Duration of Playing Mobile Legends Online Games and Its Association with the Incidence of De Quervain Syndrome Among Adolescents at SMAN 2 Denpasar

Introduction: Playing Mobile Legends involves repetitive finger activities that increase the risk of injuries, such as De Quervain Syndrome (DQS). This study examines the association between the duration of gaming and the incidence of DQS among adolescents. Methods: A cross-sectional design was employed with 66 male students from SMAN 2 Denpasar selected through purposive sampling. Data on gaming duration were collected using questionnaires and smartphone logs. DQS was assessed using the Finkelstein test and a Visual Analog Scale (VAS). Spearman’s rho test was used for analysis. Results: A significant association was found between gaming duration and the incidence of DQS (p=0.009, r=0.319), indicating a moderate correlation. Most students playing for over 7 hours daily tested positive on the Finkelstein test. Conclusion: Prolonged gaming duration increases the risk of DQS. Education on time management and thumb stretching exercises can help prevent this injury. Keywords: de quervain syndrome, gaming duration, Mobile Legends, repetitive strain injury (RSI), adolescents
