It’s all in real time, with the model adjusting the amount of stimulation required as the patient starts to recover. “We’re in the early stages of research and we’re having to Thought control Gold Coast University Hospital junior doctor and Griffith University medical graduate Dinesh Palipana is taking part in research which uses a ‘thought control’ approach to spinal cord injury rehabilitation. T however we know we have shown our real-time personalised model works, basically like a digital twin of the patient.” Dr Palipana is excited to be part of the research in his own backyard. “We’ve had equipment for many years where people passively he novel research involves car accident part-way through his exercise using stationary bikes, and Dr Palipana thinking about medical degree. stationary methods where people pushing the pedals of a Griffith University Professor David get on and the equipment moves specially adapted recline bike, Lloyd, Dr Claudio Pizzolato and his their legs for them.
