Can acupuncture improve dysphagia?

Maybe... A study has been done evaluating acupuncture for dysphagia due to a stroke. Conclusion of study:" findings suggest that acupuncture may be useful for the treatment of post-stroke swallowing disorders. The specificity of the results to swallowing implies that its success is not simply a generalized response to acupuncture. Further studies are warranted in this area.".
Research. I agree with dr. Niknia - agkassi. Please see this site for a small but encouraging study on dysphagia improvement in stroke patients who received acupuncture.
Maybe. It is more likely to work in cases of functional rather than structural abnormality.
