Effects of 3D Printing Writing Assisitive Device on Feasibility in Patients With Nerve Injury

Injury to the central or peripheral nerves can lead to limited hand function and further affect the ability of writing. The use of assistive devices can assist writing performance. However, the habit of holding the pen and the ability of the individual case will affect the selection of aids and the efficiency of writing. The 3D printing aids can be individually designed and adjusted to different angles and types. There is no criterion for 3D printing aids decision, often using a case-by-case trial subjective way to confirm, matching takes more time. Aim: To compare the applicability and efficiency of different types of 3D-printed writing aids in nerve injury cases, and to explore which factors affect the choice of aids.
