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 - Magnus Niska

Magnus Niska is a Swedish nature boy who loves skiing and snowmobiling as much as the peace and quiet of fishing. He lives in Haparanda with his partner and their three children. For seven years now, he has been mastering his everyday life with his osseointegrated prosthesis with sensory feedback. “After an accident, a tumor grew in my right arm so that my forearm had to be amputated,” he describes this life-defining change.

Competing at CYBATHLON 2016 motivated and inspired him, and he was not entirely satisfied with his third place. The task with the wire loop, which had to be guided along a curved bar, was particularly difficult for him. “My prosthesis has no wrist, so I can neither turn nor flex the hand,” he explains. “I wish my next prosthesis had a motorized elbow and wrist joint”. But even without one, he goes to the CYBATHLON 2020 full of self-confidence: “I think I have a good chance this year, I want to win.”
