Thought Field Therapy (TFT) is one of several unusual psychotherapies that have witnessed rapid growth over the past few years, despite the absence of scientific support. Promoters of TFT frequently cite changes in heart rate variability (HRV) as evidence of TFT's effects. Pignotti and Steinberg (2001) present reports of 39 cases in which HRV was assessed prior to and immediately following TFT. Serious methodological shortcomings preclude interpretation of these data with respect to either the efficacy of TFT or the clinical utility of HRV. Ethical concerns are raised about the aggressive promotion of TFT and the misuse of HRV.
