DESCRIPTION (provided by applicant): APDM is a young company focused on developing and commercializing professional systems using wearable inertial sensors for monitoring of human movement and movement disorders. In Phase I, we developed the novel, Instrumented Stand and Walk test (ISAW) using APDM's proprietary, Opal movement monitors and Mobility Lab system. We validated the ISAW by demonstrating that the ISAW measures were sensitive to severity of Parkinson's disease (PD) and levodopa treatment. The ISAW allows clinicians and nonexperts to quickly obtain objective measures of standing balance, step-initiation, gait, and turning. The ultimate goal for the product is to provide a quick, portable, clinical system to quickly and automatically obtain objective measures of balance and gait disorders to predict fall risk using body-worn sensors. This Phase II STTR proposal will expand the use of the ISAW from PD to elderly fallers. We will partner with the largest, longitudinal study of falls in elderl men, the Osteoporotic Fractures in Men Study (MrOS), to characterize balance and gait in 361 community-dwelling older men, and with the Oregon Center of Aging and Technology (ORCATECH) in 97 community-dwelling older women. This proposal will not only demonstrate the feasibility and usefulness of the ISAW to quickly quantify balance and gait for multicenter clinical trials, it will also develop a unique Fall Risk Report and provide the ISAW with normative values for the elderly. This 3-year study will have both a Clinical Research and a Technology Development Aim to prepare the ISAW to expand market penetration from research to clinical practice as an objective biomarker for fall risk and mobility disability. The impact of the ISAW wil be on clinicians interested in measuring fall risk in the elderly, including primary care physician, neurologists, geriatricians, rehabilitation professionals, assisted living facilities, hospitals an athletic trainers. The Specific Aims are: Aim I. Clinical Research: Develop a fall risk evaluation system for clinicians from the ISAW test (Milestone 1. Develop a Fall Risk Report and Milestone 2. Develop reference values for integrity of balance and gait across older ages). Aim II. Technology Development: Prepare the ISAW to be practical and attractive for clinical practice as well as clinical trials (Milestone 3. Mobility Exchange: Prepare data repository for multi-site clinical data collection from the ISAW test (Milestone 4. Mobility Clinic: Simplify user-interface and reporting for clinicians, and Milestone 5. FDA: Put quality systems and regulatory compliance in place so ISAW can be marketed for clinical practice). This Phase II proposal will transform APDM's ISAW protocol into the first technological system for clinicians (Mobility Clinic) and clinical researchers (Mobility Lab) to provide a validated, objective fall risk evaluation, as well as comprehensive balance and gait disorder assessment.

描述(申请人提供)：APDM是一家年轻的公司，专注于开发和商业化使用可穿戴惯性传感器监测人体运动和运动障碍的专业系统。在第一阶段，我们使用APDM专有的Opal运动监测器和移动实验室系统开发了新颖的仪表式站立和行走测试(ISAW)。我们通过证明ISAW措施对帕金森病(PD)和左旋多巴治疗的严重程度敏感来验证ISAW。ISAW允许临床医生和非专家快速获得站立平衡、步态启动、步态和转身的客观测量。该产品的最终目标是提供一种快速、便携的临床系统，利用身体佩戴的传感器快速、自动地获得平衡和步态障碍的客观测量，以预测跌倒风险。这项第二阶段的短期租约建议，将会把ISAW的使用范围由帕金森病扩展至老年跌倒者。我们将与最大的关于老年男性跌倒的纵向研究，男性骨质疏松性骨折研究(MROS)合作，以确定361名社区居住的老年男性的平衡和步态特征，并与俄勒冈州老龄化与技术中心(ORCATECH)合作，研究97名社区居住的老年女性的平衡和步态。这项建议不仅将证明ISAW在多中心临床试验中快速量化平衡和步态的可行性和有用性，它还将制定独特的跌倒风险报告，并为ISAW提供规范的 老年人的价值观。这项为期3年的研究将以临床研究和技术开发为目标，为ISAW做好准备，将市场渗透率从研究扩大到临床实践，作为跌倒风险和行动不便的客观生物标记物。ISAW将对有兴趣测量老年人跌倒风险的临床医生产生影响，包括初级保健医生、神经科医生、老年医生、康复专业人员、辅助生活设施、医院和运动教练员。具体目标是：目标1.临床研究：根据ISAW测试为临床医生开发跌倒风险评估系统(里程碑1.制定跌倒风险报告和里程碑2.制定老年人平衡和步态完整性的参考值)。目的II.技术开发：使ISAW具有实用性和临床试验的吸引力(里程碑3.移动性交换：为从ISAW测试中收集的多点临床数据准备数据储存库(里程碑4.移动诊所：简化临床医生的用户界面和报告，里程碑5.FDA：建立质量体系和法规遵从性，以便ISAW可用于临床实践)。这项第二阶段的提案将把APDM的ISAW协议转变为临床医生(移动诊所)和临床研究人员(移动实验室)的第一个技术系统，以提供经过验证的、客观的跌倒风险评估，以及全面的平衡和步态障碍评估。
