We evaluated the fatigue of patients with chronic fatigue syndrome by using acceleration plethysmography.
The changes in the acceleration plethysmography were relatively dominant in the sympathetic nervous system from the viewpoint of the autonomic nervous system, and the fluctuation in the time-series data of the acceleration plethysmography was decreased from the viewpoint of chaos or complexity system. We found the relation between the level of fatigue and the changes in acceleration plethysmography.
Therefore, the acceleration plethysmography might be useful for the evaluation of fatigue.
