Efectividad del entrenamiento de biorretroalimentación de la variabilidad de la frecuencia cardíaca: ensayo controlado aleatorizado

Abstract

Introduction: Heart rate variability (HRV) biofeedback is one of the most promising techniques for managing symptoms of anxiety, stress, and other psychophysiological disorders. Objective: To analyze the effectiveness of a personalized biofeedback protocol in reducing symptoms associated with depression, anxiety, and stress by randomly assigning participants to three conditions: Biofeedback training, Biofeedback training with home practice, and Control. Method: A study was conducted with a randomized controlled design with a sample of 113 university students. Results: A significant decrease in stress [F = 9,88, p = <0,01, η2 = 0,18], anxiety [F = 10,43, p = <0,01, η2 = 0,21], and depression levels [F = 8,20, p = <0,01, η2 = 0,15] was identified in both experimental groups. Conclusions: HRV biofeedback training significantly decreases stress, anxiety, and depression levels. Participants who received biofeedback training with home practice reported the best results.
