Objective : Evaluation of autonomic nervous function using heart rate variability analysis is effective to non-invasively assess stress in real time, though the method is sensitive to body motion, making measurements difficult in patients who move during dental treatment. The purpose of this study was to determine an appropriate electrode mounting position for evaluating autonomic nervous function with body motion or suppression.
Subjects and methods : The subjects included 9 healthy volunteer adults, 7 healthy volunteer children, and 2 child patients.
1.We evaluated autonomic nervous function in the 9 adults with 5 different body motions and suppression using 6 electrode mounting positions.
2.We evaluated autonomic nervous function in the 7 volunteer children under suppression.
3.We evaluated autonomic nervous function in the 2 child patients during dental treatment by attachment of electrodes to the trunk as a trial.
Results : When the electrodes were attached to the trunk, autonomic nervous function was evaluated in over 84.0% of the attempts in the 9 adults with body motion and over 66.5% in those under suppression, while it was evaluated in 92.3% of the attempts in the 7 volunteer children under suppression, and in 90.1% and 97.7% of the attempts in the 2 child patients during dental treatment.
Conclusion : Based on our results, evaluation of autonomic nervous function for patients with body motion and suppression during dental treatment is most effective when the electrodes are attached to the trunk.
