| 摘要: |
| 目的 观察仰姿浪木训练对线性加速度引起的晕动症的预防效果。方法 通过垂荡模拟器筛选61名晕动症敏感者，按照Graybiel评分分为轻度敏感组（Graybiel评分1～15分，n＝28）和重度敏感组（≥16分，n＝33）。两组受训者均进行连续5 d、30 min/d的仰姿浪木训练，浪木的运动频率保持在0.25～0.35 Hz、加速度保持在0.15～0.25 g。记录训练期间的Graybiel评分，并于第1、5天训练前后进行静态平衡功能测试。结果 训练期间，重度敏感组的Graybiel评分和晕动症发生率均随着训练天数的增加而下降，于训练第4天全员习服。轻度敏感组的Graybiel评分始终较低并于训练第2天全员习服。重度敏感组静态平衡功能测试中的摇摆面积在训练前后无显著变化（P＞0.05）；第1天训练后的平均速度比第1天训练前增加（P＜0.01），而第5天训练前后无明显差别（P＞0.05）。轻度敏感组的摇摆面积和平均速度在整个训练期间均无明显变化（均P＞0.05）。验证试验结果显示，两组训练后的晕动症发生率和严重程度均下降，轻度敏感组的晕动症发生率从100.00%（28/28）降至35.71%（10/28）；重度敏感组的极重度晕动症发生率从100.00%（33/33）降至6.06%（2/33），呕吐发生率从96.97%（32/33）降至6.06%（2/33）。结论 仰姿浪木训练法预防晕动症效果显著，且具有器械普及率高、操作简单等优点。 |

| Abstract: |
| Objective To observe the effect of the supine-posture ripple wood training in preventing motion sickness caused by linear acceleration. Methods Totally 61 motion sickness sensitive males were screened by a vertical oscillation simulator and divided into mildly sensitive group (Graybiel score 1-15, n＝28) and severely sensitive group (Graybiel score ≥ 16, n＝33). The participants in the 2 groups received 5-d ripple wood training, 30 min/d. The movement frequency of the ripper wood was maintained at 0.25-0.35 Hz, with an acceleration of 0.15-0.25 g. Graybiel score during the training period was recorded. The static balance function test was conducted before and after training on the 1st and 5th day. Results During the training period, the Graybiel scores and motion sickness incidence in the severely sensitive group were decreased with the increase of training days, and all participants achieved complete acclimatization on the 4th day. The Graybiel scores of the mildly sensitive group were low during the whole period, and the complete acclimatization period was 2 d. There was no significant difference in the sway area of the severely sensitive group in static balance function test before and after training (P＞0.05). The mean velocity of the severely sensitive group in static balance function test was significantly increased after training versus before training on the 1st day (P＜0.01), and there was no significant difference before and after training on the 5th day (P＞0.05). There were no significant differences in the sway area or mean velocity of the mildly sensitive group during the whole training period (all P＞0.05). The validation experiment showed that the motion sickness incidence and the symptom severity were significantly decreased in both groups; the motion sickness incidence of the mildly sensitive group decreased from 100.00% (28/28) to 35.71% (10/28); the incidence of severe symptoms in the severely sensitive group decreased from 100.00% (33/33) to 6.06% (2/33) and the vomiting incidence decreased from 96.97% (32/33) to 6.06% (2/33). Conclusion The supine-posture ripple wood training has great effect in preventing motion sickness, with widespread use and simple operation. |
