To investigate the patterns of dysarthria in Korean patients with idiopathic peripheral facial palsy.Seventy-eight patients diagnosed with idiopathic peripheral facial palsy within the onset of symptom to 7 day time frame were prospectively enrolled. The initial symptom of facial palsy was examined by the House-Brackmann scale. All patients were tested by Urimal-Test of Articulation and Phonology-2 (U-TAP-2), which is specialized for the evaluation of dysarthria in Korean language - Hangeul - when the patients first visited and were followed up at 4 weeks after the onset, respectively. The facial electromyography was performed after 7 days, since the presentation of the first symptom. Electric stimulation therapy and simple facial exercise education were performed in all patients as routine treatments for facial palsy with or without dysarthria. The patterns of dysarthria were analyzed by initial and follow-up U-TAP-2 results, respectively.Among 78 patients, 50 patients (64.1%) had dysarthria in the first assessment. The 6 consonants and 3 vowels were errored in U-TAP-2 test. The bilabial consonants "ㅃ"[p] or "ㅍ" [p] were substituted with labiodental consonant [f], and palate-alveolar consonants were replaced by alveolar consonants - "ㅊ"[t(Equation is included in full-text article.)] to "ㅌ"[t]. Bilabial consonant "ㅁ"[m] was replaced by velar nasal consonant "ㅇ"[ŋ]. Liquid consonant was altered to nasal sound. For example, "ㄹ"[r] is replace by "ㄴ"[n]. The velar consonant "ㄲ"[k] was pronounced as "ㅋ" [k]. The diphthong vowels "ㅟ"[[Latin Small Letter Turned H]i], "ㅚ"[ø], or "ㅘ"[wa] were pronounced as monothong "ㅣ" [i], "ㅐ"[ε], or "ㅏ"[a], and "못"[mot] is slowly pronounced. After 4 weeks, 14 patients still showed pronunciation errors in 5 consonants and 3 vowels. The most common error was substitution.Among 78 patients with idiopathic peripheral facial palsy, 50 patients had dysarthria and 14 out of 50 patients with dysarthria lasted more than 4 weeks. Five consonants ("ㅁ", "ㅊ", "ㅍ", "ㄹ", "ㄲ") and 3 vowels ("ㅘ", "ㅗ", "ㅟ or ㅚ") were still mispronounced after 4 weeks, and most common error was substitution. Therefore, speech evaluation and speech therapy specialized for errors in high frequency of consonants and vowels are needed in patients with idiopathic peripheral facial palsy, in Korea.

Ataxic dysarthria often refers to disturbance of coordinated articulatory movements in SCD subjects. In our recent study of acoustic analysis of selected speech samples obtained from normal and ataxic subjects, it was revealed that the ataxic speech diagnosed as having "scanning" was characterized by slower speaking rate, inconsistent segment duration of both vowels and consonants, and significant shortening of phonemically long Japanese vowels, as compared to the normal speech. The findings are apparently different from those reported in the study of ataxic speech characteristics of the subjects speaking Germanic languages. Thus, the impression of "scanning" in Japanese ataxic subjects derives mainly from the breakdown of isochrony in terms of difficulty in keeping the length of segments (morae) of Japanese invariable during speech production. The acoustic analysis of selected Japanese sentences is considered to be one of the appropriate methods for objective evaluation of ataxic symptoms.

BACKGROUND
Deep brain stimulation of the subthalamic nucleus is an effective treatment of Parkinson's disease, yet it is often associated with a general deterioration of speech intelligibility. Clustering the phenotypes of dysarthria has been proposed as a strategy to tackle these stimulation-induced speech problems.
METHODS
In this study, we examine a cohort of 24 patients to test the real-life application of the proposed clustering and attempt to attribute the clusters to specific brain networks with two different approaches of connectivity analysis.
RESULTS
Both our data-driven and hypothesis-driven approaches revealed strong connections of variants of stimulation-induced dysarthria to brain regions that are known actors of motor speech control. We showed a strong connection between the spastic dysarthria type and the precentral gyrus and supplementary motor area, prompting a possible disruption of corticobulbar fibers. The connection between the strained voice dysarthria and more frontal areas hints toward a deeper disruption of the motor programming of speech production.
CONCLUSIONS
These results provide insights into the mechanism of stimulation-induced dysarthria in deep brain stimulation of the subthalamic nucleus and may guide reprogramming attempts for individual Parkinson's patients based on pathophysiological understanding of the affected networks.

The dysarthrias form a group of diverse, chronic motor speech disorders. The disorders of Parkinson's disease, stroke, traumatic brain injury, amyotrophic lateral sclerosis, and cerebral palsy are reviewed because they represent important clinical diagnoses in which dysarthria is a frequent and debilitating symptom. The roles played by speech-language pathologists include participation in differential diagnosis, provision of speech treatment, staging of treatment, and timely education so that clients and families can make informed decisions about communication alternatives. Both scientific and clinical evidence is presented that suggests that individuals with dysarthria benefit from the services of speech-language pathologists. Group-treatment studies, single-subject studies, and case reports illustrate the effectiveness of various types of speech treatment. Research into the effectiveness of augmentative and alternative communication systems for individuals with cerebral palsy is also presented.

PURPOSE
Patients with a neuromuscular disease (NMD) can present with dysarthria and/or dysphagia. Literature regarding prevalence rates of dysarthria and dysphagia is scarce. The purpose of this study was to determine prevalence rates, severity and co-presence of dysarthria and dysphagia in adult patients with NMD.
METHOD
Two groups of adult patients with NMD were included: 102 consecutive outpatients (the "unselected cohort") and 118 consecutive patients who were referred for multidisciplinary assessment (the "selected cohort"). An experienced speech-language pathologist examined each patient in detail.
RESULTS
The pooled prevalence of dysarthria was 46% (95% CI: 36.5-55.9) and 62% (95% CI: 53.3-70.8) in the unselected and selected cohorts, respectively. The pooled prevalence of dysphagia was 36% (95% CI: 27.1-45.7) and 58% (95% CI: 49.4-67.2) in the unselected and selected cohorts, respectively. There was a modest but significant association between the presence of dysarthria and dysphagia (rs = 0.40; p < 0.01). Although the dysphagia was generally mild, dysarthria was moderate to severe in 15% of the dysarthric patients.
CONCLUSION
The prevalence rates of dysarthria and dysphagia among patients with various types of NMD are high. Physicians should therefore be aware of this prevalence and consider referring NMD patients to a speech-language pathologist. IMPLICATONS OF REHABILITATION: Both dysarthria and dysphagia are highly prevalent among patients with neuromuscular diseases; moreover, although often mild, these disorders can occur relatively early in the course of the disease. Clinicians should routinely check for signs and symptoms related to dysarthria and/or dysphagia in patients who present with a neuromuscular disease, preferably using standardised instruments.

Review
PURPOSE
Motor speech abnormalities are highly common and debilitating in individuals with idiopathic Parkinson's disease (IPD). These abnormalities, collectively termed hypokinetic dysarthria (HKD), have been traditionally attributed to hypokinesia and bradykinesia secondary to muscle rigidity and dopamine deficits. However, the role of rigidity and dopamine in the development of HKD is far from clear. The purpose of the present study was to offer an alternative view of the factors underlying HKD.
METHOD
The authors conducted an extensive, but not exhaustive, review of the literature to examine the evidence for the traditional view versus the alternative view.
RESULTS
The review suggests that HKD is a highly complex and variable phenomenon including multiple factors, such as scaling and maintaining movement amplitude and effort; preplanning and initiation of movements; internal cueing; sensory and temporal processing; automaticity; emotive vocalization; and attention to action (vocal vigilance). Although not part of the dysarthria, nonmotor factors, such as depression, aging, and cognitive-linguistic abnormalities, are likely to contribute to the overall speech symptomatology associated with IPD.
CONCLUSION
These findings have important implications for clinical practice and research.

Review
There have been few reports describing the lesion for cerebellar dysarthria. We compared MRI findings of 4 reported patients (including our previously reported patient) to that of our patient who showed ataxic speech and ataxic gait. The lesions of 4 patients involved lobulus quadrangularis and lobulus simplex, and the lesion of the present patient involved lobulus semilunaris superior and lobulus simplex. Since lobulus simplex and lobulus quadrangularis were involved in many patients, we speculated that the cerebellar dysarthria of the present patient was due to the damage of these areas in the upper cerebellum.
