Seeing their progress through their PGHD could potentially encourage them to keep going and do more of their rehabilitation exercises. If their PGHD shows that the system is helping their recovery, they would use it more and more. PGHD may help them know their movement mistakes, and correct themselves. It may be important for the PGHD to be positive, as low PGHD would indicate that the system was not helping with their rehabilitation. Low PGHD could cause survivors to be less inclined to continue using the system. If they felt they did not perform an exercise as well as their resulting PGHD showed, they would lose confidence on the system. A few survivors felt that PGHD would have no effect at all on their health behaviour.
| Clinicians mainly anticipated that PGHD would be potentially encouraging for stroke survivors, but for slightly different reasons. PGHD would inform survivors of how much they have exercised and increase their understanding on why they have to do the exercises. Increased understanding could encourage them to be more complaint. They agree that negative PGHD could be discouraging.
