Effects of 24h sleep deprivation on the ability of body balance / 中国行为医学科学

ABSTRACT

Objective To analyse the efficiency of postural control after 24h sleep deprivation.Methods To observe the change of the static posturography of 16 healthy male after 24h sleep deprivation.Results After 24h sleep deprivation,in both eyes-open condition,whole path length(0h:564.40±42.07,24h:535.23±33.28),unit-path-length(0h:6.96±3.20,24h:5.49±2.65),deflection average center displacement X (0h:7.01±2.79,24h:5.06±3.73)significantly decreased,but standard deviation Y(0h:3.17±0.83,24h:3.98±1.34)significantly increased.In both eyes-closed condition,whole path length(0h:645.70±80.05,24h:587.27±64.87)significantly decreased.Conclusion After 24h sleep deprivation,there are less spontaneous movements of body and lower efficiency of postural control.
