Clinical trials of Xingnao Kaiqiao needling combined with respiratory training for post-stroke dysphagia

Abstract

To observe the clinical effect of Xingnao Kaiqiao needling combined with respiratory training on swallowing function, quality of life and throat surface muscle function in patients with post-stroke dysphagia. A total of 124 patients with post-stroke dysphagia were randomized into an observation group and a control group, 62 cases in each group. On the basis of conventional western medication treatment, respiratory training was applied in the control group, once daily, 5 times a week for 4 weeks. On the base of the treatment as the control group, Xingnao Kaiqiao needling was applied at Neiguan (PC6), Sanyinjiao (SP6), Fengchi (GB20), Wangu (GB12), Yifeng (SJ17), posterior pharyngeal wall, Shuigou (GV26) and Lianquan (CV23) in the observation group, once daily, 6 times a week for 4 weeks. Before and after treatment, the Kubota water swallowing test (KWST) scale, swallowing function, swallowing-quality of life (SWAL-QOL) scale, maximum amplitude of pharyngeal surface electromyography (sEMG), and complications of dysphagia were observed and recorded. After the treatment, self-comparison showed that the KWST and swallowing function scores were significantly decreased (P<0.05), the SWAL-QOL score and sEMG were notably increased in both groups (P<0.05) in comparison with their own pre-treatment. The KWST and swallowing function scores were obviously lower in the observation group than in the control group (P<0.05), whereas the SWAL-QOL score and sEMG were evidently higher in the observation group than in the control group (P<0.05). The total effective rate of the observation group was 95.16% (59/62), which was higher than 80.65% (50/62) of the control group (P<0.05). The incidence of dysphagia complications in the observation group was 24.19% (15/62), which was lower than 50.00% (31/62) of the control group (P<0.01). Xingnao Kaiqiao needling combined with respiratory training in the treatment of post-stroke dysphagia can increase the activity of throat muscles, promote the swallowing function, improve the quality of life, and reduce the incidence of dysphagia related complications.
