Key result
Heart rate variability biofeedback combined with intero-nociceptive emotion exposure therapy significantly decreased resting heart rate by 3.4 bpm from the first to the last therapeutic session.
Why the study?
Psychiatric patients with adverse childhood experiences often have dysfunctional interoceptive emotional regulation, and heart rate variability may serve as a real-time feedback measure for sympathovagal balance.
Does heart rate variability biofeedback during emotion exposure therapy improve autonomic balance in outpatients with adverse childhood experiences?
Observational (n=100)
No
Does heart rate variability biofeedback during emotion exposure therapy improve autonomic balance in outpatients with adverse childhood experiences?
HRV biofeedback during emotion exposure therapy for adverse childhood experiences may improve autonomic balance by decreasing heart rate and increasing HRV.

May support autonomic benefits in adverse childhood experiences; leaves open confirmation in randomized trials.
<ns3:p> <ns3:bold>Background</ns3:bold> : Psychiatric patients with adverse childhood experiences (ACE) tend to be dysfunctional in the interoceptive part of their emotional experience. The integration of interoceptive emotional activity in the insular and cingulate cortices is linked to the regulation of sympathovagal balance. This makes heart rate variability (HRV) an ideal measure for providing feedback on emotion regulation in real time. </ns3:p> <ns3:p> <ns3:bold>Methods</ns3:bold> : A sample of one hundred (n=100) outpatients was evaluated. Participants underwent eight 30-minutes ACE exposure sessions during which patients were guided to experience bodily sensations related to ACE while their HRV was monitored using a commercial biofeedback device. </ns3:p> <ns3:p> <ns3:bold>Results</ns3:bold> : Comparing the results of first to last therapeutic session, a significant decrease in heart rate and an increase in HRV at the onset of the session were observed. </ns3:p> <ns3:p> <ns3:bold>Conclusions</ns3:bold> : This study suggests physiological impact of therapeutic interventions on the autonomic balance and underlines the interest of HRV biofeedback as a clinical practice. </ns3:p>

Hahusseau et al. (2020) conducted an observational in Adverse childhood experiences (ACE) (n=100). Heart rate variability biofeedback intero-nociceptive emotion exposure therapy was evaluated on Change in heart rate between session 1 and session 2 (p=0.029). Heart rate variability biofeedback combined with intero-nociceptive emotion exposure therapy significantly decreased resting heart rate by 3.4 bpm from the first to the last therapeutic session.
