[Purpose] The aim of this study was to test the hypothesis that Lee Silverman Voice Treatment-BIG decreases the negative impact of hypokinesia on dual task performance in persons with Parkinson's disease. [Subjects and Methods] The records of 114 patients with Parkinson's admitted to outpatient rehabilitation at a suburban hospital were reviewed. Demographics and data for 8 outcome measures were extracted for subjects that completed 14 of 16 sessions of BIG. 93 of these subjects had records of pre and post-test Timed Up and Go, Timed Up and Go Motor, and Timed Up and Go Cognitive scores. Average age was 68.4 years (SD=10.6) and average disease duration was 4.9 years (SD=5.3). [Results] Subjects demonstrated statistically significant improvements for Timed Up and Go (3.3 SD=4.5), Timed Up and Go Motor (4.4 SD=5.8) and Timed Up and Go Cognitive (4.7 SD=5.4). Concurrent motor and cognitive performance remained stable. Dual task cost decreased at a statistically significant level for Timed Up and Go Cognitive (7% SD=31%) but not Motor (4% SD=32%). [Conclusion] These findings suggest that cueing strategies associated with LSVT BIG become internalized and decrease the negative impact of hypokinesia on mobility and cognitive performance while performing two tasks simultaneously in persons with Parkinson's.
[目的]本研究旨在验证以下假设：李·西尔弗曼嗓音治疗-大步法（Lee Silverman Voice Treatment-BIG）可降低运动功能减退对帕金森病患者双重任务表现的负面影响。[对象与方法]回顾了一家郊区医院门诊康复科收治的114例帕金森病患者的记录。提取了完成16节大步法治疗中14节治疗的受试者的人口统计学数据和8项结局指标的数据。其中93名受试者有计时起立行走测试前、后的记录，包括计时起立行走总分、计时起立行走运动分和计时起立行走认知分。平均年龄为68.4岁（标准差=10.6），平均病程为4.9年（标准差=5.3）。[结果]受试者在计时起立行走总分（改善3.3分，标准差=4.5）、计时起立行走运动分（改善4.4分，标准差=5.8）和计时起立行走认知分（改善4.7分，标准差=5.4）方面有统计学意义的改善。同时进行的运动和认知表现保持稳定。计时起立行走认知任务的双重任务成本在统计学显著水平上下降（7%，标准差=31%），但计时起立行走运动任务的双重任务成本未下降（4%，标准差=32%）。[结论]这些发现表明，与李·西尔弗曼嗓音治疗-大步法相关的提示策略被内化，并降低了运动功能减退对帕金森病患者同时执行两项任务时的移动能力和认知表现的负面影响。
