目的旨在探讨空降兵的前庭功能特征及跳伞对前庭功能的影响。方法用眼震电图仪检查了２０７名空降兵和９２名陆军通信兵（对照组）的位置性眼震。结果空降兵的位置性眼震发生率明显高于通信兵（Ｐ＜０．０１），其眼震强度亦大于通信兵（Ｐ＜０．０５），随跳伞次数的增多眼震强度增大的人数增加（Ｐ＜０．０１），不同跳伞次数与位置性眼震的发生率有非常显著性差异（Ｐ＜０．０１）。结论跳伞可损伤前庭功能，并提出了评价跳伞所致前庭功能障碍的四项指征
Aims To investigate the vestibular function of parachutists and the impact of skydiving on vestibular function. Methods The nystagmus of 207 airborne and 92 Army Corps soldiers (control group) was examined with electronystagmography. Results The incidence of positional nystagmus was significantly higher in the airborne units than that in the telecommunication soldiers (P <0.01), and its nystagmus intensity was also greater than that of the communication soldiers (P <0.05). The number of patients with nystagmus increased with the number of parachutes (P <0.01). There was a significant difference in the incidence of positional nystagmus between the number of parachutes and the number of parachutes (P <0.01). Conclusions Skydiving can impair the vestibular function and propose four indications for evaluating vestibular dysfunction caused by parachute jump
