    Application of 3D roller uniaxial rotation test in the evaluation of human vestibular stability and cardiovascular function

    •   AIM   To explore the effect of 3D roller uniaxial rotation test on the evaluation of human stability of vestibular function and cardiovascular function.
        METHODS   Twelve subjects were tested by electric swivel chair and 3D roller uniaxial rotation with leaning forward of 30° respectively. The changes of blood pressure, heart rate and heart rate variability were observed during the above processes. The vestibular stability was graded and scored according to the Vestibular Function Scale and the Graybiel Motion Sickness Scale. The failure rates were compared between the two tests.
        RESULTS   Compared with the data of pre-tests, the scores of Graybiel motion sickness increased significantly after the above two tests (P<0.05). And there was no significant difference in the failure rates of vestibular function classification between 3D roller and electric swivel chair tests. The systolic and diastolic blood pressures of the subjects were significantly elevated (P<0.05), whereas there was no significant difference in heart rates in the above two tests. What’s more, the normalized low-frequency power (LF) decreased, the normalized high-frequency power (HF) increased and LF/HF showed a decreasing trend, which did not reach a significant level.
        CONCLUSION   The application effect of 3D roller uniaxial rotation test and electric swivel chair test in the evaluation of human vestibular stability and cardiovascular function is basically the same.
