作者之前开发了一种多握肌电控制器，并评估了健康受试者使用前臂前部和后部肌肉组织控制多握手假体配置的能力，这将代表经桡动脉截肢者群体使用的控制器。在本文中，作者进行了类似的研究，这一次，以评估能力的transshumeral截肢者控制多握手从残余的肌肉组织在上臂。具体而言，实验进行了5名健康受试者，比较他们的能力，以获得七个手的姿势之一，在一个虚拟的假肢从肌电图测量各自的二头肌和三头肌的肌肉组织。控制虚拟手假体的能力与他们用完整的手这样做的能力进行比较，如通过数据手套测量的。结果表明，在二头肌和三头肌上使用EMG控制器的平均过渡时间为1.86秒，而使用数据手套的平均过渡时间为0.82秒。
The authors have previously developed a multigrasp myoelectric controller, and assessed the ability of healthy subjects to control the configuration of a multigrasp hand prosthesis using musculature on the anterior and posterior aspects of the forearm, as would be representative of controller use by a transradial amputee population. In this paper, the authors conduct a similar study, this time to assess the capability of a transhumeral amputee to control a multigrasp hand from residual musculature on the upper arm. Specifically, experiments are conducted on five healthy subjects, comparing their ability to obtain one of seven hand postures in a virtual prosthesis from EMG measurement of the respective biceps and triceps musculature. The ability to control the virtual hand prosthesis is compared with their ability to do so with their intact hand, as measured by a dataglove. Results indicate an average transition time using the EMG controller on the biceps and triceps of 1.86 seconds, relative to 0.82 seconds with the dataglove.
