目前，先进的电动假肢设备由残留肌肉产生的肌电信号控制，并通过皮肤上的表面电极进行记录。这些表面记录往往不一致和不可靠，导致上肢截肢患者的假体弃置率很高。表面电极由于皮肤接触不良、关节窝旋转、残肢出汗，以及它们只能记录来自浅表肌肉的信号的能力而受到限制，这些肌肉的功能往往与预期的假肢功能无关。更复杂的假肢装置要求使用者和机械手之间有一个稳定可靠的接口，以改善上肢假肢功能。植入式肌电传感器(IMES®)是一种小电极，用于检测EMG信号，并通过假肢插座中内置的电磁线圈将其无线传输到机电假手。该系统设计用于同时捕获来自多个残肢肌肉的肌电信号，允许同时自然控制多个自由度。我们报告了FDA批准的首个IMES®系统临床试验的情况。这项研究目前正在进行中，报告仅限于初步结果。我们的第一个受试者报告了与他以前的肌电假体相比，他在日常生活中完成更多种类和更复杂的任务的能力。这项研究的中期结果表明，利用IMES®技术可靠地感知并无线传输残馀肌肉的肌电信号，以直观地控制三自由度假肢是可行的。
Advanced motorized prosthetic devices are currently controlled by EMG signals generated by residual muscles and recorded by surface electrodes on the skin. These surface recordings are often inconsistent and unreliable, leading to high prosthetic abandonment rates for individuals with upper limb amputation. Surface electrodes are limited because of poor skin contact, socket rotation, residual limb sweating, and their ability to only record signals from superficial muscles, whose function frequently does not relate to the intended prosthetic function. More sophisticated prosthetic devices require a stable and reliable interface between the user and robotic hand to improve upper limb prosthetic function. Implantable Myoelectric Sensors (IMES®) are small electrodes intended to detect and wirelessly transmit EMG signals to an electromechanical prosthetic hand via an electromagnetic coil built into the prosthetic socket. This system is designed to simultaneously capture EMG signals from multiple residual limb muscles, allowing the natural control of multiple degrees of freedom simultaneously. We report the status of the first FDA-approved clinical trial of the IMES® System. This study is currently in progress, limiting reporting to only preliminary results. Our first subject has reported the ability to accomplish a greater variety and complexity of tasks in his everyday life compared to what could be achieved with his previous myoelectric prosthesis. The interim results of this study indicate the feasibility of utilizing IMES® technology to reliably sense and wirelessly transmit EMG signals from residual muscles to intuitively control a three degree-of-freedom prosthetic arm.
