Dysphagia affects a significant number of patients with Alzheimer's dementia. Neuromuscular electrical stimulation may be a promising resource for dysphagia rehabilitation in this population.
To investigate the immediate effects of neuromuscular electrical stimulation on hyoid bone displacement, pharyngeal transit time, and swallowing safety in elderly people with Alzheimer's dementia.
We evaluated 30 elderly individuals with an average age of 82.79 years, regardless of the stage of dementia and with reduced hyolaryngeal elevation, using the Northwestern Dysphagia Patient Check Sheet. Neuromuscular electrical stimulation was performed at the sensory and motor levels in the submental region during videofluoroscopy, with food being offered in solid, pudding, and liquid consistencies, and in portions of 5 mL and 10 mL. We applied Analysis of variance and the Friedman test, adopting a significance level of < 5%.
The comparison between the sensory and motor levels of stimulation showed that there was a significant difference in hyoid bone displacement for the mushy consistency, with neuromuscular stimulation at the motor level. There was no difference in the application of stimuli for the other consistencies regarding hyoid bone displacement, pharyngeal transit time, and the penetration and aspiration scale.
In elderly people with Alzheimer's dementia, neuromuscular electrical stimulation at the motor level generated a reduction in hyoid bone displacement during swallowing of food with pudding consistency, with no effects on pharyngeal transit time or swallowing safety.
吞咽困难影响着大量阿尔茨海默病痴呆患者。神经肌肉电刺激可能是这类人群吞咽困难康复的一种有前景的方法。
研究神经肌肉电刺激对患有阿尔茨海默病痴呆的老年人舌骨位移、咽部通过时间和吞咽安全性的即时影响。
我们使用西北吞咽困难患者检查表评估了30名平均年龄为82.79岁的老年人，这些患者不论痴呆阶段且喉舌抬高降低。在透视吞咽造影检查期间，于颏下区域的感觉和运动水平进行神经肌肉电刺激，提供固体、布丁和液体三种稠度的食物，量分别为5毫升和10毫升。我们采用方差分析和弗里德曼检验，显著性水平设定为<5%。
刺激的感觉和运动水平之间的比较显示，对于糊状稠度的食物，运动水平的神经肌肉刺激在舌骨位移方面存在显著差异。在舌骨位移、咽部通过时间以及渗透和误吸量表方面，其他稠度食物的刺激应用没有差异。
对于患有阿尔茨海默病痴呆的老年人，运动水平的神经肌肉电刺激在吞咽布丁状食物时会使舌骨位移减少，对咽部通过时间或吞咽安全性无影响。
