Research progress of electroacupuncture against orthostatic intolerance of post-spaceflight

Factors such as environmental change during space flight have the widespread influences on physical and mental health, causing aerospace medical problems like cardiovascular dysfunction. One of its manifestations of cardiovascular disorders is orthostatic intolerance. At present, these measures to protect against the physiological effects of weightlessness provide a protective effect, but still cannot completely eliminate the adverse effects of weightlessness on cardiovascular system. Therefore, it is very necessary to find a convenient and effective protective countermeasures. Clinical practice and modern experimental research have revealed that acupuncture and moxibustion has very good regulating effect on cardiovascular system. However, until now, there is no unified stimulus standard (such as stimulus frequency, time etc), which seriously affects the repeatability of operation and the efficacy of acupuncture. Therefore it's very important to set a repeatable standard.
