Changes in finger temperature and blood flow in response to different frequencies of transcutaneous electroacupuncture at LI4 (hegu)
Background. Finger blood flow and temperature are often used as indices of autonomic (sympathetic) function. Transcutaneous electroacupuncture (TEA) is an increasingly used variant of electroacupuncture (EA). This is the fifth in a series of conference posters from a study investigating the effects of EA and TEA on heart/pulse rate variability (HRV/PRV), the electroencephalograph (EEG), and now blood flow.
