截肢者对肌电控制算法的功能评估促进了假肢设计领域的总体目标：替代失去的东西。然而，许多研究使用具有虚拟界面和健全受试者的实验范式，但没有捕捉到截肢人群临床实施的挑战。肌电控制系统必须对可变的生理学、假肢对肢体的负载效应以及动态任务期间的肢体位置效应具有鲁棒性。在这里，患有经桡动脉肢体丧失的人使用姿势控制器和多功能假手进行日常生活活动，以验证姿势控制器对这些临床挑战是否稳健。南安普顿手部评估程序是由肢体丧失者和身体健全的受试者进行的。结果表明，肢体丧失者和肢体健全的受试者取得了相同的表现，因此克服了临床挑战。肢体丧失者的手部生理功能平均达到 55%。此外，还将姿势控制器与之前测试的其他最先进的肌电控制器和假手进行了比较。这项工作证实了姿势控制器可能是一种临床上可行的控制肌电多功能假手的方法。
The functional assessment of myoelectric control algorithms by persons with amputation promotes the overarching goal of the field of prosthetic limb design: to replace what was lost. However, many studies use experimental paradigms with virtual interfaces and able-bodied subjects that do not capture the challenges of a clinical implementation with an amputee population. A myoelectric control system must be robust to variable physiology, loading effects of the prosthesis on the limb, and limb position effects during dynamic tasks. Here persons with transradial limb loss performed activities of daily living using a postural controller and multi-functional prosthetic hand in order to verify that the postural controller was robust to these clinical challenges. The Southampton Hand Assessment Procedure was performed by persons with limb loss and able-bodied subjects. The results indicate that persons with limb loss and able-limbed subjects achieved the same performance and therefore that the clinical challenges were overcome. Persons with limb loss achieved 55% of physiological hand function on average. Also, the postural controller is compared to other state of the art myoelectric controllers and prosthetic hands previously tested. This work confirms that the postural controller is potentially a clinically-viable method to control myoelectric multi-functional prosthetic hands.
