Title : Yoga based relaxation techniques improves cardiac autonomicdysfunction in patients with type 2 Diabetes Mellitus

Abstract

Background: Cardiac autonomic dysfunction is a well recognized complication of Type 2 Diabetes Mellitus (T2DM).Two methods of Yoga based relaxation technique(Deep relaxation technique and slow breathing exercise) enhanced  autonomic balance  in adult healthy volunteers. 
Objective: This study aimed  to evaluate the impact of Deep relaxation technique(DRT) and slow breathing exercise(SBE)  on cardiac autonomic nerve function by analysis of Heart Rate Variability (HRV) in T2DM patients. Methods: This Quasi experimental study was conducted on 30 female  and 30 male  T2DM patients aged 50-55 years with duration of diabetes of 5-10 years; Female patients performed DRT and male patients SBE (20 minutes twice daily) for 3 months. Thirty apparently healthy female and 30 male with similar age without any kind of exercise were control. To assess the cardiac autonomic nerve function, HRV data were recorded by a data acquisition device Power Lab (Australia). HRV data of all subjects were collected at baseline  and also after 3 months of intervention or follow-up. For statistical analysis, paired sample t test and independent sample t-test were used. Results: Most of the baseline values of HRV in T2DM was significantly lower (p<0.001) compared to control. After 3 months of DRT and SBE, there was significant improvement in most of the HRV measures in patients. There were either non significant changes or further deteriorated HRV in patients without intervention with relaxation technique after 3 months of follow up Conclusion: DRT and SBE effectively improved cardiac autonomic dysfunction in T2DM with increment in parasympathetic and decrement in sympathetic activity and parasympathetic dominance autonomic balance.
Keywords: Deep relaxation technique, slow breathing exercise Autonomic nerve function, Heart rate variability, type 2 Diabetes mellitus.
