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.
