ABSTRACT
Objective:
To explore the role of static posturography in the assessment of fatigue due to flight tasks.Methods:
Thirtymale college students were asked to perform simulated flight tasks consecutively forfour hours.Meanwhile their statie posturography and tasks performance would be repeatedly measured during the task-load at end of every hour.Based on the changed significantly parameters,the static balance index would be built by principle component analysis.Then its correlation with task-load level would be further analyzed by curve estimation.Results:
Static postural control declined significantly under effect of simulated flight tasks.With task load sustaining,static balance index increased significantly and correlated linearly with duration of task load (R2=0.949).Besides,there was quadratic relationship between the change of multi-tasks performance and duration of task load (R2=0.968).And correlation of multi-tasks performance with static standing balance level also had been proved to be quadratic (R2=0.976).Conclusions:
Static posturography correlated linearly with flight task-load level,which could reflect fatigue level caused by task load.
