Objective: To determine the association between smartphone usage time and cervical ranges of motion (cROM). Methods: An observational analytical cross-sectional study on university students of both genders, located at a university in Lima during the year 2017. We used a questionnaire to gather demographic data, cell phone possession, total time of smartphone usage and by smartphone activities (calls, sms message, chat applications, social network applications, internet browsing and games), presence of neck dysfunction, and the use of a collar. Cervical ROM (flexion, extension, lateralization and rotation of both sides) was measured with a universal goniometer after the questionnaire. Results: 233 students (72.1% females) were analyzed with an average smartphone use of 332 minutes per day. The average range of motion was 48,6°±11,0 for flexion; 45,3°±11,5 for extension; 67,6°±11,1 for right rotation; 68,6°±9,5 for left rotation; 29,1°±8,3 for right lateralization and 26,5°±8,4 for left lateralization. Regression analysis shows negative association with cervical flexion and chat applications (β=-0.010 p=0.035), right lateralization with chat applications (β=-0.008, p=0.020) and right rotation with games (β=-0.041, p=0.026). No correlation was found between total usage of smartphone and cervical range of motion. Conclusions: There was no correlation between smartphone usage time and cervical ranges of motion (cROM). Activities like chat applications had a negative influence in flexion (p=0,035) and left lateralization (p=0,020); while games had the same effect in right rotation (p=0,026).
