Improving fine motor skills, designing a 3D FDM printed orthosis to assist in the rehabilitation of individuals with hand spasticity

[v 1.0]
The project is currently in the alpha phase. I'm sharing the model for the finger, thumb, and wrist stabilizer, which can be molded to fit the wrist shape by heating it with a hairdryer or heat gun. To adjust the file to your hand, it should be scaled in the appropriate proportions using a 3D slicer program. The straps file should generally not be scaled, as it is used to adjust the tension force of the rubber

[v 2.0]
soon
I am currently working on creating a parametric .step file to easily and conveniently adjust hand dimensions, and the program will accordingly adjust the dimensions of the orthosis, which we will be able to directly export to an .stl file.

The project for stroke survivors enables the rehabilitation of fine motor skills, allowing for the safe elimination of flexor tensions. The primary goal is to lower the cost of the orthosis. The product will be available under an open-source license for self-production using a home 3D printer or can be commissioned for professional 3D printing. Target price range: 5-25$
The orthosis consists of 8 components, elastic rubber, and Velcro. It allows for independent, easy application, adjustment of finger straightening force, and customization to fit individual hand sizes. The wrist stabilizing element is shaped to fit the hand by heating the print

The orthosis is a student project that I created in the ergonomic design studio at the Faculty of Industrial Design, Krakow Academy of Fine Arts. It was developed under the supervision of Professor Czesława Frejlich and mgr. Karol Cyrulik
