24h睡眠剥夺对人体平衡能力的影响

Effects of 24h sleep deprivation on the ability of body balance

目的观察人体平衡能力在24h睡眠剥夺后的变化。方法观察16名健康男性在24h睡眠剥夺前后静态姿势图的变化。结果在24h睡眠剥夺后，睁眼时的动摇总轨迹长[0h：（564．40±42．07）mm，24h：（535．234±33．28）mm]、单位面积轨迹长[0h：（6．96±3．20）mm／mm。，24h：（5，49±2．65）mm／mm。]、左右动摇平均中心变位[0h：（7．01±2．79）mm，24h：（5．06±3．73）mm]显著性减少（P〈0．05），前后方向的标准偏差[0h：（3．17±0．83）mm，24h：（3．984-1．34）mm]显著性增加（P〈0．05）；闭眼时的动摇总轨迹长[0h：（645，70±80．05）mm，24h：（587，27±64．87）mm]显著性减少。结论24h睡眠剥夺后人体自发运动减少，控制平衡的能力减弱。

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. Resuits After 24h sleep deprivation, in hoth 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 ：L 64.87 ） significamly decreased. Conclusion After 24h sleep deprivation, there are less spontaneous movements of body and lower efficiency of postural control.
