【摘要】：目的通过对前庭训练中各项生理指标变化观察检验前庭刺激是否适当 ,评价前庭训练在提高人体前庭功能适应性方面的作用 ,以便于在前庭训练中把握训练量 ,制定和实施训练计划。方法对 1 0名健康被试者 ,在不同日期分别进行了线性加速度刺激、连续的科氏加速度累积刺激和间断的科氏累积加速度刺激 ,刺激的终止指标以被试者感觉有轻度植物神经症状为准。在实验中对被试者在刺激前后前庭 -植物神经反应、心电、血压、胃电以及动态姿态平衡等各项生理指标进行了测试。结果 1 0名被试者中有 1人 3项前庭刺激达到达标水平 ,他在实验中有轻度运动病症状。实验前后动态姿态平衡的测试表明 ,对于大多数被试者 ,线性加速度刺激后 ,前庭觉在维持身体平衡时作用增高 ;连续的科氏累积加速度刺激后前庭觉在维持身体平衡时作用下降 ;间断的累积加速度刺激训练 ,由于刺激相对较重 ,在动态平衡测试中 ,前庭感觉分在刺激后的变化个体差异较大。线性加速度刺激后 ,感觉综合测试 (SOT)第2项平衡分显著下降 ,间断科氏加速度刺激后 ,此项平衡分显著升高。结论本实验所设计的前庭刺激训练方法是可行的 ,训练负荷是可以达到的。通过胃电、血压和心电R R功谱低频谱百分比的变化可以反映被试者前庭刺激终止时的生理状态 ,为制定前庭
[Abstract]:Objective to evaluate the function of vestibular training in improving the adaptability of human vestibular function by observing the changes of physiological indexes in vestibular training, and to evaluate the function of vestibular training in order to grasp the amount of training in vestibular training. Develop and implement training plans. Methods 10 healthy subjects were subjected to linear acceleration stimulation, continuous Coriolis acceleration cumulative stimulation and intermittent Coriolis cumulative acceleration stimulation on different days. The termination of stimulation was determined by mild autonomic symptoms. The vestibule-vegetative nerve response, electrocardiogram, blood pressure, gastric electricity and dynamic posture balance were measured before and after stimulation. Results one out of 10 subjects had 3 vestibular stimuli to reach the standard level, and he had mild motor disease symptoms in the experiment. The dynamic posture balance test before and after the experiment showed that the vestibular sensation increased after linear acceleration stimulation in maintaining the balance of the body for most of the subjects. After continuous Coriolis cumulative acceleration stimulation, the vestibular sensation decreased in maintaining the body balance; the intermittent cumulative acceleration stimulation training, due to the relatively heavy stimulus, was used in the dynamic balance test. The vestibular sensory scores varied greatly after stimulation. After linear acceleration stimulation, the second equilibrium score of sensory synthesis test (SOT) decreased significantly, and the balance score increased significantly after intermittent Coriolis acceleration stimulation. Conclusion the vestibular stimulation training method designed in this experiment is feasible and the training load can be achieved. The changes of electrogastrogram, blood pressure and the percentage of low spectrum of R R work spectrum of ECG can reflect the physiological state of the subjects at the end of vestibular stimulation.
