Preliminary Study of Applying Acupoints Combined with Magnetism Stimuli to Reduce Driver Postural Fatigue

In designing an automobile seat, it is important to minimize the fatigue experienced by the driver resulting from long-term sitting. In this study eight healthy male subjects participated in two group experiments that were A-group and B-group. Acupoints combined with magnetism stimuli were put on to the subjects for reducing postural fatigue in B-group during the simulated driving. The surface electromyography (sEMG) of muscle activity at L4/L5 as well as subjective self-reporting on fatigue were recorded and tested. Analyzing and comparing the EMG median frequency and the subjective evaluations between two groups a conclusion that acupoints combined with magnetism stimuli could reduce the driver postural fatigue was drawn.
