The relationship between smartphone usage duration (using smartphone’s ability to monitor screen time) with hand-grip and pinch-grip strength among young people: an observational study

Abstract Background The use of smartphones has become widely popular, especially among young people, for multiple purposes other than communication, including gaming and internet browsing. hand wrist weakness is one the main complications associated with increased smartphones. This occurs due to repetitive flexion extension wrist, thumb, fingers, leading a significant musculoskeletal pathology. Little known about relationship between smartphone usage duration (using phones ability monitor screen time) hand-grip, pinch-grip strength. Therefore, study was aimed investigate association strength people. Methods One hundred males volunteered participate in study. Participants were briefly examined height weight using portable stadiometer digital scale. Hand-grip, measurement performed hand-held dynamometer. Smartphones obtained from daily average time reported last seven days. Results Mean participants 7.8 ± 2.2. There weak inverse hand-grip ( r= -.22, p = .03) r =-.28, .004). Linear regression revealed that 18.8 % variance 20.4 explained by age, duration, addition BMI only p’s < 0.00). Conclusions Prolonged related weaker pinch-grip. Despite relationship, showed might contribute as factor along age muscles’
