Effect of Alternate Nostril Breathing Exercise on Experimentally Induced Anxiety in Healthy Volunteers Using the Simulated Public Speaking Model: A Randomized Controlled Pilot Study

Figure 2

Comparison of the delta scores of Visual Analog Mood Scale (VAMS) factors in the test and control groups during various phases of the simulated public speaking test. The delta scores were obtained by calculating the difference between the VAMS score for each phase and the baseline score. The dark-gray line represents the test group, and the light-gray line represents the control group. The horizontal axis represents the various experimental phases, and the vertical axis represents the VAMS factor scores. The vertical bars represent the standard error. B, baseline; P, prestress; A, anticipatory phase; S, speech performance; F, poststress.
