Since the conventional methods of physical therapy may decrease the motivation of a patient for rehabilitation due to repetitive, monotonous movement, a new physical therapy system inducing a motivation from the patient is needed. The present study is intended to develop a physical therapy serious game for enhancement of dynamic balance control. The balance control therapy game was developed by the following steps: (1) survey of existing balance control therapy systems, (2) analysis of balance control literature, (3) ideation and architecture planning of the balance control therapy game, and (4) implementation of the balance control therapy game. The proposed physical therapy serious game can provide better usability, satisfaction, clinical effectiveness for balance control than the conventional methods.

Kegel exercise is commonly prescribed to improve the urination and evacuation capabilities of a patient. Assistive devices developed for Kegel exercise are found limited in terms of clinical effectiveness and motivation. The present study is intended to develop a serious game to support active and sustainable Kegel exercise for patients. A four-step process (benchmarking, analysis of patent and technology, ideation of hardware and software, and implementation) is applied in the present study to development of a Kegel serious game. The proposed serious game for active Kegel exercise needs to be validated in urology clinics.

Although motivation and fun are important for effective speech therapy, the conventional speech therapy is often conducted by using a textbook which can be boring to the speech-handicapped. The present study is to develop a speech therapy serious game for rehabilitation of the handicapped with articulation and fluency in speech. A speech therapy game was developed in the present study through the following four-step approach: (1) benchmarking analysis of 8 speech therapy systems, (2) analysis of 22 parents, (3) development of the framework of the speech therapy game and ideas for speech therapy game contents, and (4) implementation of the speech therapy serious game system using C# and the game engine Unity. The speech therapy serous game developed in the study can be of help for rehabilitation of articulation and fluency for the speech-handicapped.
