The goal of this research is to study the dynamics of human posture on a balance board with tunable stiffness and time delay and exploit this understanding to improve the early detection of neuromuscular disease and the rehabilitation of balance compromised populations. The research will develop new mathematical models of human posture coupled to an external system and study the emergent dynamics therein; and develop a novel balance board with tunable board rotational stiffness and time delay. This tunable device will be used to assess the potential advantages of bifurcation-based approaches for the early detection of neuromuscular disorder and improved rehabilitation of younger subjects, older subjects and individuals with multiple sclerosis (MS), in collaboration with the Indiana University School of Medicine. In addition an inter-generational service-learning program focused on improving balance will be developed at a local retirement home, a campus wide forum/seminar series on dynamical systems in perception, cognition, and motor control will be created, senior undergraduate students will be mentored in research projects, and the team will reach out to local MS support groups.The development of the tunable balance board could be a major improvement in rehabilitative devices as it can manipulate and thus, explore the contribution of muscle stiffness and time delay to balance. If successful the idea of using bifurcation thresholds on the tunable balance boards as a means of indicating early stage neuromuscular disease could lead to early diagnosis of fall-propensity in frail older adults and adults with MS, Parkinson?s disease or persons suffering from traumatic brain injury. New detection and training concepts using these tunable balance boards delay could eventually be commercialized and improve quality of life of balance-compromised individuals. In addition, the substantial economic cost associated with falls, valued at over $19 billion in direct medical costs in 2000, may be reduced.

这项研究的目的是在平衡板上研究人类姿势的动态，并具有可调的僵硬和时间延迟，并利用这种理解来改善对神经肌肉疾病的早期发现以及对平衡受损人群的康复。该研究将开发出与外部系统相连的人类姿势的新数学模型，并研究其中的新兴动态。并开发一个具有可调板旋转刚度和时间延迟的新颖平衡板。这种可调装置将用于评估基于分叉的方法的潜在优势，以与印第安纳大学医学院合作，以早期检测神经肌肉疾病，改善了年轻受试者，年长受试者和患有多发性硬化症（MS）的人的康复。此外，将在当地的退休之家开发着一项宗旨宗教服务学习计划，校园广泛的论坛/研讨会系列有关感知，认知和运动控制的动态系统的系列系列，将在研究项目中受到高级本科生的指导，因此，团队将与MS的支持小组联系起来。探索肌肉刚度和时间延迟的贡献。如果成功的想法是在可调平衡板上使用分叉阈值作为表明早期神经肌肉疾病的一种手段，可能会导致早期诊断出患有女性疾病，帕金森氏病或患有创伤性脑损伤的人的脆弱的老年人和成年人。使用这些可调的平衡板延迟的新检测和培训概念最终可以商业化并改善平衡受损的人的生活质量。此外，与跌倒有关的大量经济成本可能会减少2000年的直接医疗费用超过190亿美元。
