[Purpose] This study compared the symmetry of right and left lateral cervical flexion and rotation, and the cervical flexion-relaxation ratio (FRR) in young computer workers in Korea. [Subjects and Methods] Twenty computer workers (14 males and 6 females) participated in this study. We measured their right and left lateral cervical flexion, rotation, and FRR. [Results] Right and left lateral flexion and right and left rotation showed no significant differences between the sides. The left cervical FRR was significantly lower than the right cervical FRR. [Conclusion] The cervical FRR, expressed as a numerical value, is a more sensitive marker for measuring neuromuscular changes associated with mild asymmetry than CROM.
[目的] 本研究比较了韩国年轻电脑工作者左右侧颈椎侧屈和旋转的对称性,以及颈椎屈伸松弛率(FRR)。[对象与方法] 20名电脑工作者(14名男性和6名女性)参与了本研究。我们测量了他们的左右侧颈椎侧屈、旋转和FRR。[结果] 左右侧侧屈和左右侧旋转在两侧之间无显著差异。左侧颈椎FRR显著低于右侧颈椎FRR。[结论] 以数值表示的颈椎FRR是比CROM更敏感的测量与轻度不对称相关的神经肌肉变化的指标。
