Objective

2

To observe the clinical effect of

reinforcing and reducing acupuncture method on post-stroke swallowing dysfunction (PSD) in the pharyngeal phase

and explore its biomechanical mechanism.

Methods

2

A total of 72 patients with PSD in the pharyngeal phase were randomly divided into a ziwureinforcing and reducing acupuncture group (36 cases

2 cases dropped out and 1 case was eliminated) and a conventional acupuncture group (36 cases

1 case dropped out and 1 case was eliminated). The patients in the conventional acupuncture group were treated with conventional acupuncture at Lianquan (CV 23) and bilateral Fengchi (GB 20)

Wangu (GB 12)

Tongli (HT 5)

Zhaohai (KI 6)

Hegu (LI 4)

Taichong (LR 3). The patients in the ziwu reinforcing and reducing acupuncture group were treated with

reinforcing and reducing acupuncture method on the basis of the conventional acupuncture group's acupoints. Both groups were treated with acupuncture for 30 min each time

once a day

and rested for 1 day after 6 days of treatment

and the treatment lasted 4 weeks. Before and after treatment

the standardized swallowing assessment (SSA) score

Rosenbek penetration aspiration scale (PAS) grade

the shortening rate of mandibular-hyoid distance

swallowing quality of life (SWAL-QOL) score were evaluated in the two groups. The removal rate of nasogastric feeding tube was compared in the two groups

and the clinical efficacy and safety of the two groups were compared.

Results

2

After treatment

the SSA scores and PAS grade of the two groups were lower than those before treatment (

P

<

0.001)

and above indexes in the ziwureinforcing and reducing acupuncture group were lower than

those in the conventional acupuncture group (

P

<

0.01

P

<

0.05). After treatment

the shortening rates of mandibular-hyoid distance and SWAL-QOL scores in the two groups were higher than those before treatment (

P

<

0.001)

and the shortening rate of mandibular-hyoid distance in the ziwureinforcing and reducing acupuncture group was higher than that in the conventional acupuncture group (

P

<

0.001). The removal rate of nasogastric feeding tube in the ziwureinforcing and reducing acupuncture group was 87.9% (29/33)

which was higher than 61.8% (21/34) in the conventional acupuncture group (

P

<

0.05). The total effective rate of the ziwureinforcing and reducing acupuncture group was 84.8% (28/33)

which was higher than 61.8% (21/34) of the conventional acupuncture group (

P

<

0.05). Neither group experienced serious adverse reactions.

Conclusion

2

CHEN Yinglong

ziwu

reinforcing and reducing acupuncture method can effectively improve swallowing dysfunction in the pharyngeal phase after stroke

reduce the risk of aspiration

and improve quality of life. Its therapeutic effect may be related to increasing the displacement amplitude of the hyoid bone.
