关性。
方法
在本项横断面研究中，从医学院招募了100名年轻成人。使用手机成瘾量表对受试者进行评估或评估其手机成瘾程度，使用MB尺软件测量颅椎角，使用颈部功能障碍指数评估颈部功能障碍。在所有测量完成后，进行了手机成瘾量表得分与颅椎角、手机成瘾量表得分与颈部功能障碍之间的相关性分析。
结果
对手机成瘾量表得分与颅椎角（r = -0.6786，p < 0.0001）、手机成瘾量表得分与颈部功能障碍指数（r = 0.6170，p < 0.0001）进行了皮尔逊相关系数检验，即具有极其显著的统计学意义。因此，这些变量之间存在显著的相关性。
结论
本研究证实，手机成瘾量表得分与颅椎角、手机成瘾量表得分与颈部功能障碍指数之间存在显著相关性。此外，我们发现，手机成瘾量表得分越高的年轻成人，越容易发展出前倾头位和颈部疼痛。
