Postural Control, Virtual Reality, Focus of Attention
Brief summary
The goal of this explorative observational study is to learn about the effect of internal and external focus on postural control in virtual reality and compare with the real world environment in young adults. The main question it aims to answer is: Does attentional focus effect differently on postural control in virtual reality comparing to real world environment?
Detailed description
Virtual Reality is used to improve postural control in various populations. However, exercise with virtual reality glasses cause new challenges to the user in maintaining balance. In this study, the effect of internal and external focus on postural control in the virtual reality environment will be revealed and compared with the performance in the real environment. The results of the study will guide the customization and optimization of balance training programs implemented in the virtual reality environment. A total of 38 healthy young adults will be included and allocated into Group I (Virtual Reality) or Group II (Real World) (ratio 1:1). The balance performance of the participants will be assessed with single leg stance test and bipodal stance test. The participants will be instructed to stand still and maintain balance on the forceplate in three conditions: (1) with an internal focus, (2) with an external focus, and (3) non-directional. Conditions will be applied to the participants randomly to avoid bias. Each condition will be measured three times and the mean values will be recorded as outcomes. The total displacement of center of pressure (CoP), the mean velocity of CoP, the CoP area, total mediolateral (ML) displacement, the mean velocity in ML, total anteroposterior (AP) displacement and the mean velocity in AP will assessed with K-Force Plates (Kinvent, France).
