[Therapeutic effect of nape cluster acupuncture combined with swallowing function training on post-stroke dysphagia]
1School of Acupuncture-Moxibustion and Tuina, Liaoning University of TCM, Shenyang 110032, China.
Objective:
To observe the effect on swallowing function in patients with post-stroke dysphagia treated with nape cluster acupuncture and the immediate effect of acupuncture at Fengchi (GB 20).
Methods:
A total of 60 patients with post-stroke dysphagia were randomized into an observation group and a control group, 30 cases in each one.On the basis of conventional western medication treatment, swallowing function training was applied in the control group, once a day.On the base of the treatment as the control group, nape cluster acupuncture was applied at Fengchi (GB 20), Tianzhu (BL 10), Wangu (GB 12), Lianquan (CV 23), Panglianquan (Extra), Jinjin (EX-HN 12) and Yuye (EX-HN 13) in the observation group, once a day. Additionally, pricking blood was applied at Jinjin (EX-HN 12) and Yuye (EX-HN 13), 2 times a week. The treatment was given 30 min each time, a week as one course and 4 courses were required. Before and after treatment, the standardized swallowing assessment (SSA) score and video fluoroscopic swallowing study (VFSS) score were compared in the two groups. The ultrasonic diagnostic device of swallowing and surface electromyography were used to observe the immediate effect on swallowing related muscles of acupuncture at Fengchi (GB 20).
Results:
Compared before treatment, the SSA scores were reduced after treatment in the two groups (P<0.05), and the change of the observation group was larger than the control group (P<0.05). Compared before treatment, the VFSS scores were increased after treatment in the two groups (P<0.05), and the change of the observation group was larger than the control group (P<0.05). Acupuncture at Fengchi (GB 20) immediately increased the amplitude of submental muscles and infrahyoid muscles in the observation group (P<0.05), the geniohyoid muscle movement time was reduced and geniohyoid muscle displacement was increased (P<0.05).
Conclusion:
On the base of the routine treatment, nape cluster acupuncture could improve swallowing function in patients with post-stroke dysphagia. Acupuncture at Fengchi (GB 20) could immediately affect swallowing related muscles, improve muscle amplitude and reduce swallowing time.
