About this study
Official title: The Effect of Smartphone Use on Neck Flexion Angle and Hand Grip Power Among Adolescence
Excessive smartphone use can disrupt your sleep, which can have a serious impact on your overall mental health. It can impact your memory, affect your ability to think clearly, and reduce your cognitive and learning skills. Encouraging self-absorption.
Read the detailed description
Persistent failed attempts to use cell phone less often. Preoccupation with smartphone use. Turns to cell phone when experiencing unwanted feelings such as anxiety or depression. Excessive use characterized by loss of sense of time.
Nomophobia-an abbreviation of "no-mobile-phone-phobia"-is also called "cell phone addiction." Symptoms include: Experiencing anxiety or panic over losing your phone. Obsessively checking for missed calls, emails, and texts.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
the neck flexion angle (time frame: the neck flexion angle at day 0). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04715009, which also lists 4 linked publications.
