[Effects of GAO's neck acupuncture on swallowing function and quality of life in patients with post-stroke pseudobulbar palsy:a randomized controlled trial]

Abstract

Objective: To observe the effects of GAO's neck acupuncture combined with swallowing rehabilitation on swallowing function and quality of life in patients with post-stroke pseudobulbar palsy.

Methods: One hundred patients were randomly assigned in to an observation group and a control group, 50 cases in each one. The patients in the control group were treated with basic pharmaceutical treatment, including neurotrophy medication and free radical scavenging medication as well as swallowing rehabilitation; the patients in the observation group, on the basis of those in the control group, were treated with GAO's neck acupuncture at Fengchi (GB 20), Yiming (EX-HN 14), Gongxue (Extra), Lianquan (CV 23), Wai Jinjin Yuye (Extra), Tunyan (Extra), Zhiqiang (Extra), Fayin (Extra), once a day, five times a week for continuous eight weeks. The Repetitive saliva-swallowing test (RSST), standardized swallowing assessment (SSA) and swallow quality-of-life questionnaire (SWAL-QOL) before and after treatment in the two groups were observed; the relationship between disease location and frequency and efficacy of GAO's neck acupuncture was explored in the observation group.

Results: After treatment, the RSST, SSA and SWAL-QOL were superior to those before treatment (all P<0.01), with more significant results in the observation group (all P<0.01). The total effective rate was 91.7% (44/48) in the observation group, which was superior to 75.5% (37/49) in the control group (P<0.01). The frequency of disease onset was one in 11 patients and 2 and above in 37 patients in the observation group, and the efficacy of one onset of disease was 100.0% (11/11), which was superior to two and above of onset 89.2% (33/37, P<0.01). The number of patients with disease location at cortex and subcortex was 21, while that at capsula interna and basal ganglia was 27 in the observation group, the efficacy of two was similar (P>0.05).

Conclusions: GAO's neck acupuncture combined with swallowing rehabilitation could effectively improve dysphagia and quality of life in patients with post-stroke pseudobulbar palsy. No correlation of lesion locations on acupuncture efficacy is observed, while onset frequency is inversely proportional to efficacy.
