The aim of this study was to determine if heightened stress had an adverse affect on the postural control of 14 young right-handed females during quiet standing in either the presence or the absence of visual input. The level of stress was evaluated by measuring the free cortisol response to awakening (cortisol awakening response; CAR) and by employing the perceived stress scale (PSS). Overall mood disturbance was measured using the profile of mood states (POMS). Postural control was evaluated using a force platform by measuring the 95% confidence ellipse area described by the center of pressure during 5 balance positions maintained for at least 52 sec, each with open and closed eyes. The results of this study revealed a significant positive correlation between CAR, PSS and POMS for each of the studied subjects. Furthermore, it was observed that whilst the level of stress was capable of influencing postural stability, this influence was particularly evident when no visual information was available. Additionally, it was determined that maintenance of posture is easier when the dominant foot is ahead, regardless of visual input.
