Polyvagal Neurofeedback: the Effects of Corpulmonale Pathway by Heart Rate Variability Biofeedback Training on Sleep Quality

Background and Aim : Background: Now a day, one of the most important social problem is the sleep disorder that more than about 40 percent of some population faced it. Biofeedback as a complementary method could reduce many of its impacts. Objective: The current study tried to show the effects of biofeedback on promotion the sleep quality and control its impacts.Methods : Methods: The 30 patients with sleep disorder include 15 were considered for the intervention and the others as the control group volunteer candidate for this study. Pittsburgh Sleep Quality Index (PSQI) used as a standard tool of sleep quality measurement for both groups. Abdominal breathing via chest breathing trained as a biofeedback (BFB) training for invention group. Heart Rate Variability (HRV) measured before and after BFB training. Data was checked for outliers and normal distribution. Data analysis was realized with Stat sigma plot. Gender distribution of sample was 55% for male and 45% for female. The average of the age was 45 years.Results : Results: Significant difference showed between two groups. Two-way ANOVA established a sleep quality promotion for invention group. In this research, variables such as the level of individual and family education, family income, and affective family environments, which can affect the dependent variables along with the experimental ones were not controlled, and this can be considered a limitation of the study.Conclusion : Biofeedback training could be use as a complementary method in sleep disorder.
