Purpose: Although dysphagia is an important heath problem and one of determinant of quality of life in patients with dementia, the neurophysiologic changes of dysphagia in dementia have not been fully uncovered, yet. we investigated the changes of strength of tongue lip and pharyngeal muscles in patients with dementia.
Materials and Methods: This study included 30 subjects with dementia. In all subjects, clinical assessments were consisted of the Iowa Oral Performance Instrument (IOPI) for tongue and lip, surface electromyography (sEMG) with Vital stim plus on suprahyoid muscles, the Mini-Mental State Examination (MMSE), and Clinical Dementia Rating (CDR) scales.
Results: There was no difference between IOPI and sEMG among three sub-groups of dementia. The values of tongue IOPI from all three dementia groups were significantly lower than values of control (Figure 1). The comparisons for values of tongue IOPI among three dementia group were not significantly different from each other. The values of lip IOPI and sEMG of suprahyoid muscles were not different between three dementia groups and control.
Conclusion: The tongue strength by assessing IPOI was decreased in patients with all stages of dementia than controls. These findings would be useful for making therapeutic strategies for dysphagia in dementia. |
