Online published on 18 April, 2019. Abstract Background/Objectives The present study aimed to investigate the effects of dual-task training with different intensity of aerobic exercise on cognitive function (MMSE-K, Trail making test, and Stroop test) and neurotrophic factors (BDNF, IGF-1) in chronic stroke patients. Methods/Statistical analysis The subjects were 27 stroke patients who met the study selection criteria, and were divided according to screening tests into the following: group I (low-intensity aerobic exercise plus dual-task training, n=9), group II (moderate-intensity aerobic exercise plus dual-task training, n=9), and group III (high-moderate-intensity aerobic exercise plus dual-task training, n=9). Subjects performed training 5 times a week, a total of 30 times in 6 weeks. Finding The results of the study showed that moderate-intensity aerobic exercise (p<.01) and high-intensity aerobic exercise (p<.001) showed significant differences between after training (p<.001). Significant differences between the groups were found after training, with a difference in MMSE-K between group I and III (p<.001) and between group II and III (p<.01). A significant difference was found between the groups in the Trail Making Test and the Stroop test (p<.001), with a difference after training between group I and III (p<.001) and between group II and III (p<.01). In addition, a significant difference was found between the groups in BDNF and IGF-1 levels (p<.001), with a difference between group I and III (p<.001) and between group II and III (p<.05). Improvements/Applications Therefore, the present study found that the effectiveness of cognitive rehabilitation for stroke patients can be enhanced by using differentiated aerobic exercise rather than limited desktop activity Top Keywords Dual task training, Aerobic exercise, Intensity, Cognitive function, Neurotrophic factor.
