      has led to the increased availability of smartphones in daily life. Smartphones have become a&#xD;
      part of everyday life, but with some problems. Smartphone addiction has been an important&#xD;
      topic of research and discussion as a type of addiction that develops depending on the&#xD;
      frequency of smartphone use. Researches have pointed out that smartphone addiction can cause&#xD;
      both physical and mental problems. As a result of a study conducted in the literature,&#xD;
      continuous use of smartphones has been found to cause sleep disturbances, stress, anxiety,&#xD;
      decrease in physical activities and many diseases. In this study, the relationship between&#xD;
      the concept of smartphone addiction and musculoskeletal problems and cognitive flexibility in&#xD;
      young people will be investigated.&#xD;
