Background: Nowadays, one of the most important social troubles is the sleep disorder that more than 40% of some population faced. Biofeedback (BFB) as a complementary method could reduce many of its effects.Objectives: This study aims to show the effects of BFB on the promotion of sleep quality and control sleep disorder impacts. Methods: An interventional study was conducted on 48 volunteer patients with sleep disorders. Twelve patients were included in each of four groups consisting of control. Pittsburgh Sleep Quality Index (PSQI) was used as a standard tool for sleep quality measurement in both groups. Abdominal breathing via chest breathing was trained as a BFB training exercise for patients. Heart rate variability (HRV) was measured before and after BFB training. Data were checked for outliers and normal distribution. SPSS version 22 and a diagram prepared by sigma plot version 14 did data analysis. Results: The finding showed the promotion of sleep quality by pulse regulated abdominal breathing (PRAB) by a significant difference before and after BFB for four weeks. Conclusion: Based on the finding of this study, polyvagal BFB training was utilized as a complementary method for HRV thus not only can it treat the patients with a sleep disorder but also promote sleep quality of the normal persons. Hence, the PRAB can be used for the patients with chief complain of sleep disorder.
