【Abstract】 To assess the effect of acupoints combined with magnetism stimuli on autonomic nervous activity under a driver mental stress and fatigue using power spectral analysis of the heart rate variability(HRV) and subjective evaluation. Among the twenty six healthy males each one takes part in the A group and B group experiment. In both groups the subjects perform the driving task for 90 min under vibration conditions, and magnetism stimuli is put on the acupoints when performing the task for 1 h in A group. HRV exhibits a significant difference between the two groups after the simulated driving task( P <0.05). Acupoints combined with magnetism stimuli can reduce the mental stress and fatigue effectively.更多还原
