目的 对军事飞行员前庭功能稳定性进行评价，为军事飞行员前庭功能稳定性训练提供依据。 方法 应用电动转椅对军事飞行员进行前庭功能稳定性训练。按照入院顺序，分别选取21~30岁、31~40岁、41~50岁、≥51岁年龄段各30名飞行员，比较不同年龄段飞行员训练前后前庭功能稳定性的优秀率、良好率、合格率、不合格率以及耐受时间变化，并分析年龄与耐受时间的相关性。 结果 31~40岁、≥51岁组飞行员训练前后不合格率比较差异有统计学意义（χ2=4.32、4.80，P=0.038、0.028）。飞行员前庭功能稳定性训练后不合格率较训练前降低，差异有统计学意义（χ2=13.02，P<0.001）。总耐受时间均较训练前增加，差异有统计学意义（t=17.61，P<0.001）。不同年龄组飞行员前庭功能训练后其稳定性耐受时间均较训练前增加，差异有统计学意义（t=6.50、8.82、9.48、13.56，P均<0.001）。随着年龄的增加，前庭功能稳定性逐步减退，年龄与训练耐受时间呈负相关（r=-0.38，P<0.001）。 结论 电动转椅训练可增强军事飞行员前庭功能稳定性，增加耐受时间，提高前庭功能受到刺激时的耐受能力。 Objective To provide references for the vestibular function stability training of military pilots by evaluating the stability of vestibular function of military pilots. Methods An electric swivel chair was used to train the vestibular function stability of military pilots. According to the order of admission, they were divided into 21-30 years old, 31-40 years old, 41-50 years old and ≥51 years old group, with 30 pilots in each group. The changes of excellent rate, good rate, qualified rate, unqualified rate and tolerance time of the stability of vestibular function by training were compared among different age groups, and the correlation between age and tolerance time was analyzed. Results There were significant differences of unqualified rate in pilots aged 31-40 and ≥51 years group before and after training (χ2=4.32, 4.80, Ρ=0.038, 0.028). The failure rate after training was lower than that before training, with a significant difference (χ2=13.02, P<0.001). The total tolerance time was higher than that before training, and the difference was statistically significant (t=17.61, P<0.001). The stability tolerance time of pilots in different age groups after vestibular function training were increased compared with that before training, and the differences were statistically significant (t=6.50, 8.82, 9.48, 13.56, all P<0.001). The stability of vestibular function of military pilots gradually declined with the increase of age, and there was a negative correlation between age and training tolerance time (r=-0.38, P<0.001). Conclusions The training of electric swivel chair can improve the vestibular function stability of military pilots, increase the tolerance time, and enhance the tolerance ability of military pilots when vestibular function is stimulated.
