Diabetes mellitus is a complex, chronic disease that requires continuous medical care with multifactorial, risk-reducing strategies beyond glycemic control. This study aimed to determine the effect of Buerder Allen Exercise on the circulation of the lower extremities in patients with type II diabetes mellitus. This research used Quasi-Experimental Design with a Pretest-Posttest approach with an experiment and control group. Research place in Kuningan, West Java, Indonesia. Respondents in this study were patients with diabetes mellitus totaling 42 respondents, which were divided into 21 intervention (experimental) groups and 21 control groups. Sampling using purposive sampling. The instruments used were Vascular Doppler and sphygmomanometer. Bivariate data analysis used is the Wilcoxon test. The results showed that the average pretest and post-test ABI values in the intervention group were 0.00 and 11.00, while in the control group, the averages were 11.00 and 0.00. Based on the results of the Wilcoxon test, a p-value of 0.000 (α 0.05) means that there is an effect of Buerder Allen exercise on the circulation of the lower extremities in patients with type II diabetes mellitus. Buerder Allen exercise positively impacts the circulation of the lower extremities in patients with diabetes mellitus.
