Brief summary: Mobile phones have different uses in different disciplines, and this encourages long-term use. For optimum comfort use, it is important to ensure users' awareness when purchasing mobile phones that match their hand sizes. The number of studies in the literature on this subject is limited. In this context, the aim of our study is to investigate the relationship between smartphone and hand anthropometry measurements and upper extremity pain and functions.

Detailed description: Phone design features cause different problems on body mechanics and musculoskeletal system. With the use of smartphones, people tend to maintain incorrect postures for long periods of time, which increases tension in the body. This situation causes complaints such as cervical disc herniation, tingling complaints in different body parts, overuse injuries, Upper Crosses syndrome, and carpal tunnel syndrome. On the other hand, the use of smartphones is increasing among students for reasons such as providing students with freedom of time and space, increasing the speed of teaching and learning, supporting one-on-one learning, and increasing the number of ideas produced by encouraging a group discussion environment.

Mobile phones have different uses in different disciplines, and this encourages long-term use. Although many musculoskeletal system structures can be affected by incorrect postures due to the long-term use of smart mobile phones, it is thought that the upper extremity is most affected. Therefore, the aim of our study is to investigate the relationship between smartphone dimensions and hand anthropometric measurements and upper extremity pain and functions in order to raise awareness when purchasing mobile phones that match users' hand sizes for optimum comfort and use.
