Research progress of electroacupuncture against orthostatic intolerance of postspaceflight 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 itu0027s very important to set a repeatable standard

Using Virtual Reality to Examine the Correlation between Balance Function and Anxiety in Stance We study the interaction between balance function and anxiety in humans via a virtual reality based experimental setup, fundamentally designed to examine postural control and neurological feedback during balancedemanding height and perturbation shifts, while in quiet stance. In this work, sensory organization balance test (SOT) was utilized to quantify the balance function in subjects, and the salient features of the recorded electrocardiogram (EKG), electromyogram (EMG) and electroencephalography (EEG) signals described the subjectu0027s physiological anxietyrelated responses. Also, patientreported outcomes measurement information system (PROMIS) trait anxiety questionnaire was adopted to indicate the selfassessed trait anxiety scores by the subjects. Our statistical analysis indicates that subjects with higher SOT scores encounter a lower heart rate variability during baseline recording relative to the experimental trials and lower cocontraction index of the ankle dorsiflexion (during the experimental trials), suggesting a lower anxiety state. A similar trend was further observed via the selfreported PROMIS questionnaire responses, estimating anxiety experienced in daily life. Additionally, we utilize machine learning to describe the predictability of balance function states via the relative  alpha band power from the frontal channels of the recorded EEG signals as descriptive features characterizing anxiety. The discussed trends analytically demonstrate the potential for adopting balance function to anticipate anxiety, especially in stressful environments involving postural threats.
