Abstract
Aim: To design and manufacture a patient-specific assistive device optimized for patient function after estimating the disability status of a patient with brain injury through 3D printing technique Materials and methods: The left hand of a man with right-side hemiparesis was scanned with a three-dimensional scanner, and the left-hand image was flipped over to the right side to design the orthosis. To change devices easily, a connector was designed to connect the devices and was easily detachable with the orthosis by using the magnetics. To enable the writing, a round-shaped ring was attached to the orthosis to fix a pen. The Jebsen-Taylor Hand Function Test (JHFT) and Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST) were evaluated one month after the application. Results: The JHFT score improved after application 3D printed devices. In most QUEST items, 3D printed devices showed better results than ready-made assistive devices. The typing speed became faster in 3D printed devices than in ready-made assistive devices. The patient was satisfied with the orthosis in writing a pen, eating food and typing keyboard because of its fitness to his hand and easy-to-use. Conclusion: We designed and manufactured a patient-specific assistive device optimized for patient function after estimating the disability status of a patient with brain injury through 3D printing techniques. We hope to provide low-cost, customized devices to disabled patients through 3D printing techniques. Implications for Rehabilitation We designed and manufactured a patient-specific assistive device optimized for patient function through 3D printing technique. We hope to provide low-cost, customized devices to disabled patients through 3D printing techniques.
