Abstract
To verify the effect of GSR biofeedback (GSR-BF) relaxation training on aggression, blood pressure, and blood glucose levels, we conducted a randomized controlled trial among type II diabetes patients (TIIDPs). 228 TIIDP were selected from the various hospitals of Raipur, Chhattisgarh. Sixty participants who were found to have scores above the 75th percentile on the aggression inventory were included in the sample. Participants with higher aggression were invited for intervention and out of them, 50 randomly divided into two groups: the biofeedback relaxation group and the sham-control group. The 25 TIIDPs in the treatment group were given training on the use of the GSR-BF device for the management of stress parameters, with a total of 20 sessions (30 minutes each). The 25 TIIDPs in the control group didn’t receive any training on biofeedback relaxation. Aggression, blood pressure, and blood glucose were assessed before and after the intervention. Aggression was recorded on follow-up too. The SPSS 16th version was used for the analysis. The GSR-BFgroup reported a significant change in systolic blood pressure (p = 014), blood glucose levels (P = 005) and in the dimensions of aggression (p = 001) on the post-intervention test. On the other hand, the control group reported a moderate increase in aggression. The biofeedback group had a significant reduction in the levels of aggression and blood pressure, while the control group had a significant increase in aggression. These findings will be helpful for the promotion of overall health in hyperglycemic TIIDPs.
