TY - JOUR AU - Hong, Harry PY - 2019 DA - 2019/03/25 TI - <b>Increase in Electrodermal Activity on Acupuncture Points of Lymphatic, Lung, Nervous, Endocrine and Heart Meridians after Running Exercise, a Single Case Study</b> JO - OBM Integrative and Complementary Medicine SP - 019 VL - 04 IS - 01 AB - Background: Electrodermal measurement of acupuncture points has been correlated to physiologic and pathologic conditions with clinical and laboratory studies. Emerging evidence indicates that in addition to therapeutic effect, acupuncture points may also have diagnostic properties. However, physiologic basis of this phenomenon is still unknown. Objective: To determine how electrodermal activity of acupuncture points on hands and feet responds to exercise-induced sympathetic stress and how electrodermal measurement correlates to skin temperature. Materials and Methods: A 20-minute running exercise with a moderate intensity based on Borg Rating of Perceived Exertion Scale was carried out with one healthy male subject for 15 sessions. Electrodermal activity of acupuncture points was tested before and after exercise with a meridian testing system, Electroacupuncture According to Voll. Bio signs including heart rate, breathing rate, blood oxygen level and skin temperature for forehead, hands and feet were also measured. Result: Significant increase in electrodermal activity for five hand meridians, including Lymphatic, Lung, Nervous system, Endocrine systems and Heart, was observed after exercise. There was no significant change for the rest of hand meridians and foot meridians. Significant increase in foot skin temperature and decrease in hand and forehead temperature were also observed after exercise. The change in skin temperature for hand and foot was inversely related to that of electrodermal measures. Conclusion: Despite the limitations, the finding of the study is consistent with expected physiologic responses to the stress due to running exercise and it is feasible to conduct clinical studies with larger sample size to further study the change of electrodermal activity of acupuncture points after exercise. It also suggests that electrodermal testing of acupuncture points may be useful to detect stresses from corresponding organs and tissues. More clinical and mechanistic studies are warranted.
