Objective To observe the effect of deep acupuncture of Tiantu(CV22)

etc.in combination with rehabilitation training on swallowing function of patients with post-stroke dysphasia.Methods A total of 70 patients suffering from poststroke dysphagia were randomly divided into control group(conventional acupuncture+swallowing rehabilitation training)and treatment group(deep acupuncture of CV22+rehabilitation training

n=35 cases in each group).The swallowing rehabilitation procedure was conducted 30 min every time

twice daily

5 times a week for 3 weeks.In patients of the treatment group

after deep insertion(about 80 mm)along the posterior margin of the manubrium sterna

the filiform needle in CV22 was lifted and thrusted repeatedly 9 times till the patient experienced a feeling of foreign matter blocking

followed by retaining the needle for 30 min.For patients of the control group

Lianquan(CV23)was punctured with 3 acupuncture needles(one vertical needling and bilateral slope needling toward the tongue root)

and Fengfu(GV16)

bilateral Bailao(EX-NH23)

bilateral Renying(ST9)and bilateral Jialianquan(Extra)were punctured vertically with filiform needles.The treatment was conducted once daily

5 times a week for 3 weeks.The swallowing function was evaluated by using Kubota water swallowing test(KWST)scale(0-5 points)

Fujishima Ichiro rating scale(FIRS

0-10 points)

and video fluoroscopic swallowing study(VFSS

0-10 points)

separately.The therapeutic effect was also assessed according to the clinical scale scores and VFSS results.Results Following the treatment

of the two 35 cases in the control and treatment groups

4(11.43%)and 8(22.86%)experienced marked improvement in their symptoms

22(62.86%)and 23(65.71%)were effective

and 9(25.71%)and 4(11.43%)were failed

with the effective rates being 74.29%and 88.57%

respectively.After the treatment

the KWST score of the two groups were significantly decreased in comparison with their own pre-treatment(P<0.05)

while the FIRS and VFSS scores of the two groups were considerably increased in comparison with their own pre-treatment(P<0.05).The therapeutic effects of the treatment group were obviously superior to those of the control group in the effective rate

lowering KWST score and in raising FIRS and VFSS scores(P<0.05).Conclusion Acupuncture plus swallowing rehabilitation training is effective in improving the swallowing function of stroke patients with dysphagia

and the deep acupuncture stimulation of CV22 is apparently better than conventional acupuncture in the therapeutic effect.
