Heart rate variability (HRV) biofeedback may reduce asthma severity and medication needs. This complementary treatment showed improvements in asthma control and pulmonary function, warranting further investigation for asthma management.

Area of Science:

  • Pulmonary Medicine
  • Psychophysiology
  • Complementary and Alternative Medicine

Background:

  • Asthma management often relies on medication, with a need for complementary therapies to improve outcomes.
  • Heart rate variability (HRV) biofeedback is a technique that trains individuals to regulate their autonomic nervous system.
  • The potential of HRV biofeedback as an adjunct treatment for asthma requires rigorous evaluation.

Purpose of the Study:

  • To assess the effectiveness of heart rate variability (HRV) biofeedback as a complementary therapy for adult asthma patients.
  • To compare HRV biofeedback with placebo biofeedback and a waiting list control group.

Main Methods:

  • Ninety-four adult asthma outpatients were recruited and stabilized on controller medication.
  • Participants were randomly assigned to four groups: full HRV biofeedback protocol, HRV biofeedback alone, placebo EEG biofeedback, or a waiting list control.

  • Asthma symptoms, peak expiratory flows, spirometry, and oscillation resistance were monitored throughout the study.

    • Main Results:

    • Both HRV biofeedback groups showed a reduction in prescribed asthma medication compared to control groups, averaging one full level decrease in asthma severity.
    • Pulmonary function, measured by forced oscillation pneumography, improved in the HRV biofeedback groups.
    • While placebo biofeedback improved asthma symptoms, it did not impact pulmonary function.

    Conclusions:

    • HRV biofeedback appears to be a beneficial complementary treatment for asthma.
    • This technique may reduce the reliance on steroid medications for asthma control.
    • Further research is recommended to validate HRV biofeedback as an asthma management strategy.
