Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

There is no study that examines the effect of problematic use of smartphones, which has become a global problem today, on reaction time and cognitive functions together. This study was planned to examine the effect of problematic smartphone use on upper extremity functions and cognitive functions. Participants' problematic smartphone use will be evaluated with the Smartphone Addiction Scale Short Form. Within the scope of upper extremity functions, Quick Disabilities of Arm, Shoulder \& Hand Questionnaire, reaction time and grip strength will be evaluated. Reaction time will be measured with BlazePod Trainer (Blazepod Trainer Device, Play Coyotta Ltd, Tel Aviv, Israel). Jamar dynamometer (Performance Health, Warrenville, IL) will be used to evaluate grip strength. Cognitive functions will be assessed using the Stroop Test ÇAPA Form, Trail Making Test and Cognitive Failures Questionnaire.
