This case study measured how well the Lee Silverman Voice Treatment (LSVT) improved vocal features, intelligibility, and communicative effectiveness for a multilingual participant with hypokinetic-hyperkinetic dysarthria secondary to suspected progressive supranuclear palsy. LSVT treatment was chosen for the participant due to the strengths and deficits he presented with prior to treatment, and for the anticipated challenges in treatment that may arise from the presence of multilingualism and impaired cognitive functioning.
A multilingual patient in their 60's (English, Spanish, and French) with hypokinetic-hyperkinetic dysarthria secondary to suspected progressive supranuclear palsy completed the standard treatment sessions for LSVT. Assessment measures were taken at baseline, immediately post-treatment, and three-months post-treatment.
Improvements were measured in vocal quality, vocal loudness, intelligibility, and communicative effectiveness immediately post-treatment. Three months post-treatment, improvements in vocal quality and intelligibility were maintained.
This case study illustrates that LSVT may be a beneficial treatment for complex clients who are multilingual and present with complex comorbidities and cognitive deficits. LSVT resulted in some meaningful changes in vocal quality, intelligibility, and communicative effectiveness for this individual. Clinicians who work with complex patients may wish to consider the theoretical underpinnings of LSVT, client profile, areas of client need, and ability and desire to complete an intensive treatment program to determine if trialing LSVT is appropriate. The use of LSVT with complex clients may yield positive outcomes.
本案例研究评估了李·西尔弗曼嗓音治疗（LSVT）对一名疑似进行性核上性麻痹继发运动减少-运动增多型构音障碍的多语言参与者的嗓音特征、可懂度和沟通效果的改善程度。由于该参与者在治疗前表现出的优势和不足，以及考虑到多语言和认知功能受损可能给治疗带来的预期挑战，因此为其选择了LSVT治疗。
一名60多岁的多语言患者（会说英语、西班牙语和法语），因疑似进行性核上性麻痹继发运动减少-运动增多型构音障碍，完成了LSVT的标准治疗疗程。在基线、治疗后即刻和治疗后三个月进行评估测量。
治疗后即刻，嗓音质量、嗓音响度、可懂度和沟通效果均有改善。治疗后三个月，嗓音质量和可懂度的改善得以维持。
本案例研究表明，对于多语言且伴有复杂合并症和认知缺陷的复杂患者，LSVT可能是一种有益的治疗方法。LSVT使该个体在嗓音质量、可懂度和沟通效果方面产生了一些有意义的变化。治疗复杂患者的临床医生不妨考虑LSVT的理论基础、患者概况、患者需求领域，以及完成强化治疗计划的能力和意愿，以确定试用LSVT是否合适。对复杂患者使用LSVT可能会产生积极的效果。
