Heart rate changes associated with biofeedback training

The present study compared the heart ratechanges associated with two most commonlyused biofeedback relaxation techniques in thetreatment of Generalized Anxiety Disorder(GAD). 45 individuals with GAD (as defined byDSM-IV TR) were randomly assigned to threegroups: Group I (n = 15) received EMGbiofeedback relaxation training; Group II (n =15) received alpha–EEG biofeedbackrelaxation training and Group III (n=15) controlgroup. Both EMG and EEG groups resulted inmore consistent pattern of generalizedrelaxation changes reflected in heart rate ascompared to control group. At follow-up,maintenance of effects was not observed inboth treatment groups.
