7. Project Summary/Abstract People with major upper limb amputation lose significant dexterity and function because the prosthetic devices that replace the lost limb contain fewer degrees of freedom than the physiological hand and lack sensory feedback. The development of multi-functional prosthetic hands has accelerated over the past two decades however none of the commercially available devices provide sensory feedback. The goal of this project is to design, develop, and test a prosthetic limb system which provides physiologically appropriate sensory feedback with a multi-functional prosthetic hand. In short, this project plans to recreate the sense of touch for persons with upper-limb amputation. Two hypotheses will be investigated. 1) Persons with limb loss using a prosthetic system including a myoelectric multi-DoF prosthetic hand and physiologically appropriate sensory feedback will significantly improve performance and learn quicker when performing activities of daily living compared to performing the same tasks without sensory feedback. 2) Persons feeling physiologically appropriate feedback when performing activities of daily living with a myoelectric multi-DoF prosthesis will experience an increased sensation of embodiment compared to persons not experiencing the sensory feedback. Three specific aims will be accomplished in order to answer the hypotheses. In specific aim 1, an advanced prosthetic limb system will be developed in order to test the hypotheses. This prosthesis will integrate the following technologies into a seamless, real-time prosthetic limb system: 1) surface electromyographic (EMG) sensors, 2) the myoelectric postural control algorithm, 3) the six DoF Bebionic prosthetic hand, 4) Numatac fingertip sensors (Syntouch LLC. Los Angeles, CA), and 5) FINE for stimulation of peripheral nerves and delivery of sensory feedback. In Specific Aim 2, tests of activities of daily living will be performed in order to quantify the functional improvements of the advanced prosthetic limb system with and without sensory feedback. Finally in Specific Aim 3, the prosthesis incorporation measure (PIC) and control bottleneck index (CBI) outcome measures will be used to quantify the embodiment experienced by the subjects. This project will dramatically improve prosthetic limb technology. Scientific knowledge and clinical practice with respect to persons with upper limb amputation will both be advanced. We believe this system could reduce the rejection rates of prosthetic users by improving their ability to perform functional tasks and thereby reduce comorbities such as cumulative trauma disorders in the sound-side limb. We also expect that this system will improve the quality of life in people with an amputation by reducing phantom limb pain and increasing the embodiment of the prosthesis. The cost in time and money due to phantom limb pain is a massive healthcare concern, and any method to reduce this burden would be a monumental achievement in the ability to provide better healthcare for Veterans and non-Veterans alike. The proposed collaboration is a unique opportunity within the VA health care system that can positively impact the clinical healthcare and rehabilitation of Veterans.

7.项目总结/摘要 由于假肢装置，上肢大截肢的人会失去显着的灵活性和功能 代替失去的肢体的手比生理手具有更少的自由度， 反馈在过去的二十年里，多功能假手的发展速度加快 然而，没有一种商业上可获得的装置提供感觉反馈。该项目的目标是 设计，开发和测试假肢系统，提供生理上适当的感觉 多功能假手的反馈。简而言之，这个项目计划重新创造触觉， 上肢截肢者。 将研究两个假设。1)使用假肢系统的肢体丧失者， 肌电多自由度假手和生理上适当的感觉反馈将显著地 提高性能和学习更快地进行日常生活活动相比，执行 没有感官反馈的相同任务。2)在以下情况下， 使用肌电多自由度假肢进行日常生活活动将增加 与没有经历感觉反馈的人相比，实施例的感觉。 为了回答这些假设，将实现三个具体目标。在具体目标1中， 为了验证这些假设，将研制假肢系统。这种假肢将整合 将以下技术整合到无缝、实时的假肢系统中：1）表面肌电（EMG） 传感器，2）肌电姿势控制算法，3）六自由度Bebionic假手，4）Numatac 指尖传感器（Syntouch LLC.洛杉矶，CA），和5）FINE用于刺激外周神经， 传递感官反馈。在具体目标2中，将进行日常生活活动测试，以便 量化先进假肢系统的功能改善， 反馈最后，在具体目标3中，假体纳入指标（PIC）和控制瓶颈指标 (CBI)结果测量将用于量化受试者经历的实施例。 该项目将极大地改善假肢技术。科学知识和临床实践， 对上肢截肢者的尊重将得到提高。我们相信这个系统可以减少 通过提高假肢使用者执行功能任务的能力， 合并症，如健全侧肢体的累积性创伤障碍。我们还希望，这一系统将 通过减少幻肢疼痛和增加截肢患者的生活质量， 假体的实施例。由于幻肢疼痛而花费的时间和金钱是一项巨大的医疗保健 任何减轻这种负担的方法都将是一项巨大的成就， 为退伍军人和非退伍军人提供更好的医疗保健。拟议的合作是一个独特的机会 在VA医疗保健系统中，可以积极影响临床医疗保健和康复， 老兵
