| Outline of Final Research Achievements |
To date, we have reported that phasic electrical stimulation during expiration (PESE) in the rehabilitation of patients with chronic obstructive pulmonary disease (COPD) improves ventilation efficiency. In this study, our aim was to elucidate the mechanism of action of PESE for its clinical application, and to identify the optimum site for stimulation. In addition, we examined the effect of dynamic hyperinflation, which is a cause of shortness of breath. From the results of this study, it became evident that the mechanism by which ventilation efficiency improves is the effect of awareness due to PESE. Moreover, the potential of the forearm to be readily exposed makes it a good site for stimulation. On the other hand, we found that PESE does not improve inspiratory capacity, which is an index of dynamic hyperinflation.
