<![CDATA[Background: Diabetes mellitus is a chronic metabolic disease characterized by high blood sugar levels. Indonesia ranks fifth globally in the number of people living with diabetes. If the condition is not well controlled, it increases the risk of diabetes-related deaths. One of the five diabetes control programs is physical exercise, including progressive muscle relaxation therapy, which involves gradually tensing and relaxing muscles to promote physical relaxation. Methods: This study used a quasi-experimental design with pretest-posttest and control groups. A total of 62 respondents were selected through simple random sampling using the Spiner website and divided into two equal groups of 31 each. The research instrument was a glucometer, and a daily checklist questionnaire completed by the researcher evaluated the participants' exercise and medication adherence. Data were analyzed using paired t-tests and independent t-tests. Result: The study found a significant reduction in blood sugar levels in the experimental group that performed progressive muscle relaxation therapy via video. The average decrease was 12.45 mg/dL, with a p-value of 0.000, indicating a strong effect. Conclusion: Progressive muscle relaxation therapy delivered through video effectively lowers blood sugar levels in patients with type 2 diabetes mellitus. This therapy is recommended as a routine exercise method to help control blood sugar levels in diabetic patients.]]>
