These games have a purpose beyond pure entertainment, enabling sensorymotor training with content and targeted goals. Despite the promising use of serious games as a treatment strategy, the analysis of its utility, efficacy and validation in the VR domain for geriatric rehabilitation is scarce. Objective: To validate the content of the VirtuAlter serious game for postural balance rehabilitation of the elderly through virtual reality. Methodology: This is a descriptive study contemplating two stages: 1) Identification of the upper limb lateral reach reference values in 20 elderly without postural balance impairment with the instruments: Sociodemographic assessment, Berg Balance Scale, Short Physical Performance Battery, Lateral Reach Test (TAL); Lateral range analysis using the Microsoft® Kinect motion capture system (AL Kinect); 2) Content validation of the VirtuAlter serious game by analysis of 11 expert judges (physiotherapists and science and technology professionals or correlated areas) who played and expressed their opinions through the instruments: Content validation dimensions of the VirtuAlter serious game and System Usability Scale (SUS). The Shapiro-Wilk test, the Bland-altman analysis, the Content Validity Index (CVI) calculation and the Cronbach's Alpha coefficient were performed. Results: In stage 1, TAL and AL Kinect values of 23.2 ± 4.77; 21.1 ± 5.47 were observed on the right side and 22.9 ± 4.86; 22.7 ± 6.42 on the left side. The Bland-Altman dispersion model showed a bias of 0.19 for the left side and 2.02 for the right side. In stage 2, the total CVI of the game was 0.8 and the Cronbach alpha coefficient was 0.924. The judges identified the game with a satisfaction score of 67.73 on the SUS scale. The technical element items, clarity of the game narrative, image quality and speed of motion capture need adjustments before clinical execution. Conclusion: The lateral reach values will be adopted as parameters of the game for rehabilitation application in elderly with balance impairment. The content of the VirtuAlter serious game is valid and corresponds to an adequate technological tool for training the postural balance of the elderly, presenting good usability.Acesso AbertoRealidade virtualReabilitaçãoEquilíbrio posturalIdososmasterThesisCNPQ::CIENCIAS DA SAUDE::FISIOTERAPIA E TERAPIA OCUPACIONAL
