Using heart rate variability analysis to assess the effect of music therapy on anxiety reduction of patients

Music therapy has been considered to reduce the anxiety of patients, but the mechanism of music therapy remains to be investigated. Psychophysiological researchers have revealed that the autonomic activities relate to the anxiety. Heart rate variability (HRV) analysis has been used to assess the autonomic activities hence it may be a useful tool for evaluate the effects of music therapy on anxiety reduction of patients. In this study, we...
