Abstract
ObjectiveThe objective of this study was to utilize ultrasonography to measure the movement-related characteristics of the hyoid bone-mandible in patients with dysphagia in order to quantitatively evaluate the clinical efficacy of acupuncture as a treatment for dysphagia following brain infarction. MethodsA total of 63 patients with dysphagia following a brain infarction were randomly assigned into two groups: one receiving meridian point treatments and the other receiving non-meridian and non-point treatments. The meridian point group received routine treatment using the meridian point acupuncture method, and the true acupuncture intervention mode of qi arrival plus swift pricking blood therapy was utilized. The non-meridian and non-acupoint group received conventional treatment using the pseudo-acupuncture mode of non-acupoint without qi arrival. Both groups received treatment once daily, five times per week, for a duration of four weeks. Video fluoroscopic swallowing study (VFSS) was used to diagnose dysphagia in all patients, and FOIS and PAS were also used for clinical assessment. Results(i) Clinical efficacy comparison: After 4 weeks of treatment, the meridian group showed superior efficacy compared to the non-meridian and non-acupuncture group (P < 0.05). The FOIS score of the meridian acupoint group was also higher than that of the non-meridian and non-acupoint group (P < 0.05). In addition, the dilute fluid food PAS score in the meridian acupoint group was lower than that in the non-meridian and non-acupoint group (P < 0.05). (ii) Comparison of ultrasonography: The hyoid-mandibular comparison of the shortening distance, shortening rate, and movement speed of the bone movement were measured in both groups after 2 weeks and 4 weeks of treatment. The results indicated that the improvement in the meridian group was better than that in the non-meridian and non-acupoint group in all measurements (P < 0.05). ConclusionPatients with swallowing disorders exhibit impaired hyoid-mandibular movement. However, the implementation of true acupuncture intervention can enhance hyoid-mandibular movement function, ultimately leading to an improvement in swallowing function.
