Abstract： Objective： To observe the effect of Poyu Xingshen Decoction combined with balanced muscular tension needling method on muscle strength，limb function and self-care ability in patients with hemiplegia caused by cerebral infarction. Methods： A total of 94 patients with hemiplegia caused by cerebral infarction were numbered in the order of admission and divided into the control group and the observation group according to the random number table method， with 47 patients in each group. Both groups were given basic treatment and balanced muscular tension needling method，and the observation group was additionally treated with Poyu Xingshen Decoction. Both groups were treated for 30 days. The clinical effects and adverse reactions were compared between two groups. The traditional Chinese medicine (TCM) syndrome scores， muscle strength， muscle tension， limb function， and self- care ability were compared between the two groups before and after treatment. Results： After treatment， the total effective rate was 87.23% in the observation group，higher than that of 68.09% in the control group (P＜ 0.05). After treatment， the scores of TCM syndromes including hemiplegia， deviation of the tongue and mouth，difficulty or silence in speech，loss or disappearance of sensation，dizziness，and excessive and sticky phlegm， as well as the total scores were decreased (P＜0.05)， and the scores in the observation group were lower than those in the control group (P＜0.05). After treatment， the Ashworth scores of muscle strength were decreased (P＜0.05) in the two groups，and the scores of Lovett muscle strength， Fugl Meyer Scale， and Modified Barthel Index (MBI) were increased (P＜0.05)； the Ashworth score of muscle strength in the observation group was lower than that in the control group (P＜0.05)，and the scores of Lovett muscle strength，Fugl Meyer Scale，and MBI were higher than those in the control group (P＜ 0.05). After treatment， the average electromyographic value (aEMG)， integral electromyographic value (iEMG)，and peak value in the two groups were increased (P＜0.05)，and the indexes in the observation group were higher than those in the control group (P＜0.05). After treatment，the levels of brain- derived neurotrophic factor (BDNF) and γ- aminobutyric acid (GABA) were increased (P＜0.05)， and the levels in observation group were higher than those in the control group (P＜0.05). Conclusion： Poyu Xingshen Decoction combined with balanced muscular tension needling method has a good effect on treating hemiplegia caused by cerebral infarction，which is beneficial for promoting symptom relief and neurological function recovery， enhancing muscle strength and inhibiting muscle tension， improving limb motor function，and enhancing the self-care ability of patients.
