Abstract： Objective： To observe the clinical effect of the therapy of modified Buyang Huanwu tang combined with rehabilitation training on stroke complicated with hemiplegia. Methods：A total of 100 stroke patients complicated with hemiplegia were divided into the control group and the observation group according to the random number table method，with 50 cases in each group. The control group was treated with routine rehabilitation training and the observation group was additionally treated with modified Buyang Huanwu tang based on the treatment of the control group. The clinical effects in the two groups were evaluated. The motor function and limb sensory function were evaluated by the scores of motor function and limb sensory function in Fugl-Meyer Scale，Ability of Daily Living by Barthel Index，and cognitive function by Loewenstein Occupational Therapy Cognitive Assessment(LOTCA). Before and after treatment， the blood viscosity was detected. Results： The total effective rate was 82.00% in the observation group， higher than that of 62.00% in the control group， the difference being significant(P＜0.05). Before treatment，there was no significant difference being found in the comparisons of scores of Fugl- Meyer， Barthel Index and LOTCA between the two groups(P＞0.05). After treatment，the scores of Fugl-Meyer， Barthel Index and LOTCA in the two groups were increased when compared with those before treatment (P＜0.05)，and the above three scores in the observation group were higher than those in the control group (P＜0.05). Before treatment，there was no significant difference being found in the comparisons of whole blood viscosity and plasma viscosity between the two groups(P＞0.05). After treatment， the levels of whole blood viscosity and plasma viscosity were decreased when compared with those in the control group (P＜0.05)，and the above two levels in the observation group were lower than those in the control group(P＜ 0.05). Conclusion：The therapy of modified Buyang Huanwu tang combined with rehabilitation training has a good curative effect on stroke patients complicated with hemiplegia， which can improve the sensibility， motor ability and ability of daily living，enhance the cognitive function，and reduce the blood viscosity.
