Rajyoga meditation significantly improves heart rate variability parameters, suggesting enhanced parasympathetic tone and potential benefit in managing diabetic cardiac autonomic neuropathy.
Supports adjunctive Rajyoga meditation in diabetic autonomic neuropathy; extends RCT evidence for nonpharmacologic HRV improvement.
Background: Cardiac autonomic neuropathy (CAN) is a very common complication of Type II diabetes mellitus patients. Early detection and treatment of CAN is necessary for reduction of mortality and morbidity in type II diabetes patients.Methods: The study included 120 diagnosed cases of type 2 diabetes mellitus with autonomic neuropathy both male & female, with more than 5 years duration of disease. Age group of the study subjects was between 30 – 70 years. All the 120 diabetic subjects were assessed for their heart rate variability. These 120 diabetic subjects were further divided in two groups by sealed envelope technique, with 60 subjects in each group. Subjects in Group I (Study group) were given relaxation therapy in the form of Rajyoga meditation, as guided by Rajyoga teachers. This group was asked to continue drug therapy for type 2 diabetes mellitus as prescribed by physician. On other hand, Group II (Control group) was given drug therapy as directed by physician but without relaxation therapy. At the end of 12 weeks HRV parameters, were re-evaluated and compared between the two groups.Results: Post intervention, Heart Rate Variability results showed that mean RR interval was significantly increased, whereas mean HR was significantly decreased in group I than in group II. All Time Domain parameters (i.e SDNN, RMSSD, NN50, pNN50 & Variance) were significantly increased in group I than in group II. The Frequency Domain parameter i.e LF/HF ratio was significantly decreased in group I than in group II. Thus the results showed that Raj Yoga meditation had a beneficial effect by improving the HRV parameters in diabetic patients with autonomic neuropathy.Conclusions: The study showed there is better improvement in all parameters of HRV in group I as compared to group II with the help of simple yet effective technique of Rajyoga meditation in type II diabetes mellitus patients with cardiac autonomic neuropathy.

Verma et al. (2016) conducted an RCT in Type II diabetes mellitus with cardiac autonomic neuropathy (n=100). Rajyoga meditation vs. Routine medication only was evaluated on Mean RR interval (p=0.001). Rajyoga meditation significantly increased the mean RR interval and improved heart rate variability compared to routine medication alone in patients with type 2 diabetes and autonomic neuropathy.
