Speech and Language Therapy for Voice Problems in Parkinson's Disease: A Meta-Analysis. J Neuropsychiatry Clin Neurosci. 2020 May 06;:appineuropsych19020044 Authors: Xu H, Bao Z, Liang D, Li M, Wei M, Ge X, Liu J, Li J Abstract Patients with Parkinson's disease (PD) commonly have speech and voice problems that affect their functional communication and that are not sensitive to pharmacological or neurosurgical treatments. The authors aimed to evaluate the effects of speech and language therapies (SLTs) on dysphonia in patients with PD by analyzing data from published randomized controlled trials (RCTs). Studies in English and Chinese that were related to speech and language treatment for patients with PD were retrieved from PubMed, Embase, Chinese National Knowledge Infrastructure, China Science and Technology Journal Database, Chinese Biomedical Literature Database, and Wanfang Database. On the basis of exclusion criteria, 391 records identified through the search were reduced to 10 studies that included 230 patients in the treatment groups and 205 patients in the control groups. A meta-analysis of data from the 10 studies was performed to examine the effects of SLTs on dysphonia in patients with PD.
