Abstract
[Purpose] This study compared the cervical range of motion and cervical FRR between computer users in their early and late 20s in Korea. [Subjects] Eleven male and 7 female computer users in their early 20s and 10 male and 6 female computer users in their late 20s participated in this study. [Methods] All cervical ROM measurements were taken with a Cervical Range of Motion Instrument. Electromyographic (EMG) data were obtained for analyzing the FR ratio. [Results] Cervical extension, right and left lateral flexion, and right and left rotation in the late 20s computer users were significantly lower compared with the cervical motions in the early 20s computer users. The cervical FRR in the late 20s computer users was significantly lower compared with the cervical FRR in the early 20s computer users. [Conclusion] This study was conducted to be prepared that the possibility for young computer generations in Korea could easily develop chronic neck pain.
