Effect of the Emotional Freedom Techniques on anger symptoms in Hwabyung patients: A comparison with the progressive muscle relaxation technique in a pilot randomized controlled trial

CONTEXT: Hwabyung is a psychosomatic disease resulting from the suppression of anger over an extended period. The Emotional Freedom Techniques (EFT) are meridian-based psychotherapy known to cure many psychosomatic diseases, and progressive muscle relaxation (PMR) is a therapeutic method that relieves physical and psychological tension by repeated tensing and relaxation of the muscles. OBJECT: In this study, we compared the effects of EFT and PMR in patients with Hwabyung. DESIGN: 40 patients were enrolled and randomized to receive 4 weeks of group sessions with either EFT (n = 20) or PMR (n = 20). Evaluations were conducted pre- and post-treatment and at 4-week and 24-week follow-ups after session end. MAIN OUTCOME MEASURES: The Hwabyung Scale, Visual Analogue Scale of Hwabyung Symptoms (VAS-HS), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), and State-Trait Anger Expression Inventory (STAXI) were administered as self-report tools. The analysis excluded 8 patients who never attended treatment and 1 patient meeting the exclusion criteria. RESULT: EFT (n = 15) and PMR (n = 16) improved Hwabyung symptoms (-13.95% and -11.46%, respectively), state anxiety (-12.57% and -12.64%, respectively), and depression (-32.11% and -18.68%, respectively) (p < 0.05 for all). Trait anger improved in EFT group (-13.4%, p = 0.004). There were no significant differences between the groups (p > 0.05) except for trait anger at post-treatment (p = 0.022 for between group). No adverse events were reported during the study.
