초록
Background: This study aimed to investigate the effects of saccadic eye movements on balance while standing on one leg, focusing on different frequencies (Fixation, .5㎐, 1.1㎐). Methods: This randomized controlled trial (RCT) included 41 healthy adults. Sample size was calculated using G*Power with an effect size of .25, alpha of .05, and power of .80, adjusted for a 10% dropout rate. Participants were randomly assigned to Fixation, .5㎐, or 1.1㎐ conditions. Balance metrics (SAE, AS, L) were measured using the BioRescue system (RM Ingénierie, Marseille, France), and eye movements were monitored with a Gazepoint GP3 HD Eye Tracker (Gazept, Vancouver, Canada). Results: Repeated Measures ANOVA showed significant differences among conditions for Surface Area Ellipse (F(2, 80)=5.049, p=.008), Average Speed of Sway (F(2, 80)=19.268, p<.000), and Length of Sway Path (F(2, 80)=20.742, p<.000). Post-hoc Tukey HSD tests indicated that the .5㎐ and 1.1㎐ conditions significantly reduced Average Speed of Sway and Length of Sway Path compared to Fixation. No significant differences were found in Surface Area Ellipse among the conditions. Conclusion: Saccadic eye movements at .5㎐ and 1.1㎐ can improve balance by reducing the average speed and length of sway. These findings suggest the potential role of visual stimuli in enhancing balance control, warranting further research into the underlying mechanisms and practical applications.
