Transient effects exist during eyes closed and eyes open quiet stance although characteristics vary

Although transient behavior has been reported for commonly used center of pressure parameters, the physiological relevance of this behavior is unclear. This study investigated these transient effects during eyes open and eyes closed stance in a healthy population. Although initial transient effects were found in both eyes open and eyes closed conditions, the effects were magnified during eyes closed stance. This suggests that aspects of the transient response may be due to altering the sensory input via loss of visual information, but this effect does not provide a complete explanation.
