| Abstract Background: 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. Aim of Study: This study was conducted to compare between bilateral and unilateral hand use of smartphone on cross sectional area of median nerve. Subjects and Methods: Fifty-six students aged 18-25 years old were recruited from Faculty of Physical Therapy Kafr El-Sheikh 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 results revealed that the paired t-test show significant increase in CSA of median nerve in unilateral than bilateral hands use of smartphone as t-value was 55,000 and p-value was p<.001. Conclusion: Unilateral hand use of smartphone has higher risk on CSA of median nerve so bilateral hands use of smart-phone is recommended than unilateral hand use to reduce risk of Carpal tunnel syndrome. | ||||
