Smartphone addiction and neck muscle health
Investigation of the Effect of Smartphone Addiction on Neck Pain and the Structural and Mechanical Properties of Neck Muscles in Young Adults
Saglik Bilimleri Universitesi · NCT07038980
This project will see if smartphone addiction is linked to more neck pain and changes in neck muscle stiffness in healthy young adults.

What this trial studies
This is a cross-sectional observational project comparing healthy smartphone users aged 18–30 who meet validated thresholds for smartphone addiction with those who do not. Participants complete the Smartphone Addiction Scale–Short Form (SAS-SF), the Social Media Addiction Scale (SMAS), and the Neck Disability Index (NDI) to capture self-reported use and symptoms. Objective measurements of cervical muscle mechanical properties are taken with MyotonPRO (tone, stiffness, elastance) and pressure pain threshold is measured by algometry. People with diagnosed cervical spine pathology, neurological, rheumatological, or psychiatric disease, prior cervical surgery, or inability to cooperate are excluded.
Who should consider this trial
Good fit: Healthy adults aged 18–30 who actively use a smartphone, can follow instructions, and can give informed consent are ideal candidates.
Not a fit: People with diagnosed cervical spine pathology, neurological, rheumatological, or psychiatric disease, prior cervical surgery, or those unable to cooperate are unlikely to benefit from participating.
Why it matters
Potential benefit: If a link is confirmed, results could help design ergonomic and behavioral changes to prevent or reduce neck pain in young smartphone users.
How similar studies have performed: Other cross-sectional studies have reported associations between high smartphone use and neck pain, and technologies like MyotonPRO and algometry have been used successfully to detect muscle mechanical differences.
