The purpose of this article was to systematically review the literature on the effects of biofeedback therapy on anger. Biofeedback methods are shown to be effective in the treatment of a number of health conditions; however, a systematic review of biofeedback therapies on anger management has yet to be conducted. Results of the literature review show that little attention was given to anger over the years in comparison to other health and emotional conditions. Research is needed to determine whether biofeedback is an efficacious treatment for emotional regulation.
