三维滚轮训练对人体前庭功能稳定性和心血管功能的影响

目的 通过观察三维滚轮前庭功能训练后被试者心率、血压、瞳孔直径和前庭症状的变化，为建立飞行人员三维滚轮前庭功能稳定性训练方案提供实验依据。 方法 11名健康青年男性被试者利用三维滚轮前庭功能训练系统分别进行一轴向、二轴向和三轴向旋转前庭刺激训练，每轴向训练持续时间3 min，各轴向训练中间间隔（10～20）min。记录被试者训练前后血压、心率、瞳孔对光反射和前庭症状评分的变化。 结果 与训练前相比,被试者分别进行三个轴向旋转训练后，前庭症状评分显著升高（P<0.05），前庭功能稳定性分级为:0度7人，Ⅰ度3人，Ⅱ度1人，Ⅲ度0人；被试者右眼对光反射瞳孔最小直径显著降低（P<0.05）。被试者在二轴向和三轴向旋转时的心率较训练前和一轴向旋转时均显著升高（P<0.05）。 结论 利用三维滚轮前庭功能训练系统对被试者分别进行三个轴向的旋转刺激可产生适度的前庭反应，其中二轴向和三轴向旋转时的心率显著增加。本研究为飞行员三维前庭功能训练方案的制定提供了参考。

Effect of three dimensional roller vestibular function training on vestibular stability and cardiovascular function

AIM To explore the changes of heart rate, blood pressure, pupil diameter and vestibular symptoms of the subjects after vestibular function training with three-dimensional roller and to provide experimental basis for the establishment of three-dimensional roller training program of vestibular function stability for pilots. METHODS Eleven young male subjects were trained in one axial, two axial and three axial vestibular stimulation with three-dimensional roller, each axial training for 3 min. The interval time between stimulations was 10-20 min. The changes of pupil, blood pressure, heart rate and vestibular symptom score were observed before and after the training. RESULTS Compared with those pre-training, the vestibular symptom scores of subjects after each axial training were significantly higher (P<0.05). The classification of vestibular function stability (0 degree 7,Ⅰdegree 3, Ⅱ degree 1, Ⅲ degree 0) and the minimum pupil diameter of right eye decreased significantly (P<0.05). The heart rate of the subjects during the biaxial and triaxial rotation was significantly higher than that before training and during one axial rotation (P<0.05). CONCLUSION Three axial rotation stimulation produces moderate vestibular response, in which the heart rate increases significantly during the biaxial and triaxial rotation.
