Wireless Enhanced Myoelectric Control to Improve Upper Extremity Amputee Ability

描述(申请人提供)：无线增强肌电控制，以提高上肢截肢者的能力摘要我们研究计划的总体目标是使上肢截肢者能够多产和独立。对于这些人来说，过去十年最有希望的发展之一是引入了完全灵活的终端设备。然而，有效和直观的控制策略仍然难以捉摸。肌电控制对于一个或两个自由度的设备很有效，但在处理大量运动类别时无效(例如，当试图区分“手张开”、“食指指尖”、“精细捏”等时)。因此，需要一种战略，使截肢者能够实现非常高自由度的手控制，达到他们能够完成日常生活和工作的复杂任务的水平。我们现在建议开发和验证Morph2.0，肌电操作的RFID假手。Morph2.0基于我们的开创性和获奖概念，即通过基于射频识别(RFID)标签的策略来增强传统的肌电(EMG)控制方法。Morph技术显著增强了手以直观方式操纵对象和任务的能力：通过检测特定于对象的RFID标签，Morph通过在正确的时间可靠地给予截肢者正确的握力来增强截肢者的能力。RFID标签充当假手的输入，允许模式的自动和即时转换。具体地说，Morph2.0的设计目的是：1)通过提供对假体的更好控制来增强用户的能力，2)提高假体的可靠性，3)增加用户可以随时使用的手柄和操作模式的库存，以及4)执行许多日常灵活的功能任务。在这项快速通道的努力中，我们建议：1)创建和验证Morph2.0，2)第三方验证和确认Morph2.0，以及3)在一项针对横径截肢者的长期临床研究中对Morph2.0进行评估。我们的目标是部署RFID加强型假肢，并展示基于增强型肌电的控制方法，作为每个患者的最佳个性化解决方案。我们雄心勃勃但令人信服的目标是使截肢者能够独立生活，并提高他们的工作效率。

DESCRIPTION (provided by applicant): Wireless Enhanced Myoelectric Control to Improve Upper Extremity Amputee Ability ABSTRACT The overall goal of our research program is to enable upper extremity amputees to be productive and independent. For these individuals, one of the most promising developments in the past decade has been the introduction of fully dexterous terminal devices. However, an effective and intuitive control strategy has remained elusive. Myoelectric control works well for one or two degree-of-freedom devices, but is not effective when dealing with a large number of movement classes (such as when attempting to discriminate amongst "hand open", "index finger point", "fine pinch", and so on). Thus there is a need for a strategy to allow amputees to achieve a very high degree-of-freedom hand control, to the level that they can accomplish complex tasks of daily living and working. We now propose the development and validation of morph2.0, the Myoelectrically-Operated RFID Prosthetic Hand. morph2.0 is based on our pioneering and award-winning concept of augmenting traditional electromyogram (EMG) control methodology with a radio-frequency identification (RFID) tag based strategy. The morph technology significantly enhances the capability of the hand to manipulate objects and tasks in an intuitive way: by detecting object-specific RFID tags, morph empowers amputees by reliably giving them the right grip at the right time. The RFID tags act as inputs for the prosthetic hand, allowing automatic and immediate shifts in modes. Specifically, morph2.0 is designed to: 1) empower the user by providing greater control over the prosthesis, 2) increase reliability of the prosthesis 3) increase the inventory of grips and modes of operation the user can readily access, and 4) carry out numerous daily dexterous functional tasks. In this Fast Track effort, we propose: 1) the creation and verification of morph2.0, 2) the third party verification and validation of morph2.0 and 3) an evaluation of morph2.0 in a long-term clinical study of trans-radial amputees. It is our goal to deploy RFID-augmented prostheses and to demonstrate the augmented EMG based control methodologies as the best individualized solution for each patient. Our ambitious but compelling goal is to enable amputees' independent living and enhance their productivity at work.
