Abstract
Smartphone usage has become ubiquitous, with over half the global population owning these devices. However, excessive smartphone use has been linked to various hand-related disorders. This short communication explores the impact of prolonged phone use on hand function and its association with musculoskeletal disorders like carpal tunnel syndrome (CTS) and De Quervain's tenosynovitis (DQT). CTS, resulting from median nerve compression, is prevalent among smartphone users who engage in repetitive wrist and finger movements. Likewise, DQT, caused by inflammation of thumb tendons, is increasingly observed in individuals who frequently use their thumbs for texting and gaming. Studies indicate that prolonged daily smartphone usage correlates with diminished grip strength, increased wrist pain, and a heightened risk of developing CTS and DQT. Young adults, particularly university students, are disproportionately affected, with over 50% of heavy smartphone users reporting hand pain or dysfunction. This communication highlights the need for ergonomic interventions, awareness of proper smartphone use, and targeted prevention strategies to mitigate these risks. Addressing factors like poor posture, prolonged device use, and thumb-dominated activities can help prevent long-term hand disorders. By recognizing these health risks and taking proactive measures, individuals can reduce the incidence of hand dysfunction related to excessive phone use and improve their overall hand health.
