I recently posted here that I found a product from a company called Playwork.
To me this is a startup that is going to change the rehabilitation world and I highly recommend checking it out.
Beyond the fact that you can play games during the rehabilitation process - the most important thing that they have a track of each user’s data so you can know how everyone is progressing and what needs to change.
Recommend watching the videos page - https://www.playwork.me/exercise-clips
Good luck to everyone who is in the process of rehabilitation
