Purpose: This study aimed to investigate the effects of eye gaze direction during rotation on the thickness of the cervical deep flexor muscles. Methods: Thirteen healthy adults in their twenties were recruited for this study. They were instructed to rotate their necks by 45 °under three conditions: maintaining a forward gaze, moving their gaze along with the head, and closing their eyes. Ultrasonography was performed to measure the thickness of the deep neck flexors during these movements. Data from each condition were analyzed using one-way repeated measures analysis of variance (ANOVA), with post hoc comparisons were performed using the Bonferroni correction. The statistical significance level was set at p < 0.05 or less. Results: There was a statistically significant difference in the thickness of the deep neck flexor muscles when participants maintaining a forward gaze during neck rotation (p < .05). However, when maintaining a 45-degree gaze during neck rotation, there was no statistically significant difference (p < .05). Similarly, there was no statistically significant difference in muscle thickness when participants closed their eyes during neck rotation (p < .05). Conclusion: The results of this study demonstrate that maintaining a forward gaze during neck rotation increases the thickness of the deep neck flexor muscles. These findings indicate that maintaining a forward gaze during neck rotation could serve as an effective exercise for enhancing neck stability during movement.
