Cutting nails is an essential activity of daily living. In this study, a foot-operated safety nail clipper for people with stroke hemiplegia was developed in four phases using three-dimensional (3D) printing technology.
A user was identified to develop a foot-operated, safe nail clipper for people with stroke hemiplegia (Phase 1). A single user repeatedly used the technology to determine necessary improvements (Phase 2). Then, the usability was evaluated by four people with disabilities (Phase 3) before the clipper was manufactured at multiple institutions to determine its reproducibility (Phase 4).
The foot-operated safe nail clipper was upgraded during each phase. The Version 2.0 comprises twenty 3D printing materials and five readily-available materials.
A foot-operated safety nail clipper was developed for people with stroke hemiplegia. The number of parts increased as the device was upgraded the use of 3D printing and available materials. Based on a small-scale usability test, the device was best suited for people with stroke hemiplegia. The assistive device was shared with the assistive technology open platform as an open source. The four-phased process can be used to develop appropriate assistive technology devices through the Makers Movement in the future.
剪指甲是日常生活中必不可少的活动。本研究采用三维（3D）打印技术，分四个阶段为脑卒中偏瘫患者开发了一种脚踏式安全指甲刀。
首先确定一位用户，开发适用于脑卒中偏瘫患者的脚踏式安全指甲刀（第 1 阶段）。然后，由一位用户反复使用该技术来确定必要的改进（第 2 阶段）。接着，由四位残疾人评估其可用性（第 3 阶段），然后在多个机构制造该指甲刀以确定其可重复性（第 4 阶段）。
脚踏式安全指甲刀在每个阶段都进行了升级。版本 2.0 由二十种 3D 打印材料和五种现成材料组成。
为脑卒中偏瘫患者开发了一种脚踏式安全指甲刀。随着设备的升级，零件数量增加，使用 3D 打印和现成材料。基于小规模的可用性测试，该设备最适合脑卒中偏瘫患者。该辅助设备已作为开源共享到辅助技术开放平台。未来，通过 Maker 运动，四阶段过程可用于开发合适的辅助技术设备。
