What this trial studies

This is an observational assessment of adults aged 18–45 that examines relationships between smartphone and video game use, reported pain, and upper extremity performance. Participants complete questionnaires about device use and symptoms and undergo physical and functional upper-limb assessments. People with major musculoskeletal surgery, neurological, systemic, rheumatic, or serious psychiatric conditions, active infections, or BMI ≥30 are excluded. All visits take place at a single site in Istanbul and no experimental treatments are given.

Who should consider this trial

Good fit: Adults 18–45 who volunteer, regularly use smartphones or video games, and have no major musculoskeletal, neurological, systemic, rheumatic, or serious psychiatric conditions and a BMI under 30 are ideal candidates.

Not a fit: People with recent major upper-body surgery or trauma, active systemic or rheumatic disease, serious neurological or psychiatric disorders, active infections, or BMI ≥30 are excluded and unlikely to receive direct benefit from participation.

Why it matters

Potential benefit: If a clear link is found, the results could help clinicians and users identify device-related risks and guide advice to reduce pain and improve arm/hand function.

How similar studies have performed: Previous observational studies have reported associations between high screen time and musculoskeletal pain or reduced upper-limb function, but findings are mixed and causal links remain unproven.
