DESCRIPTION (provided by applicant): The purpose of this project is to implement myoelectric signals as a control source for an existing hand-grasp neuroprosthetic device. The current device uses a chest-mounted, shoulder position sensor. With the proposed device, control signals could be derived from weak myoelectric activity, making it possible for patients without sufficient shoulder mobility to use the neuroprosthesis. Myoelectric control is currently utilized in commercially available electromechanical prostheses. During the completed Phase I study, an electronic device was developed that records myoelectric signals and removes stimulation artifacts. A preliminary study was conducted with spinal-cord-injured and able-bodied subjects that demonstrated the feasibility of using myoelectric signals as a control source. During the proposed Phase II study, a pre-production device will be developed for myoelectric control of the neuroprosthesis. A clinical investigation will be conducted to demonstrate the utility of the myoelectric control system. The investigation participants will evaluate myoelectric control of their existing neuroprosthesis in daily use. It is anticipated that the participants will prefer myoelectric control due to improved durability, increased cosmetic appeal, and improved usability.

描述（由申请人提供）：本项目的目的是 实现肌电信号作为现有手抓握控制源 神经修复装置目前的设备使用胸部安装，肩膀 位置传感器利用所提出的装置，可以导出控制信号 从弱肌电活动，使患者有可能没有 足够的肩部活动度以使用神经假体。肌电控制是 目前用于市售的机电假体。 在已完成的I期研究期间，开发了一种电子设备， 记录肌电信号并去除刺激伪影。初步 一项研究是在脊髓损伤和身体健全的受试者中进行的， 证明了使用肌电信号作为控制源的可行性。 在拟议的第二阶段研究期间，将开发预生产设备 用于神经假体的肌电控制临床研究将 进行演示肌电控制系统的实用性。的 研究参与者将评估他们现有的肌电控制 日常使用的神经假体。预计与会者将 更喜欢肌电控制，因为耐用性更好，美观性更好 吸引力和改进的可用性。
