Key result
In a trial of 15 students, HRV biofeedback treatment significantly reduced trait anxiety compared to no treatment, whereas relaxation training showed no significant difference.

Does heart rate variability biofeedback treatment or relaxation training reduce trait anxiety in graduate students with moderate trait anxiety?
Heart rate variability biofeedback treatment demonstrates potential benefits in reducing trait anxiety compared to no treatment among graduate students.
Lee et al. (2015) conducted an RCT in Trait anxiety (n=15). Heart rate variability (HRV) biofeedback treatment vs. Relaxation training and no treatment control was evaluated on Change score of trait anxiety. In a trial of 15 students, HRV biofeedback treatment significantly reduced trait anxiety compared to no treatment, whereas relaxation training showed no significant difference.
