Purpose: The purpose of this study is an investigation of the changes in static balance and gait parameters after treadmill walking with using a smartphone in various head positions. Methods: The subjects of this study were 20 healthy college students (7 male, 13 female). Subject walked in treadmill at the speed of 2km/h for 3 minutes without using smartphone and with both hands using smartphone in straight ahead and down head. During the task, static balance and gait parameters were collected. A one-way repeated analysis of variance with the level of a significant level of .05 was used. And Bonferroni correction (α=.05/3=.0017) executed to evaluate the significance of between-exercise pairwise comparisons. Results: Our result presented that center of gravity way velocity sway velocity and total sway distance with the eyes closed on the unstable sponge surface, ware significantly greater in walking without using a smartphone condition than head straight ahead. There were no significant differences in gait parameter. Conclusion: Walking with straight ahead would enhance the equilibrium information and cause a positive effect on static balance only
