A survey of speech-language pathology treatment for non-progressive dysarthria in Australia

Abstract Aim: To identify management practices of Australian speech-language pathologists (SLPs) in the treatment of non-progressive dysarthria using a subsystem approach, and to explore SLPs’ consideration and implementation of the theoretical underpinnings of non-progressive dysarthria management. Method: A 39-item online survey was distributed to Australian SLPs, with 80 responses suitable for data analysis. Results: Practices of SLPs were variable for the management of the speech subsystems. The Lee Silverman Voice Treatment (LSVT®) was the most commonly used manualised treatment program, and was employed by 63.77% of respondents. Almost all SLPs (>88%) provided strategies to improve functional communication. There was no clear preference for low tech alternative and augmentative communication (AAC) devices. Speech generating devices were the most commonly employed high tech device. Almost two-thirds of respondents used non-speech oral motor exercises (NSOMEs) in treatment. SLPs had varied frequencies and models of service delivery for intervention. SLPs valued interventions targeting the activity and participation domains of the ICF, however this was restricted by the treatment context and resources available. The majority of SLPs (92.06%) were aware of the principles of motor learning, however many were unsure regarding the specifics of implementation. Conclusion: There is a clear need for further research into the efficacy of treatment techniques to guide decision-making.
