Effect of Smartphone Usage

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.

About this study

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.

Treatment and study plan

Primary outcomes

Smartphone usage time

Time frame: Baseline

The average daily smartphone usage time will be calculated by dividing the total smartphone usage time for the last week by 7. The average smartphone usage time will be recorded in minutes.
Y Balance Test

Time frame: Baseline

The Y balance test is a time-efficient test that evaluates the dynamic limits of stability and asymmetric balance in three directions (anterior, posteromedial, and posterolateral). The test setup consists of three tape measures with distances in cm on them, one located anteriorly, the other two posterolaterally and posteromedially.
Flamingo Balance Test

Time frame: Baseline

During the test, the participant will be asked to stand on the board with his/her foot, lift his/her other foot off the ground, and hold his/her knee with the same hand to maximum flexion. The stopwatch will be started and the measurement will begin when the participant releases the hand of the researcher from whom he/she receives support. The stopwatch will be stopped when the participant releases his/her foot or when any part of his/her body touches the ground.
