To explore the clinical effect of Buyang Huanwu decoction in the treatment of stroke, and to analyze the improvement of neurologic impairment and the influence on hemorheology. Methods:A total of 200 cases of stroke patients who were treated in our hospital from February 2014 to September 2016, and were randomly divided into control group and treatment group, with 100 cases in each group. The control group was treated with conventional western medicine treatment, and treatment group was treated combined with Buyang Huanwu decoction based on the control group, with 4 weeks as 1 treatment course. Both groups were treated for 2 courses continuously. The clinical efficacy of 2 groups was evaluated, and the NHISS score and Barthel score were determined and compared. The disabling conditions of 2 groups were compared. Besides, the hemorheology indexes before and after treatment was detected and compared. Results:The clinical total effective rate (9400%) in treatment group was higher than the control group (6700%) (P<001). Compared with before treatment, the NIHSS scores of 2 groups decreased significantly, and the treatment group was lower than that of control group (P<005). The Barthel scores of 2 groups increased significantly, and the treatment group was higher than that of control group (P<005). Compared with that before treatment, the proportion of 0, 1, 2 class disabled patients in 2 groups increased significantly (P<005 or P<001), while the proportion of 4 class disabled patients in 2 groups and the proportion of 5 class disabled patients in treatment group decreased significantly (P<005 or P<001). The proportion of disability level
