The Relationship between Personality and Postural Control in Young Adults-A Pilot Study

Postural control is a term used to describe how the central nervous system regulates sensory information from other systems to produce adequate motor output to maintain a controlled, upright posture. Emotions (fear, anxiety) and thus personality type can affect the strategy of body control. This study aimed to evaluate the impact of personality on postural control. Thirty-three healthy individuals participated in this study. The big-five model was used to examine personality traits. Each participant performed four different standing tasks (one and both legs standing with eyes open (eo) and closed (ec): 2eo, 2ec, 1eo, 1ec). We showed that the dominant personality traits in the study group were extraversion and agreeableness. There were significantly low negative associations between nonlinear parameters and personality traits. A moderate correlation was noted for the 1eo trial between Openness and the Lyapunov exponent. In conclusion, nonlinear measures provide a possible link between personality and postural control. The relationships detected are weak. It shows that factors such as visual control and the size of the support area rather than personality will play a significant role in describing postural control.

Automated summary

This study aimed to evaluate the impact of personality on postural control. The results showed that extraversion and agreeableness were the dominant personality traits in the healthy individuals. There were significant negative associations between nonlinear parameters and personality traits, but the relationships detected were weak. Therefore, factors such as visual control and the size of the support area may play a more significant role in describing postural control.
