This pilot study suggests acupuncture may effectively improve swallowing in stroke patients with dysphagia. Further large-scale trials are recommended to confirm these promising findings for post-stroke dysphagia management.

Area of Science:

Neurology
Integrative Medicine
Rehabilitation

Background:

Post-stroke dysphagia is a common complication impacting patient recovery and quality of life.
Current treatments for post-stroke dysphagia have limitations, necessitating exploration of alternative therapies.

Purpose of the Study:

To evaluate the effectiveness and safety of acupuncture for treating dysphagia in stroke survivors.
To provide preliminary data for future large-scale randomized controlled trials.

Main Methods:

A multicenter, pragmatic, nonrandomized, self-controlled clinical trial involving 39 participants.
Acupuncture treatment administered over two months, with swallowing function assessed using the Royal Brisbane Hospital Outcome Measure for Swallowing (RBHOMS) and Swallow Quality-of-Life Questionnaire.

Published on: March 1, 2015

Main Results:

Acupuncture treatment led to statistically significant improvements in RBHOMS scores compared to baseline and retrospective data (p=0.006 and p=0.042, respectively).
Significant improvements were also observed in swallow quality-of-life scores post-acupuncture (p < 0.01).

Conclusions:

Acupuncture shows preliminary effectiveness in improving swallowing function and quality of life for patients with post-stroke dysphagia.
This study supports acupuncture as a potential therapeutic option and provides a basis for future rigorous clinical trials.
