Co-design and Pilot Study in VR-based Physical Activity and Cognitive Training

There were two parts in this study, one was co-design (participants co-designed the device) and the other was a pilot intervention. The two parts were iterative. In the interventional part, participants were asked to cycling the co-design rehabilitation bike and also did reminiscence or any cognitive therapy at the same time. The intervention session lasted at least 15 minutes, twice a week for 12 weeks.
