Ten years ago, Gert-Jan Oskam was rendered paralysed after a traumatic cycling accident. Now, a team of Swiss scientists have made it possible for him to walk again, thanks to an innovative brain-spine interface (BSI). This ‘digital bridge’ provides an electric connection between his brain and his spinal cord to reestablish communication and control motor functions.
The process involves the implantation of two electronic devices into Oskam’s brain. These devices detect his brain activity when he wants to move his legs and relay the signals to a processing unit he wears on his back. An algorithm is then used to decode the signals, which are then sent as instructions to the second electronic device inserted into his spine. This device stimulates the nerves to control the movements of his legs.
Gert-Jan Oskam underwent two surgeries and around forty rehabilitation sessions to regain voluntary movement of his legs. He was able to walk again and could even move his hips without the device after just a few minutes. Amazingly, he can now even take a few steps using crutches without the need for assistance.
The Swiss Federal Institute of Technology Lausanne (EPFL), along with partner companies ONWARD medical and CEA, have received funding from the European Innovation Council (EIC) to develop a commercial version of the digital bridge and make the technology accessible globally. They are also planning clinical trials with three other participants to assess its effects on restoring arm movement. The researchers will also examine if the device shows promising results in restoring mobility to people who suffer paralysis due to stroke.
The invention of the ‘digital bridge’ is an incredible breakthrough. It has given Gert-Jan Oskam hope that he will one day regain his full mobility. This could set an example and pave the way to restoring mobility and quality of life for many other paralysed individuals.
The Swiss Federal Institute of Technology Lausanne (EPFL) is an institute of technology based in Switzerland. It has been dedicated to research and education in science and engineering since 1853. EPFL has achieved a unique position among universities worldwide, by managing to combine world-class research with strong societal and economic impact. With this ‘digital bridge’, EPFL has demonstrated its commitment to finding innovative solutions for a variety of medical and technological issues.
Gert-Jan Oskam is a man who has defied all the odds. As a result of the cycling accident, he was paralysed from the chest down 10 years ago. Against all expectations, he has made immense progress and has demonstrated the resilience of the human spirit. His story of recovery and perseverance is an inspiration to many, and goes to show the incredible potential of technology in aiding people with physical and mental disabilities.
