摘要
目的：探讨头颈部疲劳因素对F波的影响特征,为长航时飞行航卫保障提供理论依据.方法：动态观察12名空军男性飞行学员（年龄22～24岁）佩带综合瞄准显示头盔装具（头瞄具）在地面模拟飞行8 h期间,头颈部疲劳对F波的影响,并与主观评价结果进行相关分析.结果：在模拟飞行状态下：①佩带头瞄具的头瞄组与未佩带头瞄具的非头瞄组在模拟飞行的第7小时以后,与第1小时比较,F波的平均潜伏期（Flat）延长,F波平均传导速度（Fvel）减慢,F波与M波平均潜伏期差值（IPL）增大,M波波幅（MA）增大,而头瞄组飞行员的Fvel较非头瞄组更是提前至第5小时即减慢;②头瞄组与非头瞄组比较,在模拟8小时持续飞行期间飞行员头颈部F波指标无显著变化.操作与非操作状态比较也无显著变化.结论：①Flat,Fvel,F-M IPL均为评价颈部疲劳的敏感指标;②佩带某型号头盔诱发颈部疲劳发生在持续模拟飞行的第5小时以后.
Objective：To investigate the characteristics of pilots＇F waves in cervical fatigue in duted by flight to provide the evidence for aero medical service. Methods：Characters of F waves in 12 male pilot trainees（aged 18-20 years old）affected by cervical fatigue were examined during 8 h simulating flight on the ground. Subjective evaluation on cervical fatigue was performed. Results： Compared with course of i h between groups with or without helmet aimed tools, Flat, IPL, MA increased, but Fvel decreased after simulating flight for 7 h. In the 5th hour Fret in the group with helmet aimed tools decreased compared with the group without helmet aimed tools. There were no significant changes of F waves between the 2 groups during 8 h simulating flight, and the change was the same as the statues. Conclusion： Flat,Fvel and IPL are both sensitive indices to evaluate cervical fatigue, which occurrs after the 5＇h hour during consecutive simulating flight when wearing helmet.
