To observe the clinical effect of acupuncture combined with Jiejing Decoction（解痉汤）in the treatment of upper limb muscle tension after stroke.

Eighty-four patients with increased upper limb muscle tension after stroke diagnosed and treated in the hospital from June 2021 to December 2022 were selected as the research objects. According to the random number table method，they were randomly divided into two groups，with 42 cases in each group. The control group was treated with Jiejing Decoction and the observation group was treated with acupuncture combined with Jiejing Decoction for 4 weeks. The total effective rate，muscle tension，upper limb motor function and daily living ability of the two groups were observed and compared. The curative effect was judged by the change of TCM symptom scores，the muscle tension was evaluated by modified Ashworth grading standard，the upper limb motor function was evaluated by Fugl-Meyer motor score（FMA），and the daily living ability was evaluated by Barthel index.

The total effective rate of the observation group was 97.62%（41/42），significantly higher than that（80.95%，34/42）of the control group，and the difference between two groups was statistically significant（P<0.05）. There was no statistically significant difference in muscle tone grading between the two groups before treatment（P>0.05），but after treatment，the observation group was significantly better than the control group，and the difference was statistically significant（P<0.05）. There was no significant difference in the H/M ratio of the radial nerve，ulnar nerve or median nerve reflection wave between the two groups before treatment（P>0.05）. After treatment，the H/M ratio of the radial nerve，ulnar nerve and median nerve reflection wave in the observation group was significantly lower than that in the control group，and the difference was statistically significant（P<0.05）. After treatment，the FMA score and Barthel index score of the two groups were significantly increased，and the scores of the observation group were significantly higher than those of the control group（P<0.05）. No serious adverse reactions occurred in both groups.

The clinical efficacy of acupuncture combined with Jiejing Decoction in the treatment of upper limb muscle tension after stroke is satisfactory. It can significantly improve the upper limb muscle tension，and improve the upper limb motor function and daily living ability of the patients，and it has good safety.
