项目摘要

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（FOG）的冻结影响了大约一百万个在全国患有帕金森氏病的人中，大多数人都会停止运动，而患者将运动形容得像“脚粘在地面上”一样。雾通常发生在帕金森氏病的成熟阶段，导致平衡失去和严重跌倒。这些跌倒通常会造成严重的伤害，甚至在老年人中死亡。拟议的项目解决方案是通过确保步态期间适当使用步行者，并治疗当帕金森氏病使用滚动步行者时可能发生的冻结发作，以提高这种脆弱患者人群的步行安全性。依靠滚动步行者以保持平衡和支持并且不适当使用设备的个人会增加跌倒的风险。当个人从冻结的开始阶段陷入“向前”的姿势并且无法纠正自己时，可以将步行者推到身体远处，从而导致跌倒。提议的I期研究设备将通过使用监控身体位置的红外距离传感器以及向用户提供的感觉反馈以纠正其姿势，从而准确有效地检测出冻结并打破其完整发作。我们还将与潜在用户进行试验，以确定设备在防止雾发作中的有效性，从而防止使人衰弱。预期的结果是能够准确检测到冻结发作的设备（忽略误报），然后提供感官提示，以打破冻结的全部发作。几个合格的人组成了研究团队，包括Pi Shawn George，生物医学工程师兼概念证明设备的发明者；理查德·戈德堡（Richard Goldberg）博士，辅助技术和医疗工具开发专家；物理治疗师Linda Cates拥有20年的物理治疗师经验，并通过美国物理治疗协会是董事会认证的神经临床专家；和凯文（Kevin）洞穴，我，ATP，RET，在设计，开发，处方，提供和培训辅助技术方面拥有20多年的经验，以供各种残疾人进行辅助技术。公共卫生相关性：独立流动性的丧失是一般解释的关键指标，导致其他功能下降。迁移率的丧失已被证明可以预测老年人死亡率的增加。提出的装置将帮助残疾人维持流动性并降低死亡率。
