Purpose: The primary goal of this study was to discover whether the articulatory diadochokinesis (sequential motionrate, SMR) collected using the Motor Speech Disorder Assessment (MSDA) software module can diagnose dysarthria and determine its severity. Methods: Two subject groups, one with spastic dysarthria (n=26) and a control group of speakers (n=30) without neurological disease, were set up. From both groups, the SMR was collected by MSDA at a time, and then analyzed using descriptive statistics. Results: For the parameters of syllable rate, jitter, and the mean syllable length (MSL) at the front and back, the control group displayed better results than the dysarthria patients. Conclusions: At the level of articulatory diadochokinesis, the results showed that the use of MSDA software in clinical practice was generally suitable for quickly recording the parameters of syllable rate, jitter, and mean syllable length.

This study acoustically examines the quality of fricatives produced by ten dysarthric speakers with cerebral palsy. Previous similar studies tend to focus only on sibilants, but to obtain a better understanding of how dysarthria affects fricatives we selected a range of samples with different places of articulation and voicing. The Universal Access (UA) Speech database was used to select thirteen words beginning with one of the English fricatives (/f/, /v/, /s/, /z/, /ʃ/, /ð/). The following four measurements were taken for both dysarthric and healthy speakers: phoneme duration, mean spectral peak, variance and skewness. Results show that even speakers with mild dysarthria have significantly longer fricatives and a lower mean spectral peak than healthy speakers. Furthermore, mean spectral peak and variance showed significant group effects for both healthy and dysarthric speakers. Mean spectral peak and variance was also useful for discriminating several places of articulation for both groups. Lastly, spectral measurements displayed important group differences when taking severity into account. These findings show that in general there is a degradation in the production of fricatives for dysarthric speakers, but difference will depend on the severity of dysarthria along with the type of measurement taken.

1. Objective This case study reports a Taeeumin patient experiencing hand tremor, heat flash, and mild dysarthria who improved with Yeoldahansotang medication. 2. Method The patient's subjective and objective symptoms were observed daily, and the VAS scores for the main symptoms (hand tremor, heat flash, and mild dysarthria) were recorded daily throughout hospitalization period. 3. Result The patient's general conditions improved by the end of hospitalization, and VAS score dropped dramatically from VAS 10, VAS 10, VAS 10 to VAS 0, VAS 0.5, VAS 3 for hand tremor, heat flash, and mild dysarthria, respectively. 4. Conclusion The patient responded well to Yeoldahansotang, one of the main medicaments for the Joyeol (dry-heat) symptomatic pattern, which indicates that Yeoldahansotang can be used to treat the Joyeol symptomatic pattern even when the textbook indications are not evident as long as the Joyeol pathology is recognizable from other symptoms.

The aim of this study was to analyze consonant articulation errors produced by 90 speakers with cerebral palsy (CP). Phonetic transcriptions were made for 37 single-word utterances containing 70 phonemes: 48 initial consonants and 22 final consonants. Errors of substitution, omission, and distortion were analyzed using a confusion matrix paradigm showing the visualization of error patterns. Results showed that substitution errors in initial and final consonants were most frequent, followed by omission and distortion. Consonant omission occurred more frequently on final consonants. In both initial and final consonants, the within-place errors were more prominent than the within-manner errors. The current results suggest that consonant confusion matrices for dysarthric speech may provide useful information for evaluating speech intelligibility and developing automatic speech recognition system of adults with CP associated dysarthria.

Isolated hypoglossal nerve palsy is a rare clinical condition and it causes deviation of the tongue and dysarthria. A 50-year-old female presented with tongue deviation to the left and mild dysarthria. She had no remarkable past medical history except several recent upper respiratory infections. On examination, the other cranial nerves were intact and she had no focal neurological signs. The findings of MRI and MR angiography were normal. Cerebrospinal fluid analysis revealed only mild elevation of protein. We diagnosed her as suffering with idiopathic isolated hypoglossal nerver palsy and we administered steroid therapy. The dysarthria was improved, but the tongue deviation still remained at 50 days after onset. We report here on a rare case of idiopathic isolated hypoglossal nerve palsy.

In the previous studies, some characteristics of flaccid dysarthria patients have been studied mainly in two aspects: their difficulties in articulation and their metrical dysfunction. Therapeutic research on the articulation impediment of the patients have been carried out extensively (Yorkston, 1981). However, their phonetic characteristics have been less well-studied. The aim of this paper is to measure and describe some phonetic differences between the normal speaker group (six speakers) and the flaccid dysarthria patient group (six speakers in three different degreed of severity). Two types of short sentences comprising of subject-object-verb, i.e. declarative and yes-no question sentences, were recorded to investigate some phonetic characteristics of these two groups of speakers. The two groups (normal group vs. patient group) show differences in yes-no question boundary tone (H% vs. HL%), pitch range (wide vs. narrow), duration (short vs. long) and intensity (strong vs. weak) of sentence final verb endings in Korean.

Objectives: This study investigated the treatment response to Korean medicine of a paraneoplastic cerebellar degeneration (PCD) patient with dysarthria and weakness of distal extremity. Case presentation: A 53-year-old female diagnosed with PCD complained of dysarthria and weakness of distal extremity. During 32-day hospitalization, she was treated with Korean medicine, namely, herbal medicine (modified Gamiguibi-tang), acupuncture (15 minutes twice a day at CV23, HT7, LI4, LR3, ST36, SP6, GB20, TE17, PC6, GV20, Ex-HN1, GV24 etc.), moxibustion, and cupping, combined with Western medicine (prednisolone, azathioprine) and physical therapy. Post-treatment, the patient global assessment (PGA) score of dysarthria fell from 100 to 60; grasp power rose from 15 kg to 19 kg and 13 kg to 17 kg in the right and left hands, respectively; and the 5-level EQ-5D version (EQ-5D-5L), EQ visual analogue scale (EQ-VAS), and Beck depression inventory (BDI-II) scores changed from 10 to 8, 0 to 80, and 34 to 7 respectively. Follow-up visits continued for about a month after discharge, improvement in symptoms maintained, and there were no significant side effects. Conclusions: Given the lack of standard treatment for PCD, Korean medicine can be tried clinically for the treatment of PCD patients with dysarthria and weakness of distal extremity. However, further studies with control groups are needed.

Objective: The purpose of this clinical study is to report the effect of Banhahoobak-tang in the case of a 57-year-old woman with multiple cerebral infarction causing dysphagia and dysarthria diagnosed as pseudobulbar palsy. Methods: A patient was treated with Korean medicine, including herbal medication, acupuncture, and language therapy. We focused on the effect of Banhahoobak-tang by evaluating improvements in symptoms by examining times of aspiration and changes in Speech Mechanism Screening Test scores. Results: After three months of Korean medicine treatment and language therapy, there was improvement in the patient's symptoms, including dysphagia and dysarthria. Conclusions: This study suggests that Korean medicine treatment could be effective for improving the symptoms of pseudobulbar palsy in patients. Specifically, herbal medicine (Banhahoobak-tang) could be an effective choice for treating dysphagia.
