[Purpose] The purpose of this study was to evaluate the effect of modified cervical exercise and determine whether such exercise improves the range of motion of the cervical movement in smartphone users with forward head posture. [Subjects and Methods] Some 32 subjects with forward head posture participated in this study. They were randomly allocated to three groups, and the modified cervical exercises were performed either once, twice, or three times per day. The exercise program was followed for four weeks and then the joint range of motion of the participants was measured. [Results] A significantly increased range of motion was seen in all three groups that performed the modified cervical exercises. The analysis of the effects among the three groups indicated that the greatest effect was seen in Group C, members of which performed the modified exercises three times per day. In addition, a significant difference was found between Group A and Group C in terms of the inter-group results. [Conclusion] According to the results of this study, although the modified cervical exercises were performed for only a relatively short duration (four weeks), the exercises brought about an improvement in the forward head posture that was induced by using a smartphone.
[目的] 本研究旨在评估改良颈椎运动的效果，并确定该运动是否能改善头部前倾姿势的智能手机使用者的颈椎活动范围。[对象与方法] 约32名头部前倾姿势的受试者参与了本研究。他们被随机分为三组，改良颈椎运动分别每天进行一次、两次或三次。运动方案持续四周，然后测量参与者的关节活动范围。[结果] 进行改良颈椎运动的所有三组受试者的活动范围均显著增加。三组之间的效果分析表明，C组效果最佳，该组受试者每天进行三次改良运动。此外，A组和C组的组间结果存在显著差异。[结论] 根据本研究结果，尽管改良颈椎运动仅进行了相对较短的时间（四周），但该运动改善了因使用智能手机导致的头部前倾姿势。
