Objective To investigate the effect of exercise bracelet on exercise therapy in patients with type 2 diabetes. Methods 100 patients with type 2 diabetes were randomly divided into two groups: observation group and control group. Both groups received routine diabetes health education and dietary exercise guidance. On this basis, the observation group used exercise bracelets for physical exercise. The blood sugar, body mass index and glycosylated hemoglobin were compared before and after intervention in two groups of patients. Results After 3 months of intervention, the body mass index, fasting blood sugar, postprandial 2H blood sugar and glycosylated hemoglobin were all lower than the control group, and the difference was statistically significant(P05). Conclusion The use of exercise bracelet can control the metabolic index of patients, improve the compliance and enthusiasm of patients, and improve the quality of life.
