为了： 1) 描述对 DEKA 手臂的满意度和可用性的看法以及对 DEKA 手臂或个人假肢的偏好； 2) 通过 DEKA Arm 配置级别比较满意度和可用性的感受； 3) 评估研究完成者和未完成者的满意度和可用性；以及那些想要和不想接受 DEKA 手臂的人。该研究分为两个阶段：实验室（A 部分）和家庭试验（B 部分）。 32 名截肢参与者（50% 经桡动脉、38% 经肱动脉和 13% 肩部）完成了 A 部分，18 名完成了 B 部分，其中 16 名（89%）在基线时是假肢使用者。对满意度、可用性和用户偏好进行了测量。比较了仅 A 部分的完成者和 A 部分和 B 部分的完成者的回答。评估了 DEKA 手臂相对于个人假肢的偏好以及想要接受 DEKA 手臂的参与者的比例。研究了满意度、可用性和获得 DEKA 手臂的愿望之间的关系。在 A 部分结束时，完成实验室培训的 32 名参与者中有 22 名 (69%) 想要获得 DEKA 手臂，5 名 (16%) 可能想要一个。在 B 部分结束时，完成家庭试用的 16 名假肢使用者中，有 14 名（88%）人更喜欢 DEKA 手臂的整体功能，13 名（81%）人更喜欢 DEKA 手部功能，14 名（88%）人更喜欢 DEKA 手腕功能。相比之下，14 人 (88%) 更喜欢自己假肢的重量，13 人 (81%) 更喜欢自己假肢的外观。 DEKA Arm 的大多数方面都被评为“易于使用”。没有项目被评为“困难”。除了重量、肩部外观和安全带外，用户对 DEKA Arm 的大部分方面都感到满意。配置级别的感知可用性或满意度几乎没有差异。有关获得 DEKA 手臂的愿望的调查结果仅适用于完成研究的人。未完成者对 DEKA Arm 的看法不如完成者。满意度与参与者表达的未来获得 DEKA 手臂的愿望密切相关。为了最大限度地提高采用 DEKA Arm 的可能性，研究结果表明，在最终确定处方建议之前，实验室和家庭使用试验可能都是有用的。
To: 1) describe perceptions of satisfaction with and usability of the DEKA Arm and preferences for the DEKA Arm or personal prosthesis; 2) compare perceptions of satisfaction and usability by DEKA Arm configuration level; and 3) evaluate satisfaction and usability for study completers and non-completers; and for those who did and did not want to receive a DEKA Arm. The study had 2 phases: in-laboratory (Part A) and home trial (Part B). 32 participants with amputation, (50% transradial, 38% transhumeral and 13% shoulder) completed Part A and 18 completed Part B 16 (89%) of whom were prosthesis users at baseline. Measures of satisfaction, usability and user preferences were administered. Responses were compared for completers of Part A only and completers of Parts A and B. Preferences for the DEKA Arm over personal prosthesis and proportion of participants who wanted to receive a DEKA Arm were evaluated. Relationships between satisfaction, usability and desire to receive a DEKA Arm were examined. At end of Part A, 22 (69%) of the 32 participants who completed in-laboratory training wanted to receive a DEKA Arm and 5 (16%) might want one. At end of Part B, 14 (88%) of 16 prosthesis users who completed the home trial preferred the overall function of the DEKA Arm, 13 (81%) preferred DEKA hand function and 14 (88%) preferred DEKA wrist function to their own prosthesis. In contrast, 14 (88%) preferred the weight and 13 (81%) preferred the look of their own prosthesis. Most aspects of the DEKA Arm were rated “easy” to use. No items were rated as “difficult”. Users were satisfied with most aspects of the DEKA Arm, except for the weight, shoulder appearance and harnessing. There were few differences in perceived usability or satisfaction by configuration level. Findings about desire to receive a DEKA Arm pertain only to study completers. Non-completers viewed the DEKA Arm less favorably than completers. Satisfaction was strongly related to participants’ expressed desire to receive a DEKA Arm in the future. To maximize likelihood of adoption of the DEKA Arm, findings suggest that both an in-laboratory and a home use trial may be useful prior to finalizing a recommendation for prescription.
