Gesture Therapy (GT) is a virtual rehabilitation tool for the upper arm that has been in the making since 2008, and by now has successfully demonstrated therapeutic validity in two small clinical trials for stroke survivors. During this time, our group has published a number of contributions regarding different aspects of this platform ranging from hardware controllers to artificial intelligence algorithms guiding different aspects of the serious games behaviour, and clinical trial data from observable improvements in dexterity to changes in functional neuroreorganization. As we continue our research efforts in virtual rehabilitation and realising this knowledge in the GT platform, this paper presents an overview of the latest developments as well as a roadmap for future research.
