综合训练法预防晕船病效果评估

PREVENTION OF SEASICKNESS BY SYNTHETIC TRAINENG

目的通过对209名大学生晕船病易感性预测,对其中128名大学生进行预防晕船病训练和训练效果评估,以建立预防晕船病综合训练方案和评估方法。方法采用四柱秋千诱发试验结合个人史和心理学问卷、Graybiel晕动病评分法,进行晕船病易感性预测。根据预测结果分组训练,实验1、2组进行预防晕船病综合训练,两组训练的方法相同,但时间不一,对照组进行传统训练。训练结束后对训练效果进行陆上和海上评估。结果陆上评估显示,实验1组、实验2组训练后晕动病发病率分别为58.62%、61.54%,明显低于对照组(93.46%,P<0.01);实验1组、实验2组训练后Graybiel评分法得分分别为(4.05±4.86)、(3.88±4.26),明显低于对照组(11.37±8.28,P<0.01),耐受时间分别为(17.91±3.50)min(、18.89±2.73)min,明显高于对照组〔(15.59±5.11)min,P<0.01〕,耐受指数分别为(88.89±19.01)(、91.13±14.51)明显高于对照组(70.28±27.59,P<0.01),实验1组、实验2组Graybiel评分法分级程度重的人数构成明显低于对照组(P<0.01),表明实验1组、实验2组训练效果优于对照组。实验2组训练前后Gray-biel评分得分差值(7.83±7.97)高于实验1组(3.50±5.76,P<0.05),表明实验2组训练效果优于实验1组。海上评估显示,在3、4级海况时,实验1组Graybiel评分得分分别为(4.31±7.29、2.83±3.57),明显低于未训练组(10.50±7.52、5.95±5.74,P<0.05),说明实验1组训练可有效预防3、4级海况下的晕船病发生。结论在陆上进行综合训练法预防晕船病的效果优于传统训练法,在3、4级海况时能有效预防晕船病发生。

Objective To establish synthetic training project for preventing seasickness and evaluation method. Methods The susceptibility of seasiekness in 209 college students were predicted with fourpillar swings test, and combining with personal history, psychological questionnaire, Graybiels＇s motion sickness grade point methods. According to the predicted result, 128 participants were selectad and divided into three groups. Group 1 and 2 performed the synthetic training to prevent seasickness. Participants in Group 1 were continually trained for 1 h per day or every other day for 14 times, and in Group 2 for 28 times. Participants in the control group were trained by traditional training for 28 times. After training the results were evaluated on the land and at sea respectively. Results Evaluation on land showed that the incidences of motionsickness in Group 1 （58.62%） and Group 2 （61.54%） were significantly lower than in control group （93.46 %, P 〈 0.01 ）. Graybiel＇ s points in Group 1 （4.05 ± 4.86） and Group 2 （3.88 ± 4.26） were significandy lower than in control group （ 11.37 ± 8.28, P 〈 0.01 ）. Tolerance - time, and tolerating - index in Group 1 [（17.91 ± 3.50）min, 88.89±19.01] and Group 2[（18.89 ± 2.73）min,91.13 ± 14.51] were higher than in control group[ （ 15.59 ± 5.11 ） min, 70.28±27.59, P 〈 0.01]. The proportion of severe motionsickness by Graybiel＇ s grade in Group 1 and Group 2 was lower than in control group（P 〈 0.01 ）, indicating that the training effect of Group 1 and Group 2 were better than control group. The difference of Gabriel＇ s grade point between pre and post training in Group 2 （7.83 ± 7.97） was higher than in Group 1 （3.50 ± 5.76, P 〈 0.05 ）, indicating that the training effect of Group 2 was better than Group 1. Evaluation at sea Graybiel＇ s grade point under 3,4 class sea conditions in Group 1 （4.31 ± 7.29,2.83± 3.57） were lower than untraining group （10.50±7.52,5.95 ±5.74）（ P 〈0.05）, indicating that training for Group 1 could prevent from seasickness oeeurrence effectively under 3,4 degree sea conditions. Conclusion Synthetic training method on land can prevent seasickness better than traditional training method and can prevent from seasickness occurrence effectively under 3,4 class sea conditions.
