Effects of Combined Tongue Three-Needle Acupuncture and Acupoint Application on Lianquan (CV 23) on Swallowing Function and Surface Electromyography Signals in Patients with Dysphagia after Ischemic Stroke
To observe the clinical effectiveness and potential mechanism of combined tongue three-needle acupuncture and acupoint application on Lianquan (CV 23) for patients with dysphagia after ischemic stroke.
Methods
2
A prospective study was conducted on 160 patients with post-stroke dysphagia, who were randomly divided into a treatment group and a control group, with 80 cases in each group. The control group received conventional rehabilitation training, while the treatment group received tongue three-needle acupuncture combined with acupoint application on Lianquan (CV 23) on the basis of conventional rehabilitation training, for 4 weeks in both groups. We compared the clinical effectivenss of both groups after treatment, and assessed the swallowing function including videofluoroscopic swallowing study (VFSS), standardized swallowing assessment (SSA) and functional oral intake scale (FIOS), swallowing contrast test including hyoid maximum displacement (HmaxD), pharyngeal transit time (PTT), and upper esophageal sphincter (UES) opening, surface electromyography (sEMG) test including maximum amplitude and swallowing duration as well as swallowing quality of life questionnaire (SWAL-QOL) score of the patients in both groups before treatment, after 2 weeks and 4 weeks of treatment, respectively.
Results
2
The total effective rate in treatment group was 82.50% (66/80), significantly higher than 66.25% (53/80) in control group (
P
<0.05). The VFSS, and FOIS scores, UES opening rate and HmaxD, sEMG maximal amplitude values, and SWAL-QOL scores were increased in both groups after 2 weeks and 4 weeks of treatment compared with the values before treatment (
P
<0.05), while SSA scores, PTT, and swallowing duration were decreased compared within group before treatment (
P
<0.05). VFSS and FOIS scores, UES opening rate and HmaxD, sEMG maximal amplitude values, and SWAL-QOL scores after 2 and 4 weeks of treatment in the treatment group were higher (
P
<0.05), while SSA scores, PTT, and swallowing duration were lower (
P
<0.05) than those in the control group at the same time.
Conclusion
2
Combined tongue three-needle acupuncture and acupoint application on Lianquan (CV 23) for patients with dysphagia after ischemic stroke can significantly improve swallowing activities, and its mechanism of action may be related to the improvement of the contraction ability and coordination of swallowing-related muscle groups.
