Effects of single-point acupuncture (HT7) in the prevention of test anxiety: Results of a RCT - Fig 2

Describes the physiological and psychological effects of acupuncture on test anxiety, i.e. the time-course of (A) saliva cortisol and (B) saliva amylase. (C) and (D) depict the ECG analysis with respect to heart rate and heart rate variability. (D) is the score of the MDMF and (F) the scores of the STAI-state anxiety. The red flashes labelled TSST indicate the occurrence of the stress test, the acupuncture needle depicts the time of intervention (30 minutes prior to the TSST). The times are as follows: -40 and -10 minutes previous to the TSST, and +10, +20, +30, +40, +55, +70 minutes thereafter (as suggested by Kirschbaum et al., 1993).
