To evaluate the effects of tension balance needling on limb motor function and surface electromyography in patients with spastic state of stroke. Methods:A total of 60 patients with spastic state of stroke were included from the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine from January 2016 to December 2018，and randomly divided into observation group(30 cases)and control group(30 cases). In the 2 groups，a course of treatment consisted of 10 times of acupuncture treatment，and 2 courses of treatment were observed. Before and after treatment，the Modified Ashworth Spasm Scale(MAS)，Fugl-Meyer Motor Function(F-M)score，NDS overall score，overall clinical efficacy and RMS value of surface electromyography were compared between the 2 groups. Results:1)The total effective rate of the observation group was 86.67%，and that of the control group was 73.33%. The curative effects of the 2 groups were compared(P>0.05). 2)After treatment，the scores of MAS in both groups were significantly decreased(P<0.05); after treatment，the score of MAS in the observation group was significantly lower than that in the control group(P<0.05). 3)The simplified F-M score of patients with spastic state of stroke in both groups can be effectively improved. Compared with the simplified F-M score before treatment，the score of the 2 groups increased in different degrees after treatment(P<0.01). The improved F-M score of the observation group was better than that of the control group after treatment，and the simplified F-M score of the observation group was higher than that of the control group after treatment(P<0.05). 4)After treatment，the overall score of NDS in the observation group was lower than that in the contrl group(P<0.05); compared with before treatment，the overall score of NDS in the 2 groups decreased in varying degrees after treatment(P<0.05). Both treatments could improve the overall score of NDS，and the observation was superior to the control group in terms of the degree of overall clinical neurological deficits. 5)Compared with before treatment，the RMS values of biceps brachii and quadriceps femoris in the 2 groups decreased in different degrees after treatment(P<0.05)，and the RMS values of biceps brachii and quadriceps femoris in the observation were lower than those in the control group(P<0.05). Both treatments could improve the RMS values of biceps brachii and quadriceps femoris，and the observation group was better than the control group. Conclusion:1)Tension balance needling and routine needling are effective in treating spastic state of stroke. 2)Both tension balance needling and routine needling can reduce the influence of neurological deficit and improve limb motor function in patients with spastic stroke，and the long-term effect of the observation group is better than that of control group.
