Improvements in HRV following TFT treatment exceeded reports found in the literature at the time, with a close correspondence between improved HRV and reduced client-reported distress.
Heart rate variability is a direct readout of how well the nervous system balances stress and recovery, captured by a monitor, not a mood scale, and finding bigger improvements in HRV after tapping-based treatment than typically reported for other approaches, including in people with existing heart problems, is a striking physiological claim that deserves a closer, more rigorous look.
If these HRV gains are confirmed in controlled research, it would support using a self-administered technique as a low-cost complement to standard cardiac care, something people, including those managing existing heart conditions, could practice themselves between visits to help support their nervous system's balance.
Given the case-series nature of this early work, the clear next step is a trial using continuous wearable HRV monitoring, rather than single before/after clinic readings, in people with diagnosed heart conditions, tracking whether HRV gains from tapping sessions hold up over weeks and correspond with other cardiac markers like blood pressure or resting heart rate. It would also be worth testing whether the size of the initial HRV improvement predicts who maintains gains long-term with continued home practice.
