Brief Summary

Screen time is defined as the time spent on many electronic and technological devices such as laptops, tablets, televisions, game consoles, and smartphones. The largest portion of screen time is made up of smartphones, which are currently used at very high rates. The increase in screen time, which describes the time an individual spends in front of technological devices, can pave the way for various physical problems when not controlled. The most important of these problems caused by excessive screen use due to increased smartphone use is postural disorders. Based on this, the original value of this research is to examine and reveal the effects of smartphone use on balance and dual-task performance. Scientific data can be reached on the negative effects of increased screen use caused by smartphone use.

Detailed Description

Screen time is defined as the time spent on many electronic and technological devices such as laptops, tablets, televisions, game consoles, and smartphones. The largest portion of screen time is made up of smartphones, which are currently used at very high rates. The increase in screen time, which describes the time an individual spends in front of technological devices, can pave the way for various physical problems when not controlled. The most important of these problems caused by excessive screen use due to the increase in smartphone usage times is postural disorders. It was planned to examine and reveal the effects of smartphone usage time on balance and dual-task performance. This study was planned as a prospective cross-sectional study. It was planned to evaluate at least 50 participants. The average smartphone usage times of the participants will be recorded. Static and dynamic balance tests (Y Balance Test and Flamingo Test) will be applied and a cognitive task will be added to these tests by including smartphone usage, thus evaluating dual-task performance. The obtained data will be analyzed.
