Methods: A search was conducted in the Scopus and PubMed databases in May of 2024. Eleven articles were obtained from the search. The standards of PRISMA recommendations were used for scoping reviews and the PCC framework was used for the eligibility criteria. Furthermore, the study used the instructions in the Cochrane Handbook for a quality assessment. The Mendeley Reference Manager software collected the studies and removed duplicates. Results: The reviewed studies employed formal and informal measures to assess voice and speech abilities in the children. Regarding the sample\u2019s characteristics, the studies mostly included children with Cerebral Palsy (CP) and also those with Down Syndrome (DS). All the studies reported that children with CP and DS undertook a total dose of the LSVT LOUD treatment. Significant post-treatment findings indicated increased speech function and sound pressure level, regarding the auditory\u2013perceptual ratings of voice and speech improvement. In many studies, parents\u2019 and expert listeners\u2019 ratings of voice, perception of vocal loudness, speech, and communication indicated improvement. Conclusions: The majority of the included studies provide positive evidence for the LSVT as an approach. However, the small sample size that featured in the studies, as well as their limitations, made these conclusions uncertain. Moreover, the study\u2019s findings provided recommendations that speech language therapists and other clinicians need to follow when setting a treatment plan with children with CP and DS.<\/jats:p>","DOI":"10.3390\/brainsci14090937","type":"journal-article","created":{"date-parts":[[2024,9,19]],"date-time":"2024-09-19T09:23:04Z","timestamp":1726737784000},"page":"937","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The Effectiveness of Lee Silverman Voice Treatment (LSVT LOUD) on Children\u2019s Speech and Voice: A Scoping Review"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9988-9273","authenticated-orcid":false,"given":"Angelos","family":"Papadopoulos","sequence":"first","affiliation":[{"name":"School of Health Rehabilitation Sciences, University of Patras, 26500 Patras, Greece"},{"name":"General Children\u2019s Hospital of Patras \u201cKaramandaneio\u201d, 26331 Patras, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3754-2466","authenticated-orcid":false,"given":"Louiza","family":"Voniati","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, Speech and Language Therapy, European University, Nicosia 22006, Cyprus"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5063-7312","authenticated-orcid":false,"given":"Nafsika","family":"Ziavra","sequence":"additional","affiliation":[{"name":"Department of Speech and Language Therapy, School of Health Sciences, University of Ioannina, GR45500 Ioannina, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7317-4106","authenticated-orcid":false,"given":"Dionysios","family":"Tafiadis","sequence":"additional","affiliation":[{"name":"Department of Speech and Language Therapy, School of Health Sciences, University of Ioannina, GR45500 Ioannina, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"348","DOI":"10.1016\/j.jvoice.2003.12.009","article-title":"Prevalence of voice disorders in African American and European American preschoolers","volume":"18","author":"Duff","year":"2004","journal-title":"J.
