This study investigated the practice patterns used by Malaysian speech-language pathologists (SLPs) with patients with dysarthria, identified challenges perceived by SLPs and explored strategies to address perceived barriers for improving dysarthria management. Two studies were conducted. Study 1 disseminated a 30-item survey questionnaire electronically via google link to SLPs in the Malaysian Speech-Language-Hearing Association through e-mail lists. Responses were analysed using descriptive statistics. In Study 2, semi-structured interviews of twelve SLPs who managed patients with dysarthria were conducted. Data were transcribed verbatim and analysed using the thematic analysis method. Three major themes and ten sub-themes emerged from the interviews, including "assessment and treatment practices", "challenges", and "overcoming challenges". SLPs' practice of assessment and treatment of dysarthria were predominantly impairment-based. Respondents (64%) who never used standardised assessment tools valued textbooks more as sources of evidence and had a lower level of confidence in their knowledge about dysarthria compared to those who used standardised tools. Focus now needs to be on the education needs of our SLPs, on both the university training and continuing education levels, for direction of the development of professional training courses. Ongoing research and public awareness are required to guide clinical management decisions.

PURPOSE
This study aimed to improve understanding of speech characteristics associated with dysarthria in children with cerebral palsy by analyzing segmental and global formant measures in single-word and sentence contexts.
METHOD
Ten 5-year-old children with cerebral palsy and dysarthria and 10 age-matched, typically developing children participated in this study. Vowel space area and second formant interquartile range were measured from children's elicited productions of single words and sentences.
RESULTS
Results showed that the children with dysarthria had significantly smaller vowel space areas than typically developing children in both word and sentence contexts; however, overall ranges of second formant movement did not differ between groups in word or sentence contexts. Additional analysis of single words revealed that, compared to typical children, children with dysarthria had smaller second formant interquartile ranges in single words with phonetic contexts requiring large changes in vocal tract configuration, but not in single words with monophthongs.
CONCLUSIONS
Results of this study suggest that children with dysarthria may not have globally reduced ranges of articulatory movement compared to typically developing peers; however, they do exhibit reduced precision in producing phonetic targets.

Review
INTRODUCTION
Hyperkinetic dysarthria is characterized by atypical involuntary movements within the speech mechanism that may affect the respiratory, laryngeal, pharyngeal-oral, or velopharyngeal-nasal subsystems and may alter speech production. Although articulatory impairments are commonly considered in hyperkinetic dysarthria, speakers with hyperkinetic dysarthria may also present with changes in voice quality, pitch, and loudness. In approximately 70% of speakers with hyperkinetic dysarthria, these voice alterations are associated with tremor or dystonia. The purpose of this systematic review was to investigate the association between behavioral therapy for tremor or dystonia affecting voice in speakers with hyperkinetic dysarthria and improvement in the functional, perceptual, acoustical, aerodynamic, or endoscopic characteristics of voice.
METHOD
MEDLINE (PubMed), Embase, PsycINFO, and ClinicalTrials.gov online databases were searched in August 2017, December 2018, and April 2020 for relevant studies. The searches provided 4,921 unique records, and six additional unique records were added from other sources. Twelve studies met the criteria for inclusion in the systematic review. Participants who received concurrent medical treatment were included in this review to ensure that the search was inclusive of all relevant studies and informative for typical clinical scenarios.
RESULTS
The most commonly administered treatment ingredient was relaxation training, which was investigated in three of the four studies on tremor and three of the eight studies on dystonia. Of these six studies, only one used an experimental design and administered relaxation training as the only behavioral approach. This single-case experiment reported a significant reduction in participant ratings of tremor severity and interference with activities of daily living, although the speaking subscale reportedly did not improve and oral medications were administered concurrently. In two group studies that tested potential behavioral therapy targets, production of a low pitch improved acoustical measures for participants with essential tremor and improved auditory-perceptual judgments for participants with laryngeal dystonia. Behavioral therapy improved functional, acoustical, and aerodynamic outcomes in participants with laryngeal dystonia who were also receiving botulinum toxin injections in a randomized cross-over study and a non-randomized controlled study. Because one study employed easy onset and breathing exercises, while the other employed loud voice exercises, the mechanism of action for improvement in voice associated with behavioral therapy requires further investigation.
CONCLUSION
This systematic review describes the current evidence for treatment of tremor and dystonia affecting voice in speakers with hyperkinetic dysarthria and highlights the need for future research on behavioral therapy for these disorders.

BACKGROUND
A comprehensive evaluation of dysarthria is required to make an accurate differential diagnosis with other communication disorders and plan effective rehabilitation programs. The Frenchay Dysarthria Assessment-2 (FDA-2) is a valid, reliable and widely used protocol for the assessment of dysarthria. An Italian version of the FDA-2 is currently lacking.
AIM
To perform a cross-cultural adaptation of the FDA-2 in Italian and to validate the Italian version of the FDA-2.
DESIGN
Validation study.
SETTING
Inpatient rehabilitation center.
POPULATION
69 patients with dysarthria and 112 healthy controls.
METHODS
The FDA-2 was translated and cross-culturally adapted to Italian. The validation study was carried out in 4 steps: (1) 42 audio-recorded samples of FDA-2 items from 11 patients with dysarthria were independently assessed by 7 speech and language pathologists for interrater reliability and re-assessed after 6 weeks for intrarater reliability; (2) 11 patients were simultaneously assessed by 3 speech and language therapists for interrater reliability of the whole Italian version of the FDA-2 and re-assessed within 24 hours for test-retest reliability; (3) the Italian version of the FDA-2 was administered to 112 healthy volunteers to gain normative data; (4) 49 patients with different types of dysarthria were assessed using the Italian version of the FDA-2, the Therapy Outcome Measure impairment scale and the Robertson Profile for the validity analysis.
RESULTS
Interrater and intrarater reliability ranged from good to excellent (ICC >0.75) except for 3 audio-recorded items. The overall protocol demonstrated excellent (ICC >0.9) inter-rater and test-retest reliability for all the sections and the total score. Normative data were gained for 6 age groups. For the validity analysis, a statistically significant difference was found between dysarthric patients and healthy subjects for all sections and the total score. The FDA-2 significantly correlated to the therapy outcome measure (r=0.75) and the Robertson Profile (r=0.81).
CONCLUSIONS
The Italian version of the FDA-2 yield satisfactory reliability and validity, comparable to the psychometric properties of the original version.
CLINICAL REHABILITATION IMPACT
Speech and language pathologists can rely on a valid and reliable tool in Italian for the assessment of dysarthria in both clinical and research practice.

Purpose This preliminary study examined whether speech profiles exist for adults with hereditary ataxia based on 2 competing frameworks: a pattern of instability/inflexibility or a pattern of differential subsystem involvement. Method Four dysarthria experts rated the speech samples of 8 adults with dysarthria from hereditary ataxia using visual analog scales and presence/severity rating scales of speech characteristics. Speaking tasks included diadochokinetics, sustained phonation, and a monologue. Results Speech profiles aligned with the instability/inflexibility framework, with the pattern of instability being the most common. Speech profiles did not emerge for the majority of speakers using the differential subsystem framework. Conclusions The findings extend previous research on pure ataxic dysarthria and suggest a possible framework for understanding the speech heterogeneity associated with the ataxias. The predominance of the instability profile is consistent with the notion of impaired feedforward control in speakers with cerebellar disruption.

Although tongue twisters have been widely use to study speech production in healthy speakers, few studies have employed this methodology for individuals with speech impairment. The present study compared tongue twister errors produced by adults with dysarthria and age-matched healthy controls. Eight speakers (four female, four male; mean age = 54.5 years) with spastic (mixed-spastic) dysarthria of varying aetiology (cerebral palsy, multiple sclerosis, multiple system atrophy) and eight controls (four female, four male; mean age = 56.9 years) were audio-recorded producing tongue twisters. One word in each tongue twister was marked for prominence. Speakers with dysarthria produced significantly more errors and spoke slower than healthy controls. The effect of prominence was significant for both groups-words spoken with prosodic prominence were significantly less error prone compared with words without prominence. While both groups produced most errors on words in the third position (of four-word utterances), speakers with dysarthria also produced high rates of errors on the first and fourth words. This preliminary investigation demonstrated the promise of applying the tongue twister paradigm to speakers with dysarthria and contributes to the evidence base for the implementation of prosodic strategies in speech intervention.

Parkinson's disease (PD) is a progressive neurological disorder characterized by several motor and non-motor manifestations. PD frequently leads to hypokinetic dysarthria, which affects speech production and often has a detrimental impact on everyday communication. Among the typical manifestations of hypokinetic dysarthria, speech and language therapists (SLTs) identify prosody as the most affected cluster of speech characteristics. However, less is known about how untrained listeners perceive PD speech and how affected prosody influences their assessments of speech. This study explores the perception of sentence type intonation and healthiness of PD speech by listeners with different levels of familiarity with speech disorders in Dutch. We investigated assessments and classification accuracy differences between Dutch-speaking SLTs (n = 18) and Dutch/non-Dutch speaking untrained listeners (n = 27 and n = 124, respectively). We collected speech data from 30 Dutch speakers diagnosed with PD and 30 Dutch healthy controls. The stimuli set consisted of short phrases from spontaneous and read speech and of phrases produced with different sentence type intonation. Listeners participated in an online experiment targeting classification of sentence type intonation and perceived healthiness of speech. Results indicate that both familiarity with speech disorders and with speakers' language are significant and have different effects depending on the task type, as different listener groups demonstrate different classification accuracy. There is evidence that untrained Dutch listeners classify PD speech as unhealthy more accurately than both trained Dutch and untrained non-Dutch listeners, while trained Dutch listeners outperform the other two groups in sentence type classification.

Meta-Analysis
OBJECTIVE
To assess the effect of speech and language therapy (SLT) on Hypokinetic dysarthria (HD) in Parkinson's disease.
DESIGN
Systematic review and meta-analysis of randomized controlled trials.
METHODS
We performed a literature search of randomized controlled trials using PubMed, Web of Science, Science Direct and Cochrane database (last search October 2020). Quality assessment and risk of bias were assessed using the Downs and Black scale and the Cochrane tool. The data were pooled and a meta-analysis was completed for sound pressure levels, perceptual intelligibility and inflection of voice fundamental frequency.
RESULTS
We selected 15 high to moderate quality studies, which included 619 patients with Parkinson's disease. After pooling the data, 7 studies, which compared different speech language therapies to no treatment, control groups and 3 of their variables, (sound pressure level, semitone standard deviation and perceptual intelligibility) were included in the analysis.Results showed significant differences in favor of SLT for sound pressure level sustained phonation tasks (standard mean difference = 1.79; 95% confidence interval = 0.86, 2.72; ⩽ 0.0001). Significant results were also observed for sound pressure level and semitone standard deviation in reading tasks (standard mean difference = 1.32; 95% confidence interval = 1.03, 1.61; ⩽ 0.0001). Additionally, sound pressure levels in monologue tasks showed similar results when SLT was compared to other treatments (standard mean difference = 0.87; 95% confidence interval = 0.46, 1.28; ⩽ 0.0001).
CONCLUSION
This meta-analysis suggests a beneficial effect of SLT for reducing Hypokinetic Dysarthria in Parkinson's disease, improving perceptual intelligibility, sound pressure level and semitone standard deviation.

Review
Myasthenia gravis (MG) is an acquired autoimmune disease. Its clinical manifestations comprise ptosis, diplopia, dysarthria, dysphagia, limb weakness, and in severe cases, respiratory muscle involvement. Dysarthria as an exclusive initial and primary complaint in MG is rare and seldom reported. In this paper, we report a case of type IIIb MG with isolated dysarthria as the only clinical manifestation and we review the relevant literature. The patient was a 62-year-old man who presented with episodes of slurred speech for 20 days that had worsened in the previous 9 days. His medical history comprised hypertension, diabetes mellitus, and coronary heart disease. The initial diagnosis on admission was transient ischemic attack. Careful re-examination of the patient's history revealed that his symptoms mainly involved increasingly worse slurred speech episodes without drinking or swallowing difficulties, and no significant improvement with rest was observed. Electromyography and autoantibody profiling led to a diagnosis of type IIIb MG. His symptoms improved after the oral administration of pyridostigmine bromide 60 mg. Laryngeal MG is important to differentiate from stroke. It is necessary to perform a computerized voice analysis when encountering patients with atypical symptoms of MG.
