Some information categorized under the moniker tele-occupational therapy. Perhaps it is a Canadian term as all the following links are from the Canadian Association of Occupational Therapists (CAOT).
The periodical "OT Now" has a regular section on tele-occupational therapy. New issues are not open to the public, but older articles can be viewed. Here's a 2008 article by Jonathan Halton "Virtual rehabilitation with video games: A new frontier for occupational therapy".
