TL;DR: 両面から, dysarthriaの音響的特徴および分節的样調することで構音も改善されている可能性を示唆していた.
Abstract: 韻律的特徴および分節的特徴の両面から, dysarthriaの音響的特徴の評価を行った.共通の結果としては, 基本周波数 (F0) レンジの縮小が今回評価したすべてのdysarthriaに対して観察された.さらに, 原因疾患の違いがF0の分布の違いに反映されていた.また, 子音/母音のパワーおよび5母音のフォルマント周波数の対比はdysarthriaでは弱められていた.上記分析結果はまた, F0レンジと母音のフォルマント周波数の問に関連があり, 音声訓練によって韻律を強調することで構音も改善されている可能性を示唆していた.

TL;DR: This is the first report on the MRI findings of the patient who showed pure dysarthria, which responsible lesion is in the pontine base, which may be useful for the somatotopy of corticopontine and corticobulbar tracts with articulation in the Pontine base.
Abstract: A 60-year-old man developed dysarthria in the morning. Neurological examination revealed no abnormality except for dysarthria. We diagnosed the patient as having a lacunar infarction. T2-weighted brain MRI revealed hyperintense lesion in the ventrolateral portion of the left upper pontine base. The clinical symptom completely disappeared on day 20. This is the first report on the MRI findings of the patient who showed pure dysarthria, which responsible lesion is in the pontine base. Involvement of corticopontine and corticobulbar tracts were considered to be responsible for the dysarthria in this case. This case may be useful for the somatotopy of corticopontine and corticobulbar tracts with articulation in the pontine base.

TL;DR: From the results of this study, it was suggested that NSV would be effective in cerebrovascular disease and neurodegenerative disease, as well as in subjects whose speech intelligibility was improved by closing nostrils.
Abstract: Summary Velopharyngeal incompetence is known as a contributing factor to speech disorders. Suwaki et al. reported that nasal speaking valve (NSV) could improve dysarthria by regulating nasal emission utilising one-way valve. However, disease or condition which would be susceptible to treatment by NSV has not been clarified yet. This study aimed to evaluate the effect of NSV by questionnaire survey using ready-made NSV. Subjects were recruited through the internet bulletin, and NSV survey set was sent to the applicant. Sixty-six participants, who agreed to participate in this study, used NSV and mailed back the questionnaire which included self-evaluation and third-party evaluation of speech intelligibility. Statistical analysis revealed that the use of NSV resulted in significant speech intelligibility improvement in both self-evaluation and third-party evaluation (P < 0·01). Regarding the type of underlying disease of dysarthria, significant effect of NSV on self-evaluation of speech intelligibility could be observed in cerebrovascular disease and neurodegenerative disease (P < 0·01) and that on third-party evaluation in neurodegenerative disease (P < 0·01). Eighty-six percent of subjects showed improvement of speech intelligibility by shutting up nostrils by fingers, and the significant effect of NSV on both self-evaluation and third-party evaluation of speech intelligibility was observed (P < 0·001). From the results of this study, it was suggested that NSV would be effective in cerebrovascular disease and neurodegenerative disease, as well as in subjects whose speech intelligibility was improved by closing nostrils.

TL;DR: Although the patient had the symptoms of bilateral ptosis and diplopia, dysarthria, dysphagia, and respiratory muscle weakness, she did not show any symptoms of injury of the pyramidal tracts, which were most common when bilateral brain stem lesions were involved.
Abstract: lesions in the brain stem. Although the patient had the symptoms of bilateral ptosis and diplopia, dysarthria, dysphagia, and respiratory muscle weakness, she did not show any symptoms of injury of the pyramidal tracts, which were most common when bilateral brain stem lesions were involved. Her motor system symptoms were the injuries of lower motor neuron or peripheral nerve symptoms. Hence, brain stem lesions were not considered. In addition, this patient was ventilated 3 days after admission, and brain magnetic resonance imaging could not be performed.
