ARM / Arm Prosthesis Race



About the Team

OPRA is starting this year with two teams: e- and x-OPRA. In 2016 one team of Chalmers University in Goteborg participated and took 3rd place. "Since 2016, we have been adjusting the algorithms to improve control and movement accuracy. We have also integrated sensory feedback," explains team manager Max Ortiz Catalan.

OPRA Osseointegration is a multidisciplinary team from Chalmers University of Technology, in collaboration with Sahlgrenska University Hospital (Region Västra Götaland) and Integrum AB. Osseointegration as a medical technique has been developed in the 1960ies and initially made a name for itself with dental implants. Later, the research shifted towards prostheses and their attachment to the bone. Today, the OPRA team relies on their intelligent technology, which makes sensory feedback possible in everyday life thanks to implanted eletrodes. "Prostheses often have difficulties in their implementation in clinical use, mostly due to reliability problems. Osseointegration solves this problem and enables us to use implantable neuromuscular interfaces in everyday life. We want to help patients regain the functionality lost through amputation and thus improve their quality of life," says Max. With his team and the two pilots he wants to show what their osseointegrated prostheses are capable of.

Pilot - Tonney Forsberg

After an accident, Tonney Forsberg had to have his left forearm amputated. This does not prevent the Swede from renovating his house, repairing cars and building all kinds of things. His osseointegrated prosthesis makes this possible. "The change was immense. To experience what I can do with this prosthesis was a big step for me. It’s really good, but I would like to see more reliability in hardware design," Tonney says. "Four years ago, I watched the CYBATHLON on TV. It looked great, but I never thought I would participate myself.” Now Tonney starts for x-OPRA. He will not only surprise himself with his skills, but also impress the audience.
