Brain injury such as traumatic brain injury (TBI) and stroke is the major cause of long-term disabilities in many countries. The increasing rate of brain damaged victims and the heterogeneity of impairments decrease rehabilitation effectiveness and competence resulting in higher cost of rehabilitation treatment. On the other hand, traditional rehabilitation exercises are boring, thus leading patients to neglect the prescribed exercises required for recovery. Therefore, we propose game-based approach to address these problems. This paper presents a rehabilitation gaming system (RGS) for cognitive rehabilitation. The RGS is developed based on a proposed conceptual framework which has also been presented in this paper.

Acquired brain injury is one cause of long-term disability. Serious games can assist in cognitive rehabilitation. However, therapists' perception and feedback will determine game adoption. The objective of this study is to investigate therapists' intention to use serious games for cognitive rehabilitation and identify underlying factors that may affect their acceptance. The respondents are 41 therapists who evaluated a ''Ship Game'' prototype. Data were collected using survey questionnaire and interview. A seven-point Likert scale was used for items in the questionnaire ranging from (1) ''strongly disagree'' to (7) ''strongly agree''. Results indicate that the game is easy to use (Mean = 5.83), useful (Mean = 5.62), and enjoyable (Mean = 5.90). However intention to use is slightly low (Mean = 4.60). Significant factors that can affect therapists' intention to use the game were gathered from interviews. Game-based intervention should reflect therapists' needs in order to achieve various rehabilitation goals, providing suitable and meaningful training. Hence, facilities to tailor the game to the patient's ability, needs and constraints are important factors that can increase therapists' intention to use and help to deliver game experience that can motivate patients to undergo the practices needed. Moreover, therapists' supervision, database functionality and quantitative measures regarding a patient's progress also represent crucial factors. ª 2015 The Authors.
