Background: Hypernasality is a common feature of non-progressive dysarthria. However, limited research has investigated the effectiveness of treatments for this impairment. Preliminary research has revealed positive effects on nasalance when using increased loudness in certain non-progressive dysarthric speakers. However, the long-term effects of loud speech on nasalance as part of a structured intervention such as Lee Silverman Voice Treatment (LSVT)[R] are yet to be investigated in this population. Aims: The study aimed to investigate the short- and long-term effects of LSVT[R] on hypernasality (perceptual ratings and degree of nasalance) in non-progressive dysarthria; and secondly, to evaluate the effects of traditional dysarthria therapy on these same measures, in comparison with the effects of LSVT[R]. Methods & Procedures: Ten non-progressive dysarthric speakers with varying levels of hypernasality (taken from a larger research study) were randomly allocated to receive LSVT[R] (n = 5) or individually tailored traditional dysarthria therapy (n = 5). Both treatments were administered four times weekly for 4 weeks (that is, 16 x 1-hour sessions). Participants were assessed twice before treatment, twice immediately post-treatment, and twice at follow-up 6 months post-treatment using a perceptual rating task performed by two independent speech pathologists, and the Nasometer. Changes to individual mean nasalance scores were compared against clinically significant criterion and perceptual ratings were analysed descriptively. Outcomes & Results: Three out of five participants demonstrated reductions in perceived hypernasality immediately following LSVT[R], but these changes were maintained at follow-up for only one participant. Two of these three participants demonstrated a corresponding reduction in mean nasalance. Limited changes in perceived hypernasality and nasalance scores were found following traditional dysarthria therapy, with only one participant exhibiting reduced nasalance at follow-up. Conclusions & Implications: Due to the small sample size in the present research and variability between participants, further exploration into the effects of LSVT[R] on nasality with a larger population with different dysarthria types is essential.

This review aimed to evaluate the evidence for group therapy in improving speech production in adults with acquired dysarthria. Secondary outcomes included communication effectiveness and/or wellbeing. A review protocol was prospectively published on PROSPERO. Fourteen electronic databases were searched to identify experimental studies investigating adults with acquired dysarthria participating in group intervention with outcomes related to communication and/or wellbeing. The quality of included studies was assessed using the Mixed Methods Appraisal Tool (MMAT) or the McMaster University's Critical Review Form, and the TIDieR template for intervention description and replication. 21 studies were identified involving 330 individuals with dysarthria, from mostly Parkinson's disease (PD) (97%; n = 321). Treatment approaches included singing therapy (n = 10), loudness therapy (n = 5) and multi-components therapy (including a combination of impairment and/or compensatory approaches) (n = 4). Studies varied in intensity and outcome measures used. Statistically significant improvements to speech production and/or wellbeing were reported following most approaches. There is some preliminary moderate-quality evidence to suggest that group therapy may improve speech production and in some cases communication effectiveness or wellbeing in people with dysarthria following PD, with more consistent improvements being found for loudness approaches. Singing approaches were frequently studied in PD with some improvements to intelligibility evident. Further well-designed controlled studies including individuals with non-progressive aetiologies is warranted to establish the effectiveness of group treatment. Group therapy may be an effective means of improving speech production and/or wellbeing in individuals with dysarthria following Parkinson's disease. Studies' employing loudness-based group therapy for PD demonstrated more consistent improvements to intensity measures. Some controlled studies utilising singing group therapy resulted in improved intelligibility in PD. PROSPERO registration number: CRD42015029374. [ABSTRACT FROM AUTHOR]

To date, little research has explored clinical assessment practices in the management of dysarthria. The aim of the present study was to explore the practices and perspectives of Australian speech-language pathologists (SLPs) regarding outcome measures (OMs) in the management of dysarthria, including barriers and enablers to their use. A focus group methodology was used to explore the practices and perspectives of 16 SLPs working with adults with dysarthria. The 4 focus groups were transcribed and analysed using qualitative content analysis with barriers and enablers to the use of OMs analysed according to the Theoretical Domains Framework. Seven categories were identified regarding SLPs' practices and perspectives on the use of OMs in dysarthria management. These were related to the importance of assessments, OMs currently and not currently being utilised, ideal assessment features, perspectives on the development of a core set of OMs in dysarthria management, and perceived enablers and barriers to the use of OMs. Each category had a number of constituent subcategories. Overarching the categories was the theme: the who, why, when, where, what and how of dysarthria outcome measurement. The use of OMs in dysarthria is influenced by a range of factors including: the clinical setting, patient factors, and where and when the patient is in their recovery journey. Variability in the assessments used suggests that formal measures may not meet current clinical needs. [ABSTRACT FROM AUTHOR]
