项目摘要
DESCRIPTION (provided by applicant): Pattern recognition (PR) myoelectric control systems can dramatically improve an amputee patient's control over a powered prostheses, but they have not been made commercially available. Coapt, LLC, is a start-up stage company that is seeking to commercialize PR myoelectric control for the benefit of upper-limb amputees. The controller is based on research completed by the Rehabilitation Institute of Chicago's Center for Bionic Medicine. Numerous challenges, including clinically viable training and recalibration routines, have been overcame within the past decade, yet some still remain. One such challenge is to lower the power requirements of an embedded PR control system to an acceptable level such that the controller does not quickly drain the onboard prosthesis battery. The objective of this application is to lower the power requirements of the PR embedded control system such that it uses less than 10% of the battery's energy over a full day's use. Energy reduction is a critical item in the development of embedded control systems as it is directly related to the weight of the battery which must be attached to the prosthesis and carried by the patient whenever wearing the device. We will demonstrate the technical feasibility of the approach by the following two specific aims: (1) Develop power management algorithms to minimize power consumption of our pattern recognition controller in a manner that is transparent to the user, (2) Implement the power management techniques on the firmware of our pattern recognition controller. It is very important that our power management act in a manner that is transparent to the user. They must allow the overall control system to remain responsive to the user's command, even after long periods during which the system remains dormant. The proposed research is significant because it removes one of the few remaining clinical barriers preventing pattern recognition-based myoelectric control from being adopted. Ultimately, this research will help allow thousands of upper limb amputees to dramatically improve the control their prostheses, allowing for an improved quality of life.
描述(由申请人提供):模式识别(PR)肌电控制系统可以显着改善截肢者对载体假体的控制,但尚未商业上可用。 Coapt,LLC是一家启动舞台公司,正在旨在将PR肌电控制商业化,以使上limb amuputees受益。该控制者基于芝加哥仿生医学中心康复研究所完成的研究。在过去的十年中,包括临床上可行的培训和重新校准常规在内的许多挑战已经被克服了,但仍然存在一些挑战。一个挑战是将嵌入式PR控制系统的功率要求降低到可接受的水平,以使控制器不会迅速排出船上假体电池。该应用程序的目的是降低PR嵌入式控制系统的功率要求,以便在全天使用中使用电池能量的10%。减少能量是嵌入式控制系统开发的关键项目,因为它与电池的重量直接相关,该电池的重量必须固定在假体上并在佩戴设备时由患者携带。我们将通过以下两个具体目的来证明该方法的技术可行性:(1)开发电源管理算法以对用户透明的方式最大程度地减少我们的模式识别控制器的功率消耗,(2)在我们的模式识别控制器的固件上实施电源管理技术。我们的电力管理以对用户透明的方式行动非常重要。他们必须允许整体控制系统对用户的命令保持响应,即使在该系统处于休眠状态之后。拟议的研究之所以重要,是因为它消除了剩下的少数临床障碍之一,以防止采用基于模式识别的肌电控制。最终,这项研究将有助于使成千上万的上肢截肢者显着改善其假体的控制,从而改善生活质量。
