Abstract:
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.
