Brief Summary

In the planned study, young adults between the ages of 18-35 with different phone usage durations will be evaluated. The aim of the study is to investigate whether the average daily phone usage time has a direct relationship with neck muscle endurance, rough grip strength, lateral grip strength and head posture, and whether there is an indirect relationship with postural control. People who have phones with IOS 12 or Android 9 and above will be invited to the study. By looking at the screen time tracking feature in these versions, the daily phone usage hour for the last week will be calculated and the participants will be divided into two groups as the daily phone usage average of 5, and below and 5 hours. In the planned study, neck endurance will be tested on flexor and extensor muscle groups in accordance with the literature. The lateral flexion and anterior tilt angles will be calculated with two photographs taken from the anterior and lateral sides of the head posture of the person's shoulder, and the hand grip strength will be measured with a Jamar hand dynamometer and the lateral grip strength will be measured with a pinchmeter. Postural control evaluation will be measured by means of center of pressure-CoP parameters measured with TekScan brand pressure platform. The study is planned to be carried out in the Movement Analysis Laboratory of the Faculty of Physical Therapy and Rehabilitation of Dokuz Eylul University. Participants will be selected from healthy adults between the ages of 18-35 who volunteered to participate in the study among the students of the Faculty of Physical Therapy and Rehabilitation, their relatives and the relatives of the researcher. The study is planned to be completed within 6 months following ethical approval.
