Objective : This study is purposed to investigate the effect of swallowing rehabilitation which is neuromuscular electrical stimulation therapy during meal training for improvement of the stroke patient`s swallowing function.
Methods : The 14 dysphagia patients caused by stroke were surveyed. The intervention provided those patients with neuromuscular electrical stimulation therapy using VitalStim while they are taking puree diet. We conducted the therapy 10 times with the frequencies between 12∼15 mA, 30 minutes per each time. Functional Dysphagia Scale(FDS) through Videofluoroscopic Swallowing Study(VFSS) was used, and then pre-test and post-test data were collected. The analysis of results was carried out through descriptive statistics, paired sample t-test.
Results : The result of this study shows that swallowing function of the stroke patients with dysphagia has improved since neuromuscular electrical stimulation therapy during meal training. Oral phase function and pharyngeal phase function of ``delayed swallow reflex`` and ``laryngeal elevation & folding of epiglottis`` indicated improvements, but there wasn`t significant effect. Whereas, significant effects were found in most of the pharyngeal phase including nasal penetration, residue in vallecular, residue in pyriform sinus, coated pharyngeal wall, laryngeal transit time.
Conclusion : The neuromuscular electrical stimulation therapy during meal times in stroke patients with dysphagia can improve the swallowing function through the promotion of the pharyngeal phase. Therefore, this intervention will be able to be utilized as an appropriate swallowing rehabilitation technique.
