Objective: The aim of the study is to investigate the effect of neck extensor muscle endurance on neck pain, neck disability and sleep problems among university students with smartphone addiction. Material and Methods: A total of 192 university students aged 18-25 years participated in the study. ''Smartphone Addiction Scale-Short Form'' was used to determine smartphone addiction. Neck extensor muscle endurance was assessed using the ''Cervical Extension Endurance Test'', neck pain at rest and during activity was analyzed using the ''Visual Analog Scale'', neck disability was assessed using the ''Neck Pain and Disability Index'', and sleep problems were investigated with the ''Pittsburgh Sleep Quality Index''. Results: It was found that 45.8% of the university students were addicted to smartphones. Neck extensor muscle endurance (p=0.029) was significantly lower, neck disability (p=0.039) and neck pain (rest pain p=0.050; activity pain p=0.012) were significantly higher in the smartphone addicted group. Neck extensor muscle endurance was not found to be associated with pain, neck disability and sleep quality among the participants with smartphone addiction. However, it was maintained that there is a positive correlation between neck disability, pain and sleep quality (p<0.005). Conclusion: Smartphone addiction causes neck pain, neck disability and sleep problems by weakening neck functions. Neck injury is linked to pain and sleep quality in smartphone addicts. Our results emphasize the importance of informing individuals about the risks of smartphone addiction. Especially in individuals with smartphone addiction, it is recommended to reduce the duration of phone use.

Amaç: Çalışmanın amacı akıllı telefon bağımlılığı olan üniversite öğrencilerinde boyun ekstansör kas enduransının boyun ağrısı, boyun yeti yitimi ve uyku sorunlarına etkisini incelemektir. Gereç ve Yöntemler: Çalışma kapsamında 18-25 yaş arası 192 üniversite öğrencisi değerlendirilmiştir. Çalışmada demografik bilgiler için sosyodemografik bilgi anketi ve akıllı telefon bağımlılığını tespit etmek için ''Akıllı Telefon Bağımlılık Ölçeği-Kısa Formu'' kullanılmıştır. Boyun ekstansör kas enduransı ''Servikal Ekstansiyon Endurans Testi'', istirahat ve aktivite sırasındaki boyun ağrısı ''Görsel Analog Skala'', boyun yeti yitimi ''Boyun Ağrı ve Dizabilite İndeksi'', uyku sorunları ''Pittsburgh Uyku Kalitesi İndeksi'' ile değerlendirilmiştir. Bulgular: Çalışmada değerlendirilen üniversite öğrencilerinin %45,8'inin akıllı telefon bağımlısı olduğu görülmüştür. Akıllı telefon bağımlısı olan grupta boyun ekstansör kas enduransı (p=0,029) istatistiksel olarak anlamlı düzeyde düşük, boyun yeti yitimi (p=0,039) ve boyun ağrısı (istirahat ağrısı p=0,050; aktivite ağrısı p=0,012) ise istatistiksel olarak anlamlı düzeyde yüksek bulunmuştur. Akıllı telefon bağımlılığı olan katılımcılarda boyun ekstansör kas enduransı ile ağrı, boyun yeti yitimi ve uyku kalitesi arasında ilişki bulunamamıştır. Ancak boyun yeti yitimi ile ağrı ve uyku kalitesi arasında pozitif korelasyon olduğu saptanmıştır (p<0,005). Sonuç: Akıllı telefon bağımlılığı boyun fonksiyonlarının zayıflamasına neden olarak boyun ekstansör kas enduransının azalmasına, boyun yeti yitimine, boyun ağrısına ve uyku sorunlarına neden olmaktadır. Akıllı telefon bağımlılarında boyun yeti yitiminin ağrı ve uyku kalitesi ile ilişkili olduğu görülmektedir. Sonuçlarımız, bireylerin akıllı telefon bağımlılığı ve riskleri hakkında bilgilendirilmesinin önemini vurgulamaktadır. Özellikle akıllı telefon bağımlılığı olan bireylerde telefon kullanım süresinin azaltılması önerilmektedir.
