Benefits of intensive speech treatment have been documented for a range of speech signs in English speakers with Parkinson's Disease (PD). However, the answer to a critical question that whether the same treatment benefits speech variables including intelligibility in Mandarin speakers is still unclear. In order to develop a targeted speech treatment for Mandarin speakers with PD, we reviewed the efficacy of intensive speech treatment to improve vocal loudness and functional communication and discuss possible explanations for efficacy on Mandarin speakers with PD.
Literatures about intensive speech treatment for Mandarin speakers with PD were retrieved from PubMed, Web of Science, Embase, China National Knowledge Infrastructure (CNKI), Wanfang and Weipu Database for Chinese Technical Periodicals (VIP) Database. Search strategy was (voice therapy OR speech therapy OR voice treatment OR speech treatment OR voice training OR speech training OR voice rehabilitation OR speech rehabilitation OR Lee Silverman voice treatment OR intensive speech treatment) and (Parkinson's disease) and (Mandarin speakers OR Chinese OR Chinese people).
Five randomized controlled trials were selected and possible explanations for efficacy on individuals with PD are discussed. Further research directions are suggested.
The existing evidence from treatment efficacy studies of intensive speech treatment provides support for improving vocal loudness, speech intelligibility, pitch and rate in Mandarin speakers with PD. Our future research will continue to work to conduct a large sample multicenter randomized controlled trial to provide high quality evidence and understand the basic mechanisms accompanying treatment-related change.
强化语音治疗已被证明对英语帕金森病（PD）患者的多种语音症状有益。然而，对于一个关键问题的答案，即相同的治疗是否有益于普通话使用者的语音变量，包括可理解性，仍然不清楚。为了为普通话 PD 患者开发有针对性的语音治疗，我们回顾了强化语音治疗对提高嗓音响度和功能交流的疗效，并讨论了强化语音治疗对普通话 PD 患者疗效的可能解释。
从 PubMed、Web of Science、Embase、中国知网（CNKI）、万方和维普中文科技期刊数据库（VIP）数据库中检索了针对普通话 PD 患者的强化语音治疗文献。检索策略为（语音治疗或言语治疗或语音治疗或言语治疗或语音训练或言语训练或语音康复或言语康复或李西尔曼语音治疗或强化语音治疗）和（帕金森病）和（普通话使用者或中国人或中国人）。
选择了 5 项随机对照试验，并讨论了强化语音治疗对 PD 患者疗效的可能解释。提出了进一步的研究方向。
强化语音治疗疗效研究的现有证据为提高普通话 PD 患者的嗓音响度、言语可理解度、音调和语速提供了支持。我们未来的研究将继续努力进行大样本多中心随机对照试验，以提供高质量的证据，并了解伴随治疗相关变化的基本机制。
