A body-powered functional and cosmetically appeasing hand with moving interphalangeal joints (IPJ-Hand) was created. Function and satisfaction with the IPJ-Hand, conventional hand (CH) and functional hook (FH) in trans-radial prosthesis users were evaluated.
Eight participants with trans-radial amputations were provided with three prosthetic hands and performed the Nine Hole Peg Test (NHPT), Brief Activity Measure of Upper Limb Amputees (BAM-ULA) and Quebec User Evaluation of Satisfaction with Assistive Technology QUEST).
The data are shown as the median and interquartile range (IQR) due to skewed data distribution. Differences across hands were seen in NHPT with CH 57 (13.3), FH 49.5 (26.5), IPJ-H and 49 (14.8) seconds respectively. BAM-ULA, 10 (1.5), FH 10 (0.7), and IPJ-Hand 10 (1.7). QUEST scores, FH 28.5 (7.2) with the highest score, IPJ-Hand 26 (6.8), and lastly CH 25.5 (9.2).
Individual participant results varied, with some participants performing better on the NHPT when using the IPJ-Hand when compared to the CH and FH. No differences between hands on the BAM-ULA were seen, and although no large differences in QUEST were observed, users performed best using IPJ-Hand.Key messagesAn interphalangeal joint prosthetic hand (IPJ-Hand) offers the similar function of a prosthetic hook, and the appearance of a conventional hand, but with improved dexterity.Minimal resources are needed to create the IPJ-Hand for prosthesis wearers.
设计了一种带指间关节活动的可提供功能且美容外观的肌电手（IPJ-Hand）。评估了 IPJ-Hand、常规手（CH）和功能性钩（FH）在桡骨截肢患者使用中的功能和满意度。
8 名桡骨截肢患者配备了三种假肢手，进行了九孔钉测试（NHPT）、上肢截肢者简要活动测量（BAM-ULA）和魁北克用户对辅助技术满意度的评估（QUEST）。
由于数据偏态分布，数据显示为中位数和四分位距（IQR）。在 NHPT 中，CH 为 57（13.3），FH 为 49.5（26.5），IPJ-H 为 49（14.8）秒，差异显著。BAM-ULA 为 10（1.5），FH 为 10（0.7），IPJ-Hand 为 10（1.7）。QUEST 评分，FH 得分最高为 28.5（7.2），IPJ-Hand 为 26（6.8），而 CH 最低为 25.5（9.2）。
个体参与者的结果各不相同，与 CH 和 FH 相比，一些参与者在使用 IPJ-Hand 进行 NHPT 时表现更好。在 BAM-ULA 上没有观察到手之间的差异，虽然 QUEST 观察到的差异不大，但用户使用 IPJ-Hand 表现最好。
指间关节假肢手（IPJ-Hand）提供了假肢钩的类似功能和常规手的外观，但具有更高的灵巧性。为假体佩戴者制作 IPJ-Hand 所需的资源最少。
