■探讨定制的3D打印辅助技术(AT)对神经功能缺损患者的功能表现和可行性的影响。
■将患有神经功能缺损的患者招募并随机分为定制的3D打印辅助设备组(第1组;n=17)或标准设备组(第2组;n=14)。该设备旨在帮助他们写作,勺子使用,和打字。每位患者都接受了为期4周的设备干预(每次30分钟,一周两次)。
■我们观察到肩部外展的显着差异(p=.00),外部旋转(p=.01),和内部旋转(p=.02)在第1组中。两组间外展(p=.05)和外旋(p=.05)差异有统计学意义。第1组在没有AT(p=.04)和AT(p=.02)的情况下在写作方面取得了显着改善,没有AT(p=.02)和AT(p=.03)的勺子使用,和偏瘫侧分型与AT(p=.00)。第2组在没有AT的情况下实现了书面的显着改善(p=0.01),偏瘫侧分型无AT(p=0.01),和bil侧打字用AT(P=0.05)。此外,其他结局指标无显著差异.
■这项研究表明,定制的3D打印AT可以改善神经功能缺损患者的肩部主动运动。AT干预后对功能性手任务有积极影响。提供定制的AT和特定的培训可以提高干预措施的有效性。使用3D打印技术生产定制AT的可行性,具有成本效益和效率的潜力。
与传统辅助装置相比,结合夹板的3D打印辅助装置可以改善神经功能缺损患者的肩部主动运动。辅助设备干预后对功能性手任务的积极影响。
UNASSIGNED: To explore the effects of customized 3D-printed assistive technology (AT) on functional performance and feasibility in patients with neurological impairment.
UNASSIGNED: Patients with neurological impairment were recruited and randomized into customized 3D-printed assistive device group (group 1; n = 17) or standard device group (group 2; n = 14). The device was designed to assist their writing, spoon using, and typing. Each patient underwent 4-week intervention with the device (30 min per session, twice a week).
UNASSIGNED: We observed significant differences in shoulder abduction (p = .00), external rotation (p = .01), and internal rotation (p = .02) in group 1. And significant differences in abduction (p = .05) and external rotation (p = .05) between the 2 groups. Group 1 achieved significant improvements in writing without AT (p = .04) and with AT (p = .02), spoon use without AT (p = .02) and with AT (p = .03), and hemiplegia-side typing with AT (p = .00). Group 2 achieved significant improvements in writing without AT (p = .01), hemiplegia-side typing without AT (p = .01), and bil-side typing with AT (P = .05). Moreover, no significant differences were noted in other outcome measures.
UNASSIGNED: This study demonstrated that customized 3D-printed AT can improve shoulder active motion for patients with neurological impairment. A positive effect in functional hand tasks after AT intervention. Offering customized AT with specific training could enhance the efficacy of interventions. The feasibility of using 3D printing technology to produce customized AT, which has the potential to be cost-effective and efficient.
3D-printed assistive device incorporating a splint can improve shoulder active motion compared to conventional assistive device for patients with neurological impairment.A positive effect in functional hand tasks after assistive device intervention.
