Abstract
This study was conducted to observe autonomic nervous system reactions in the cardiovascular system caused by the new transcutaneous electrical nerve stimulation apparatus CONVALES®
Autonomic functions were evaluated before and after stimulation of 10 male students between 19 and 42 years of age. The dynamic observation method of autonomic functions proposed by Nishijo et al. was used for evaluating autonomic responses. The activity levels of both the sympathetic and parasympathetic systems were found to increased after stimulation. Neither significant changes in blood pressure nor adverse effects of stimulation were observed.
These results suggest that the apparatus used in this study causes autonomic responses similar to those caused by acupuncture with shallow needling during exhalation phase while sitting, or by laser acupuncture. This study also suggested that this therapeutic method is safe for short periods.
