Sounds fascinating, thanks ever so much.
Love the aspect of being able to start training in sitting.
However, I seriously doubt that the use of any electronic or purchased devices actually increases participation in exercise - the novelty will wear off sooner or later - like for the kids who have been using Wii or PS4 in rehab.

The only problem that I see is that trials have shown (at least with neurological clients) that balance training needs to occur about 4 times a week at least and therefore it is only feasible for Outpatients to be done as a home programme. That means each Clinic needs a device to trial it and then clients have to purchase it. Potentially difficult as many clients - esp. those who are off work due to injury or medical illness, are seriously short of funds. I mean, look at the people to complain about the surcharge... Also, all areas of balance need to be addressed in order to transfer exercise skills into functional activities and I am wondering whether your device does this.
I would be quite keen to have a look at a Board. if you are unable or not permitted to publically state which clinics have the device, would you be able to send me a pm, please???
Cheers,
