There are few instruments available for evaluating functional mobility during multitasking in people with Parkinson’s Disease (PD). Virtual Reality is a potentially tool capable of aiding in the evaluation of functional mobility. The purpose of this study is to verify the potential of the Virtual Functional Mobility Test (VFMT) as a clinical tool to assess functional mobility of people with PD during multitasking condition. 25 people with PD and 25 people without PD, matched for age and sex, were recruited. Participants were evaluated through the Trail Making Test, Timed “UP and GO” test, Timed “UP and GO” test in dual task condition and through the VFMT, composed of 1) a simple task, and 2) a complex task. The VFMT and clinical tests were sensitive to differentiate the groups, except the trail making test part B (p = 0.332) and complex task (p = 0.052). Strong correlations were observed between parts A and B of the trail making test (r = 0.75) and complex task (r = 0.72); Moderate correlations between Timed Up and Go test and Timed Up and Go test in dual task condition with simple task (r = 0.47) and complex task (r = 0.55), respectively, were found. The complex task and simple task showed excellent and moderate reliability intra-rater, respectively. It was concluded that the novel VFMT is feasible, sensible, reliable and has potential as an instrument for the evaluation of functional mobility during multitasking in people with PD.

很少有工具可用于评估帕金森病 (PD) 患者在处理多项任务时的功能移动性。虚拟现实是一种能够帮助评估功能移动性的潜在工具。本研究的目的是验证虚拟功能移动性测试 (VFMT) 作为临床工具的潜力，以评估 PD 患者在多任务处理期间的功能移动性。招募了年龄和性别匹配的 25 名患有 PD 的人和 25 名未患有 PD 的人。通过 Trail Making Test、定时“UP and GO”测试、双任务条件下的定时“UP and GO”测试和 VFMT 对参与者进行评估，包括 1) 一个简单的任务，和 2) 一个复杂的任务。VFMT 和临床测试对区分组很敏感，除了试验 B 部分（p = 0. 332) 和复杂任务 (p = 0.052)。在试验测试的 A 和 B 部分（r = 0.75）和复杂任务（r = 0.72）之间观察到强相关性；分别在具有简单任务 (r = 0.47) 和复杂任务 (r = 0.55) 的双任务条件下，发现 Timed Up and Go 测试和 Timed Up and Go 测试之间存在中等相关性。复杂任务和简单任务分别显示出优秀和中等可靠性的内部评分者。得出的结论是，新型 VFMT 是可行的、明智的、可靠的，并且有潜力作为评估 PD 患者多任务处理期间功能移动性的工具。分别在具有简单任务 (r = 0.47) 和复杂任务 (r = 0.55) 的双任务条件下，发现 Timed Up and Go 测试和 Timed Up and Go 测试之间存在中等相关性。复杂任务和简单任务分别显示出优秀和中等可靠性的内部评分者。得出的结论是，新型 VFMT 是可行的、明智的、可靠的，并且有潜力作为评估 PD 患者多任务处理期间功能移动性的工具。分别在具有简单任务 (r = 0.47) 和复杂任务 (r = 0.55) 的双任务条件下，发现 Timed Up and Go 测试和 Timed Up and Go 测试之间存在中等相关性。复杂任务和简单任务分别显示出优秀和中等可靠性的内部评分者。得出的结论是，新型 VFMT 是可行的、明智的、可靠的，并且有潜力作为评估 PD 患者多任务处理期间功能移动性的工具。
