Abstract： Objective： To observe the clinical effect of Chinese medicine fumigation combined with walking training assisted by lower-limb rehabilitation robot for muscular hypertonia after spinal cord injury. Methods：A total of 106 cases of patients with muscular hypertonia after spinal cord injury were selected and divided into the control group and the observation group according to the random number table method，with 53 cases in each group. Both groups were treated with walking training assisted by lowerlimb rehabilitation robot， and the observation group was additionally treated with Chinese medicine fumigation with Shentong Zhuyu tang based on the treatment of the control group. Both groups were treated for eight weeks. Before and after eight-week treatment，the integrated electromyography (iEMG) of lower limb muscle group， and motor function evaluated by Fugl Meyer Assessment of lower limbs (FMA- L)， Berg Balance Scale(BBS)， and 10- meter maximum walking speed test(10 mMWS) were measured，and clinical effects and incidence of adverse reactions were compared between the two groups. Results： After eight- week treatment， the total effective rates in the observation group and the control group were 94.34% and 81.13% respectively， the difference being significant(P＜0.05). After treatment， iEMG of gastrocnemius， biceps femoris， and hamstring in the two groups were decreased when compared with those before treatment， differences being significant(P＜0.01)； the above indexes in the observation group were lower than those in the control group， differences being significant(P＜0.01). Scores of FMA- L and BBS，and values of 10 mMWS in the two groups were increased when compared with those before treatment， differences being significant(P＜0.01)， and the above three indexes in the observation group were higher than those in the control group， differences being significant(P＜0.01). There was no significant difference being found in the comparison of the incidence of adverse reactions between the two groups(P＞0.05). Conclusion： Chinese medicine fumigation combined with walking training assisted by lower-limb rehabilitation robot has a defined curative effect and relatively high safety in the treatment of patients with muscular hypertonia after spinal cord injury， and can effectively improve muscular tone and motor function of lower limb muscle.
