This study focuses on creating a better wrist-driven orthosis (WDO) for people with spinal cord injuries using 3D printing. Traditional WDOs can be heavy, uncomfortable, and hard to get, so the researchers aimed to make them more accessible and customizable. The new 3D-printed WDO is cheaper to make (around $15) and takes less time to assemble (about 1.5 hours). It also allows for easier customization to fit individual users. The design of the 3D-printed WDO is available for free online, so anyone can use it and improve upon it. User testing showed varying improvements in hand function, with some participants experiencing increased grasp strength and improved ability to perform tasks.
The open-source design and reduced fabrication costs of the 3D-printed WDO can make assistive devices more accessible to individuals with SCI, particularly in low-resource settings.
3D-printing allows for greater customization of WDOs to fit individual user needs, potentially improving comfort, function, and device acceptance.
The open-source nature of the project can foster collaborative innovation and accelerate the development of new and improved hand orthoses.
