the game and summarised data showing progress was favoured. Parents were incentivised by this opportunity for their child to receive help and take responsibility for therapy. Appearance/comfort: The devices were programmed to display the time, in response to requests from YP. Wearing two devices was mildly perturbing for older participants as this would be considered unusual, though all were prepared to do it for the project duration. Access to participants: Recruitment to the workshops through advertising and patient groups was challenging; however, in the planned study, we will recruit through the NHS. Conclusion The participatory design process informed plans for the proof of concept stage of the study, hopefully leading to a product and approach that will be fun, easy to integrate into everyday life, and have the capacity to increase use of the affected arm and hand.
