Students at Kennesaw State University have developed a finger support to correct finger deformities and restore motor control. Finger deformities are a common symptom among patients suffering from arthritis. Current corrective splints and braces are bulky, uncomfortable, and have limited ways to adjust. The new finger support would be more functional then current splints available on the market.

“Our support was designed to be used in ‘functional positions,’ meaning that you are able to slip it over your finger and perform normal tasks with your hands without difficulty,” said Simin Nasseri, professor of mechanical engineering at Kennesaw State University's Southern Polytechnic College of Engineering and Engineering Technoloy. “Our final design is very durable and allows for a wide range of finger positions in order to maximize function.”

 

 

From the Kennesaw State University article: "Armed with extensive experience in biomedical and manufacturing engineering, and with several family members and friends who have finger deformities, Nasseri said she was inspired to develop an improved finger support that would allow others to tackle daily tasks more freely. With the help of students, and after several months of research and mechanical testing, she has created a composite support with a soft polymer shell and a thin aluminum, steel or carbon fiber sheet running the length of the apparatus to provide rigidity. The shell was printed entirely in KSU’s 3D Center and the sheet was cut in the machine shop just across the hall in the University’s Engineering Technology Center.

Nasseri started by conceptualizing designs of her own and soon began to recruit some of her undergraduate students in order to introduce them to the intricacies of engineering research. Since spring 2017, five students have played roles in writing literature reviews, perfecting the design, running simulations, fabricating and conducting mechanical testing on the finger support. As a team, they have co-authored two journal papers and presented their findings at a regional conference. White, who is conducting a directed study with Nasseri this semester, will complete further testing and hopes to present her discoveries at the National Conference on Undergraduate Research to be held at KSU in April."
