Neurodegenerative dysarthria: Respiratory/phonatory (Perry et al., 2024)

dataset
posted on 2024-01-17, 18:56 authored by Sarah E. Perry, Michelle S. Troche, Jessica E. Huber, James A. Curtis, Brianna R. Kiefer, Jordanna S. Sevitz, Qiana Dennard, James C. Borders, Jillian River Browy, Avery E. Dakin, Victoria Gonzalez, Julianna Chapman, Tiffany Wu, Lily Katz, Deanna Britton

Purpose: This systematic review represents an update to previous reviews of the literature addressing behavioral management of respiratory/phonatory dysfunction in individuals with dysarthria due to neurodegenerative disease.

Method: Multiple electronic database searches and hand searches of prominent speech-language pathology journals were conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards.

Results: The search yielded 1,525 articles, from which 88 met inclusion criteria and were reviewed by two blinded co-investigators. A large range of therapeutic approaches have been added to the evidence base since the last review, including expiratory muscle strength training, singing, and computer- and device-driven programs, as well as a variety of treatment modalities, including teletherapy. Evidence for treatment in several different population groups—including cerebellar ataxia, myotonic dystrophy, autosomal recessive spastic ataxia of Charlevoix–Saguenay, Huntington’s disease, multiple system atrophy, and Lewy body dementia—were added to the current review. Synthesis of evidence quality provided strong evidence in support of only one behavioral intervention: Lee Silverman Voice Treatment Program (LSVT LOUD) in people with Parkinson’s disease. No other treatment approach or population included in this review demonstrated more than limited evidence, reflecting that these approaches/populations require urgent further examination.

Conclusion: Suggestions about where future research efforts could be significantly strengthened and how clinicians can apply research findings to their practice are provided.
