Usefulness of feedback-based techniques for the treatment of dysfunctional eating behaviors.

Clinical Eating-Related Problem	Feed-Based Technique	Number of Sessions
Food craving	HRV-BF; Beta-NF; Alpha/Theta-NF; Infraslow-NF	6 to 10
Binge eating episodes	Beta-NF	10
Regurgitation episodes	EMG-BF	3
Rumination episodes	DB-BF	n/a
Restricting behavior	Alpha-NF	10
Eating and weight concerns	HRV-BF; Alpha-NF	12–10

HRV-BF = heart rate variability biofeedback; NF = Neurofeedback; EMG-BF = electromyography biofeedback; DB-BF = diaphragmatic breathing biofeedback; n/a = not applicable.
