To explore the effect of acupuncture combined with Gualou Guizhi Decoction on spasticity of elbow flexion and EMG integral of upper limbs after stroke. Methods:A total of 116 patients with upper extremity elbow flexion spasm after stroke were enrolled in Yan'an University Affiliated Hospital from November 2016 to January 2019. They were randomly divided into a control group (58 cases) and an observation group (58 cases). The control group received routine rehabilitation training and oral baclofen tablets. The observation group was treated with acupuncture and moxibustion combined with Gualou Guizhi Decoction on the basis of the control group for 4 weeks. The clinical spasm index (CSI), modified Barthel index (MBI), modified Ashworth scale (MAS), simple Fugl-meyer motor scale (FMA), EMG integral value, EMG F wave and quality of life were observed and compared before and after treatment in the 2 groups. Results:1)After treatment, CSI and MAS in the 2 groups decreased significantly, and MBI and FMA increased significantly (P<0.05). MBI and FMA in the observation group were significantly higher than those in the control group, and CSI and MAS were significantly lower than those in the control group (P<0.05). 2) After treatment, biceps brachii, flexor carpi ulnaris and deltoid muscles decreased significantly in both groups, while triceps brachii increased significantly (P<0.05). After treatment, triceps brachii in the observation group was significantly higher than that in the control group, and the rest were significantly lower than that in the control group (P<0.05). 3) After treatment, the F wave amplitude of EMG in both groups decreased significantly, and the threshold value increased significantly (P<0.05). After treatment, the threshold value in the observation group was significantly higher than that in the control group, and the amplitude was significantly lower than that in the control group (P<0.05). 4) After the completion of treatment, the energy impact, family role, language function, activity ability, emotional impact and self-care ability of the 2 groups were significantly increased than those before treatment (P<0.05), and the above indicators in the observation group were significantly higher than those in the control group (P<0.05). After the completion of treatment, the marked efficiency and total efficiency of the observation group were significantly higher than those of the control group, and the difference was statistically significant (P<0.05). Conclusion:Acupuncture and moxibustion combined with Gualou Guizhi Decoction can improve the quality of life and curative effect by improving the electromyogram of upper limb flexion and elbow spasm and promoting blood circulation.
