The main challenge in the psychomotor and physical rehabilitation process is the low adherence of patients, motivated by the monotony of traditional exercises which generally generate dissatisfaction, fatigue, and a lack of perceived results. Gametherapy, driven by technological advancements, emerges as a promising alternative to overcome this obstacle, as it uses electronic games to make sessions more fun, stimulating, and rewarding. In this sense, this work proposes a methodology for the pre-selection and technical validation of games on the Android platform. The test device is low-cost and consists of a Raspberry Pi 4 operating with the LineageOS 22.2 system (Android), coupled to a touchscreen television. Using these tools, 77 games were installed and evaluated directly from the Play Store, and 14 selection criteria were established based on clinical and technical instructions. As a result, 37 games were approved, demonstrating therapeutic potential for upper limb rehabilitation. Furthermore, this initial catalog of Serious Games will be submitted to clinical validation by physiotherapists, aiming for future implementation in rehabilitation clinics to stimulate fine and gross motor skills.
