Smartphone Addiction and Isometric Strength of Rotator Cuff Muscles

Recruiting

• Conditions: Healthy Volunteer

• Registration Number: NCT06633081
• Lead Sponsor: Cairo University

Brief Summary

To investigate the relationship between smartphone addiction and isometric rotator cuff muscles strength among adults

Detailed Description

Smartphones play an important role in human life because they are used for communication, accessing the internet, and gaming. The rate of smartphone usage has increased over the last decade, as has the duration and frequency of use. according to one study, 79 percent of people aged 18 to 44 spent almost all of their time on their smartphones, with only two hours of the day spent without one.

No previous study has found a link between smartphone addiction and isometric Rotator Cuff muscular strength, to the authors' knowledge. Therefore, the primary purpose of this study will be to determine the relationship between smartphone addiction and isometric rotator cuff muscles strength.
