Key finding
A significant difference was observed in fasting blood glucose levels between the pretest and posttest in the experimental group (p < 0.05).
This study examined the impact of progressive relaxation exercises on fatigue and sleep issues in individuals with type 2 diabetes, revealing significant improvements in fatigue levels.

Study focus
This study examined the impact of progressive relaxation exercises on fatigue and sleep issues in individuals with type 2 diabetes, revealing significant improvements in fatigue levels.
These findings are clinically significant as they suggest that incorporating progressive relaxation exercises could be an effective strategy for managing fatigue in individuals with type 2 diabetes. This could enhance overall quality of life and potentially improve adherence to diabetes management plans.
The study's sample size may limit generalizability. The lack of significant changes in sleep quality raises questions about the intervention's effectiveness. The study did not explore long-term effects of the intervention.

Fasting plasma glucose levels decreased significantly by -34.91 mg/dL (p = 0.001).
Postprandial blood glucose levels decreased significantly by -42.36 mg/dL (p = 0.001).
Fatigue severity scores significantly decreased by -17.46 (p = 0).
Pittsburgh Sleep Quality Index scores showed no significant change (p > 0.05).
