Upper extremity amputees were tested on a standardized series of tasks using a myoelectric hand, a conventional prosthesis (cable-controlled hook), and their normal hand (unilateral amputees only). They answered also a questionnaire on activities of daily living (ADL) and provided other prosthetic information. Amputees who had been fitted only with a conventional prosthesis, and used their prosthesis regularly, tended to wear the prosthesis more hours per day (14 hours) than amputees fitted with a myoelectric hand (9.6 hours), some of whom continued to use a conventional prosthesis for some jobs. However, the amputees with myoelectric prostheses had a greater functional range of motion (ROM) than those with a conventional prosthesis, and many regular wearers of a myoelectric prosthesis had long since rejected a conventional prosthesis. Amputees took about 2.5 times as long to complete the tasks tested with a conventional prosthesis and about five times as long with a myoelectric prosthesis than with their normal hand. Despite the slower function, more than 60% of below-elbow (B-E) amputees accepted the myoelectric prosthesis in preference to a conventional prosthesis, which they had all been fitted with previously. Others preferred to continue using a conventional prosthesis to which they had become accustomed (13%) or no prosthesis (26%). The combination of function, ROM, and cosmetic appearance of a myoelectric prosthesis is preferred by most B-E amputees, despite its slower performance at the present time.
上肢截肢者使用肌电手、传统假肢（缆线控制钩）以及他们的正常手（仅针对单侧截肢者）进行了一系列标准化任务测试。他们还回答了一份关于日常生活活动（ADL）的问卷，并提供了其他假肢相关信息。仅安装了传统假肢且经常使用的截肢者，每天佩戴假肢的时间（14小时）往往比安装了肌电手的截肢者（9.6小时）更长，其中一些安装肌电手的截肢者在某些工作中仍继续使用传统假肢。然而，使用肌电假肢的截肢者比使用传统假肢的截肢者具有更大的功能活动范围（ROM），而且许多长期佩戴肌电假肢的人早已不再使用传统假肢。与使用正常手相比，截肢者使用传统假肢完成测试任务的时间大约是正常手的2.5倍，使用肌电假肢完成任务的时间大约是正常手的5倍。尽管功能较慢，但超过60%的肘下（B - E）截肢者更喜欢肌电假肢而非他们之前都安装过的传统假肢。其他人则更愿意继续使用他们已经习惯的传统假肢（13%）或不使用假肢（26%）。尽管目前肌电假肢的性能较慢，但大多数肘下截肢者还是更喜欢其功能、活动范围和外观的综合表现。
