520 _aBackground: The use of smartphones and mobile devices has become widespread, particularly among youth, and the possible impacts on hand function and structures have not been clarified during bilateral and unilateral use of smartphone. Purpose: This study was conducted to investigate and compare between bilateral and unilateral use of smartphone on cross sectional area of median nerve in healthy university students. Subjects and methods: Fifty-six students aged 18-25 years old were recruited from Faculty of Physical Therapy Kafrelsheikh University. By using noninvasive ultrasonography, cross sectional area (CSA) of median nerve was measured while subjects typed specific text on smartphone using bilateral hands then unilateral hand. Results: The paired t test showed significant increase in CSA of median nerve in unilateral than bilateral hands use of smartphone(P<.001). Conclusion: Unilateral hand use of smartphone has adverse effect on CSA of the median nerve. The evidence from this study suggest that bilateral hands use of smartphone is recommended to reduce risk of Carpal tunnel syndrome
