DESCRIPTION (provided by applicant): Freezing of Gait (FOG) effects the majority of the approximately one million individuals who have Parkinson's disease nationwide and causes a cessation of movement that patients describe as feeling as if their "feet are glued to the ground". FOG most often occurs in the mature stages of Parkinson's disease and results in a loss of balance and severe falls. These falls often cause serious injury or even death in elderly individuals. The proposed project solution is to improve walking safety for this vulnerable patient population by ensuring appropriate use of a walker during gait, and treating freezing episodes that can occur when an individual with Parkinson's disease uses a rolling walker. Individuals who rely on a rolling walker for balance and support and do not use the device appropriately are at an increased risk for falls. When the individual gets into a "forward-leaning" posture from the beginning stages of a freeze and is unable to right their self, the walker can be pushed farther away from the body, resulting in a fall. The proposed device for Phase I research will accurately and effectively detect a freeze and break its full onset, via the use of infrared distance sensors that monitor body position, and sensory feedback provided to the user to correct their posture. We will also perform trials with potential users to determine device effectiveness in preventing FOG episodes and thus preventing debilitating falls. The expected result is a device able to accurately detect a freezing episode (ignoring false positives), and then provide sensory cues that break the full onset of the freeze. Several well-qualified individuals make up the research team, including PI Shawn George, biomedical engineer and inventor of the proof-of-concept device; Dr. Richard Goldberg, an expert in the development of assistive technology and medical instrumentation; physical therapist Linda Cates, who has 20 years of experience as physical therapist and is a Board Certified Neurlogical Clinical Specialist through the American Physical Therapy Association; and Kevin Caves, ME, ATP, RET, who has 20+ years experience in the design, development, prescription, provision and training of assistive technology for people with a variety of disabilities. PUBLIC HEALTH RELEVANCE: The loss of independent mobility is a key indicator in general de-conditioning leading to other functional declines. Loss of mobility has been shown to be predictive of increased mortality in older adults. The proposed device will help individuals with disability to maintain mobility and decrease mortality.

描述（由申请人提供）：步态冻结（FOG）影响了全国大约100万帕金森病患者中的大多数人，并导致运动停止，患者描述为感觉好像他们的“脚粘在地上”。FOG最常发生在帕金森病的成熟阶段，导致失去平衡和严重跌倒。这些跌落通常会对老年人造成严重伤害甚至死亡。提出的项目解决方案是通过确保在步态中适当使用助行器，并治疗帕金森病患者使用滚动助行器时可能发生的冻结发作，从而提高弱势患者群体的步行安全性。依靠滚动助行器来保持平衡和支撑，并且没有正确使用该设备的人摔倒的风险会增加。当一个人从冻结的开始阶段进入一个“前倾”的姿势，无法纠正自己，步行者可能会被推得离身体更远，导致摔倒。第一阶段研究的拟议设备将通过使用红外距离传感器监测身体位置，并向用户提供感官反馈以纠正他们的姿势，准确有效地检测冻结并打破其全面发作。我们还将对潜在用户进行试验，以确定设备在预防FOG发作方面的有效性，从而防止使人衰弱的跌倒。预期的结果是一个设备能够准确地检测到冻结事件（忽略误报），然后提供感官线索，打破冻结的全面发作。研究团队中有几位非常有资格的人，包括生物医学工程师、概念验证设备的发明者PI·肖恩·乔治；辅助技术和医疗器械开发专家Richard Goldberg博士；物理治疗师Linda Cates，她拥有20年的物理治疗师经验，是美国物理治疗协会认证的神经临床专家；Kevin Caves， ME， ATP， RET，他在为各种残疾人士设计，开发，处方，提供和培训辅助技术方面拥有20多年的经验。
