People with central nervous shortages, such as MS can utilize appropriate training approaches that improve their ability to accomplish activities in daily life. The MS symptoms and disease progression in People with Multiple Sclerosis (PwMS) are different, and each has its development speed. It is essential to accommodate adaptive training with patient's characteristics, and rehabilitation needs to address this diversity. This paper proposes a new gait rehabilitation approach in PwMS training using adaptive, individualized exergames. The exergames have been designed and developed inspired by four regular physiotherapy exercises. The suggested games are displayed on the floor using a projection-mapping approach to provide a stable environment and ensure practical exercise training for PwMS. Furthermore, the proposed method is empowered using dynamic difficulty adjustment algorithms to control the adaptivity of the games. We conducted a user study to evaluate patients' reactions to the automated difficulty adjustment of game levels. Our findings showed that none of the PwMS followed the same training path as the others. It reveals that each patient recovers at a different rate, underlining the importance of adaptability in this type of treatment. Individualized adaptive training, which was provided to each MS patient based on their development, has been described as beneficial and appreciated.
