This paper aims to develop an appropriate game interface design for frozen shoulder rehabilitation. The main treatment of frozen shoulder involves diagnose of doctor and proper rehabilitative exercise to break up adhesion and improve the joint mobility and functions. It leads to a problem that whether to do the exercise after the treatments of doctor is all depends on the patient’s motivation and often not execute. To address this, we construct an app game design which can be easily used by mobile platforms in order to enhance the motivations of patients to keep doing regular rehabilitation at home and the results can be uploaded into server for screening by doctor. The prototyping of this game design are conducted and several users are invited into the evaluation process to revise the game design.
