Along with development of medical science, stroke is showing an increasing trend of occurrence due to improvement in living standards and increase in aged population. In particular, about 56% of all stroke patients are suffering from hemiplegia, which bring difficulty in everyday activities. There are various means of rehabilitation for such hemiplegic stroke patients, but such methods cannot be carried out alone but must be accompanied by therapists. Patients must visit treatment facilities to receive treatment. Accordingly, under the consideration that treatment and rehabilitation of stroke can be assisted using functional game as an auxiliary means to continued counseling and treatment by physician without limitation on location, time, and cost, the purpose of this study is to propose a rehabilitation rhythm game based on motions using appropriate platforms such as PC and smart phones.
