Günümüzde akıllı telefonlar iletişim aracı olarak değil internette gezinmek için de kullanılan ve hayatın vazgeçilmez bir parçası olarak görülen teknolojik bir cihaz olarak tanımlanabilir. Akıllı telefon kullanan bireylerin kas iskelet sitemi açısından nasıl etkilendiğine dair çalışmalara literatürde sıklıkla rastlanmaktadır. Ancak dokunmatik ekran boyutunun değerlendirildiği çalışmalar sınırlıdır. Bu araştırmanın amacı, sağlıklı bireylerde akıllı telefon kullanımının farklı kavrama tipleri (ikili kavrama, üçlü kavrama, lateral kavrama) üzerindeki etkilerinin ekran boyutu açısından incelenmesidir. Farklı boyutlardaki ekranların, kullanıcıların kavrama tipleri üzerinde etkilerini araştırarak ekran boyutu özelliğinin kavrama tipleri üzerinde ne gibi etkileri olabileceğini araştırmaktır. Çalışmaya, en az bir yıldır akıllı telefon kullanan 150 üniversite öğrencisi dahil edildi. Tüm katılımcıların el-el bileği kavrama kuvveti, lateral kavrama kuvveti, ikili kavrama kuvveti ve üçlü kavrama kuvveti ölçümleri yapıldı. Erkeklerin kavrama kuvvetleri ekran boyutundan etkilenmezken kadınlarda ekran boyutunun ikili kavrama ve üçlü kavrama üzerinde etkileri olduğu belirlendi (p<0.05). Akıllı telefon dokunmatik ekran boyutlarının kavrama tiplerini etkileyebileceği görüşündeyiz.

Investigating the Effects of Smartphone Screen Size on Different Grip Types in Healthy Individuals: Screen Size Analysis

Öz

ABSTRACT
Smartphones can be defined as a technological device that is used not only as a means of communication but also for surfing the Internet and is seen as an indispensable part of life. Studies on how individuals using smartphones are affected in terms of musculoskeletal system are frequently encountered in the literature. However, studies evaluating the touch screen size are limited. The aim of this study is to examine the effects of smartphone use on different grip types (dual grip, triple grip, lateral grip) in healthy individuals in terms of screen size. The aim of this study is to investigate the effects of different sizes of screens on the grip types of the users and what effects the screen size feature can have on grip types. The study included 150 university students who had been using a smartphone for at least a year. Wrist grip strength, lateral grip strength, double grip strength and triple grip strength were measured for all participants. While men's grip strength was not affected by screen size, it was determined that screen size had effects on double grip and triple grip in women. (p<0.05). We are of the opinion that smartphone touchscreen sizes may affect grip types.
