| 目的 研究正弦垂荡刺激、视觉虚拟现实（VR）涌浪刺激和两者联合刺激条件下的防晕动症习服时间和习服效果。方法 通过海上实航6 h筛选120名极重度晕动症者，随机分为4组（n＝30）：垂荡训练组、VR训练组、垂荡＋VR训练组和对照训练组。采用Graybiel量表评估训练期间每日的症状严重程度，记录VR训练组的弹性踏台掉落次数，以连续3 d Graybiel评分为0分和/或弹性踏台掉落次数为0次判定为完全习服。采用比筛选时更恶劣海况条件下的海上实航验证训练效果。结果 垂荡训练组、垂荡＋VR训练组的Graybiel评分及VR训练组的弹性踏台掉落次数均随着训练天数的增加而下降，并分别于训练第3天、第5天和第2天达到习服水平。垂荡训练组、垂荡＋VR训练组、VR训练组的最长习服时间分别为8、8、5 d，平均习服时间分别为3.6、3.9、2.7 d，5 d习服率分别为93.33%（28/30）、76.67%（23/30）、100.00%（30/30），海上实航验证期间习服训练有效人数占比分别为86.67%（26/30）、96.67%（29/30）、66.67%（20/30），训练有效率分别为85.19%、96.30%、62.97%。结论 3种训练方法均有明确的防晕动症习服训练效果，且习服时间仅为5～8 d。垂荡和垂荡＋VR训练的习服效果优于VR训练。 |

| Abstract: |
| Objective To study the acclimatization time and effects for preventing motion sickness under sinusoidal vertical oscillation stimulation, visual virtual reality (VR) swell stimulation, and their combined stimulation. Methods Totally 120 individuals with extremely severe motion sickness during 6 h navigation were randomly divided into 4 groups (n＝30): vertical group, VR group, vertical＋VR group, and control group. The severity of symptoms during the training period was assessed daily by Graybiel scale, and the number of drops from flexible treadmill in the VR group was recorded. The Graybiel score of 0 for 3 d and/or the number of drops for 0 were considered as complete acclimatization. The training effect was validated by navigation under more severe sea conditions. Results The Graybiel scores of the vertical group and vertical＋VR group, as well as the number of drops of the VR group were decreased with the increase of training days, and reached the acclimatization level on the 3rd, 5th, and 2nd training day, respectively. The longest acclimatization time in the vertical, vertical＋VR, and VR groups was 8, 8, and 5 d, with an average acclimatization time of 3.6, 3.9, and 2.7 d, respectively; the acclimatization rates within 5 d were 93.33% (28/30), 76.67% (23/30), and 100.00% (30/30), respectively; the proportions of individuals with effective acclimatization training in the verification voyage were 86.67% (26/30), 96.67% (29/30), and 66.67% (20/30), respectively; and the training efficiency was 85.19%, 96.30%, and 62.97%, respectively. Conclusion Three training methods all have effects on motion sickness acclimatization, and the acclimatization period is 5-8 d. The acclimatization effects of the vertical oscillation and vertical oscillation＋VR training are better than the VR training. |
