Abstract:
Objective:To seek any correlation between cortical activity and the swallowing of dysphagia patients with infratentorial stroke, and to observe any effect of three-needle acupuncture of the tongue on such activity.Methods:Thirty infratentorial stroke survivors with dysphagia were randomly divided into a tongue three-needle group and a sham acupuncture group, each of 15. Functional near-infrared spectroscopy was used to monitor changes in the concentration of oxygenated hemoglobin (ΔHbO 2) at rest, during acupuncture (or sham acupuncture), during real or sham electro-acupuncture, and at rest after the acupuncture or sham acupuncture treatment. The Modified Rankin Scale, a Penetration-Aspiration Scale (PAS), and the Functional Oral Intake Scale were employed to assess overall functional disability and the swallowing of both groups. Results:At rest the average ΔHbO 2 concentrations recorded in the left primary motor cortex, the left dorsolateral prefrontal cortex and the left premotor cortex in both groups were positively correlated with the PAS scores. During the acupuncture ΔHbO 2 concentration in the right inferior frontal gyrus and the left middle temporal gyrus increased significantly in the tongue three-needle group. It decreased significantly in the left somatosensory cortex and the left primary motor cortex. Conclusion:Three-needle acupuncture of the tongue induces changes in cortical activity in infratentorial stroke survivors with dysphagia, suggesting a potential technique for improving disordered swallowing.
