## 2 Materials and Methods  
### Approach  
ERC has actively engaged in various international multidisciplinary projects aimed at the continual advancement of SG [13]. This collaborative effort has culminated in developing Stasism, a comprehensive cost-effective social online SG platform designed to benefit individuals with cerebral palsy and other movement disorders in different settings [14]. The Stasism platform strongly emphasizes inclusivity and accessibility, requiring only readily available and affordable commercial hardware for use. All games are developed in three dimensions (3D) using Unity, and MediaPipe framework is used to identify the body movements. They provide both visual and auditory feedback to the player. Briefly, this system has been developed to support personalized telerehabilitation and telemonitoring for individuals requiring rehabilitation or continuous monitoring. The platform collects and assesses relevant physiological, kinematic, and environmental information by integrating diverse sensors and validated data analytic approaches. The platform's built-in diagnostic tools allow therapists to monitor patients' performance remotely. These tools include a static balance test using a balance board and performance analytics (e.g., percentage of completed tasks, speed, and precision). Daily assessments of patient progress are available to therapists and take 2-10 min to review. It enables tailored rehabilitation activities according to individual requirements, permits remote monitoring of patient advancement (e.g., balance assessment), and delivers immediate feedback. In order to ensure the confidentiality of patient information and protect their privacy, the platform ensures the secure transmission and storage of data. Descriptions and objectives of the SG used in this study are presented in Table 1; screenshots of the SG are presented in Figure 1.
