[Purpose] This study aimed to explain the effect of a dual-task technology that utilizes motor and/or cognitive skills on the performance of major tasks, postural control, and gait consistency. [Participants and Methods] Eighteen healthy adults were divided into two groups: the single-word dual-task group and the control group (study 1). We enrolled 32 healthy adults to perform four-word Stroop (study 2) and sit-to-stand tasks simultaneously to determine the attentional demand for postural control and locomotion. [Results] The dynamic condition of postural control differed significantly between the single-task and single-word dual-task groups in Study 1. In Study 2, postural control in the four-word dual-task condition improved under both static and dynamic conditions. On comparing the results of studies 1 and 2, we found that during a four-word dual-task, healthy participants experienced a more significant decrease in postural sway than that experienced during the single-word dual-task. [Conclusion] Dual task of Stroop task with sit-to-stand could improve a postural control.
