不同波形参数电针治疗中风后吞咽困难的疗效分析OA

Objective:To explore the clinical efficacy differences of electroacupuncture with different waveform parameters in treating post-stroke dysphagia.Methods:Sixty patients with post-stroke dysphagia meeting the inclusion criteria were randomly divided into two groups using a random number table:the sparse-dense wave group(2/100 Hz)and the sparse wave group(2 Hz),with 30 patients in each group.Based on the"Evidence-Based Acupuncture Clinical Practice Guidelines"published by the Chinese Acupuncture Society,acupuncture points including Lianquan(LI4),Jialianquan(LI11),Fengchi(GB20),Gongxue(ST36),Yifeng(TE5),Lieque(LU7),Zhaohai(KD6),Tongli(PC8),and Neiguan(PC6)were selected.Different waveform parameters were applied in electroacupuncture treatment,administered once daily,6 days a week,for 4 weeks.The changes in swallowing function were assessed using the Water Swallowing Test and the Standard Swallowing Assessment(SSA)scale before treatment,after 2 weeks,and after 4 weeks.Clinical efficacy was compared between the two groups.Results:The total clinical effective rate was 93.33%(28/30)in the sparse-dense wave group and 76.67%(23/30)in the sparse wave group,with a statistically significant difference(P<0.05).Compared to before treatment,the Water Swallowing Test scores and SSA scores decreased in both groups after 2 and 4 weeks of treatment(P>0.05).The sparse-dense wave group showed a more significant reduction in Water Swallowing Test scores and SSA scores after 4 weeks compared to the sparse wave group(P<0.05).Conclusion:Both the 2/100 Hz sparse-dense wave and 2 Hz sparse wave treatment protocols can improve swallowing function in patients,but the sparse-dense wave shows superior long-term efficacy compared to the sparse wave.
