DESCRIPTION (provided by applicant): The objective is to design, build, and clinically assess ParkinTune?, an advanced wireless movement disorder monitor technology to augment stimulation programming (tuning) involved in deep brain stimulation (DBS) procedures for Parkinson's Disease (PD). Major PD symptoms that affect quality of life include tremor, bradykinesia, and rigidity. While the exact mechanism that fuels DBS clinical success stories remains unclear, the procedure has been shown to effectively relieve PD motor symptoms when medication is no longer effective. However, clinicians lack tools that combine physiological, electrical, and behavioral data to optimize electrode placement and stimulator programming. Optimizing electrode placement and stimulator parameters improves the amount of motor symptom reduction patients receive and minimizes complications. The current standard in evaluating symptoms is the Unified Parkinson's Disease Rating Scale (UPDRS), a qualitative ranking system. A battery of exercises, typically a subset of the upper extremity motor section of the UPDRS, is normally completed during DBS electrode placement surgery and subsequent programming sessions to evaluate performance while a clinician qualitatively assesses symptoms. CleveMed has previously developed a compact wireless system to quantify movement disorder symptoms called ParkinSense?. This previously existing technology will serve as the hardware platform for this proposed program. While previous work has shown excellent results to objectively quantify symptoms during a clinical exam, this proposed project will integrate several new features for real-time assistance with DBS surgery electrode placement and stimulation programming. The clinically deployable ParkinTune system resulting from this proposed Fast-Track application will provide a compact wireless system for use in the operating room and outpatient follow up programming sessions that maximizes patient safety and comfort. The objective biokinetic data transmitted during electrode placement and subsequent programming will be input to algorithms that output a continuous scale of objective PD symptom severity in real-time to guide clinician decision making. The improved resolution and repeatable results of the ParkinTune system should reduce time and costs of DBS procedures as well as optimize patient outcomes.

描述（由申请人提供）：目标是设计、构建和临床评估ParkinTune？一种先进的无线运动障碍监测技术，用于增强刺激编程（调谐），涉及帕金森病（PD）的深部脑刺激（DBS）程序。影响生活质量的PD主要症状包括震颤、运动迟缓和僵硬。虽然推动DBS临床成功的确切机制尚不清楚，但该程序已被证明在药物不再有效时有效缓解PD运动症状。然而，临床医生缺乏结合生理、电和行为数据来优化电极放置和刺激器编程的工具。优化电极放置和刺激器参数提高运动症状减少患者接受的数量，并最大限度地减少并发症。目前评估症状的标准是统一帕金森病评定量表（UPDRS），这是一种定性排名系统。通常在DBS电极放置手术和随后的编程过程中完成一系列练习，通常是UPDRS上肢运动部分的一个子集，以评估表现，同时临床医生定性评估症状。CleveMed此前开发了一种名为ParkinSense的紧凑型无线系统，用于量化运动障碍症状。这种先前存在的技术将作为该计划的硬件平台。虽然先前的工作在临床检查中客观量化症状方面取得了出色的成果，但该项目将整合几个新功能，以实时辅助DBS手术电极放置和刺激规划。临床部署的ParkinTune系统由这个拟议的快速通道应用程序产生，将提供一个紧凑的无线系统，用于手术室和门诊随访编程会议，最大限度地提高患者的安全性和舒适度。在电极放置和随后的编程过程中传输的客观生物动力学数据将被输入到算法中，该算法实时输出连续的客观PD症状严重程度量表，以指导临床医生决策。ParkinTune系统改进的分辨率和可重复的结果将减少DBS手术的时间和成本，并优化患者的预后。
