Background and Objectives: Given the increasing prevalence of smart phone usage, it can be considered as an important and significant issue in all aspects of human life. Therefore, the purpose of this study was to study the effect of duration of smartphone use on head and shoulders’ posture of young adults aged 20-35 years.
Methods: The statistical population of this study was young people aged 20 to 35 with smart phones who were resident of Kish Island in 2018. A sample of 50 people (25 men and 25 women) were selected voluntarily and purposefully. Low- user and High- user groups were identified by completing the form of addiction to smart cell phone, in assessing the status of upper limb, the shoulder position was measured by Scapular index and head position was measured by photogrammetric method technique and Kinovea software. Independent t-test was used for comparison of experimental variables between two groups. Data were analyzed with SPSS  22. P<0.05 was considered significant.
Results: The findings showed that there is a significant difference between upper limb posture in Low- user and High- user groups (P=0.033). There was also a significant difference in shoulder position between men and women (P=0.002). But regarding head positioning, there was no significant difference between men and women (P=0.436).
Conclusion: Thus, it seems that considering the significant difference between the two groups mentioned for upper limb posture, we can use the results of this study to inform, prevent and improve the upper.
