What this trial studies
This observational study aims to explore the relationship between smartphone addiction and the isometric strength of rotator cuff muscles in healthy adults aged 18 to 30. Participants will be required to use smartphones for more than four hours daily. The study will utilize a handheld dynamometer to measure muscle strength. By examining this connection, the research seeks to provide insights into how excessive smartphone use may impact physical health, particularly in the shoulder region.
Who should consider this trial
Good fit: Ideal candidates for this study are healthy adults aged 18 to 30 who use smartphones for more than four hours a day.
Not a fit: Patients with existing shoulder conditions or a history of musculoskeletal injuries will not benefit from this study.
Why it matters
Potential benefit: If successful, this study could help identify potential health risks associated with excessive smartphone use, leading to better preventive strategies.
How similar studies have performed: No previous studies have established a link between smartphone addiction and isometric rotator cuff muscle strength, making this research novel.
Eligibility criteria
Show full inclusion / exclusion criteria
Inclusion Criteria: \- 1- This study will comprise healthy volunteers between the ages of 18 and 30 who needed to use a smart phone. 2- Subjects who put in more than 4 hours per day using smartphone. Exclusion Criteria: * Patients will rule out if 1. They had any medical condition that could cause shoulder pain (such as impingement, subacromial bursitis, rotator cuff damage, or traumatic or degenerative supraspinatus tendonitis). 2. Anyone with a positive Neer sign, a positive Hawkins sign, discomfort during shoulder elevation, pain at the location of the rotator cuff tendon, pain with resisted isometric shoulder abduction, or a history of pain in the C5 dermatome will be ruled out. 3. Any individual who had previously suffered a musculoskeletal injury or surgery that could have influenced the measurement will be also eliminated.
