Mechanical properties of the DEKA Arm and associated engineering innovations are easy to observe. What is less clear is how these advances translate into functional benefits for the user with amputation. Study aims were to (1) quantify outcomes including dexterity, performance of daily activities, and prosthetic skill and spontaneity of users of the DEKA Arm and (2) compare outcomes when using the DEKA Arm with scores using the existing prosthesis. This was a quasi-experimental study. Descriptive analyses examined outcomes by DEKA Arm configuration level. Of the 39 subjects fit with a DEKA Arm, 32 were trained in use and completed end-of-study testing. Data from 26 prosthetic users were used to compare outcomes using existing prostheses with outcomes with the DEKA Arm. Dexterity and activity performance with the DEKA Arm varied by amputation level (p < 0.01). Self-reported function and number of activities performed using the prosthesis were similar across levels. Comparisons with existing prostheses showed the effect on dexterity varied by level. Activity performance and spontaneity of prosthetic use improved for users of the shoulder configuration level, while use of the prosthesis to perform activities and perceived difficulty performing self-selected tasks improved for all levels.
DEKA 上肢假肢的机械性能及相关工程创新成果易于观察。然而，这些进展如何转化为对截肢用户的功能益处，却不太明确。研究目的是：（1）量化包括灵活性、日常活动表现、假肢使用技能以及 DEKA 上肢假肢用户的自发性等结果；（2）将使用 DEKA 上肢假肢时的结果与使用现有假肢时的得分进行比较。这是一项准实验研究。描述性分析按 DEKA 上肢假肢配置水平对结果进行了检验。在 39 名适配 DEKA 上肢假肢的受试者中，32 人接受了使用培训并完成了研究结束时的测试。来自 26 名假肢用户的数据用于比较使用现有假肢与使用 DEKA 上肢假肢的结果。DEKA 上肢假肢的灵活性和活动表现因截肢水平而异（p < 0.01）。不同水平的自我报告功能和使用假肢进行的活动数量相似。与现有假肢的比较表明，对灵活性的影响因水平而异。肩部配置水平的用户在假肢使用的活动表现和自发性方面有所改善，而所有水平的用户在使用假肢进行活动以及执行自选任务时的感知难度方面均有所改善。
