What this Trial Is About
This research aims to explore how smartphone addiction affects pinch strength, muscle stiffness, and hand and wrist function in young adults aged 18 to 25. The study is based on concerns that repetitive thumb and hand movements from smartphone use may cause issues like tendinosis, myofascial pain, and decreased muscle performance. It focuses on the link between muscle stiffness changes and pinch strength related to smartphone use, a topic considered important for understanding musculoskeletal health. Volunteers were divided into two groups based on their scores from the Smartphone Addiction Scale-Short Version (SAS-SV): those with smartphone addiction and those without. The study involved no treatment or intervention; participants were simply assessed once. Assessments included a questionnaire about wrist and hand function, a Finkelstein test, muscle stiffness measurements, and pinch strength tests, all conducted on the dominant hand by expert physiotherapists. Participants took part in a single 30-minute session where all tests and questionnaires were completed. The research team measured muscle stiffness and pinch strength at baseline and evaluated smartphone addiction levels and wrist/hand function. No follow-up or ongoing treatment was provided. This observational study helps to understand the physical effects of smartphone addiction on hand and wrist health in young adults.
