This paper proposes a software toolkit that Physiotherapists can use to integrate physical therapy exercises with a variety of video games. The toolkit will support a variety of motion tracking technologies and the data from these sensors will help the therapist monitor the performance of the patients and control parameters to advance the therapy appropriately. This technique will be especially useful for disabled patients in developing nations with little access to quality rehabilitation facilities but where computers and mobile phones have penetrated extensively. Using popular games for therapy helps the patient become motivated enough to perform therapy exercise steps repeatedly.
