The purpose of this study was to determine whether heightened stress may adversely affect the postural control in 14 young right-handed women during quiet standing with and without visual input. Level of stress was evaluated by measuring free cortisol response to awakening (Cortisol Awakening Response, CAR) and by administering the Perceived Stress Scale (PSS), whereas the Profile of Mood States (POMS) was utilized to measure overall mood disturbance. The postural control was evaluated with a force platform by measuring 95% confidence ellipse area described by the Center of Pressure during five balance positions maintained for at least 52 s with open and closed eyes. Results showed that there is a strong significant positive relation between POMS, PSS and CAR for each studied subjects. Moreover, it has been observed not only that the level of stress is capable of influencing postural stability, but also that this influence is especially evident when postural control cannot use visual information. Finally, it was detected that the maintenance of posture is easier when the dominant foot is ahead, regardless of visual input.
