Summary

This cross-sectional observational study investigates how smartphone addiction affects neck pain severity, pressure pain threshold, and mechanical properties of cervical muscles in healthy young adults. Two groups-those with and without smartphone addiction-are compared based on validated addiction scales and objective muscle assessments using MyotonPRO and algometry.

Detailed description

Smartphone addiction has become increasingly prevalent among young adults, often accompanied by poor posture and musculoskeletal complaints. This study aims to identify the differences in neck-related pain, disability, and mechanical muscle characteristics between addicted and non-addicted individuals. Participants are assessed using the Smartphone Addiction Scale - Short Form (SAS-SF), Social Media Addiction Scale (SMAS), Neck Disability Index (NDI), MyotonPRO for muscle tone/stiffness/elastance, and pressure algometry. The findings may contribute to the development of ergonomic and behavioral strategies for musculoskeletal health preservation in digital device users.

Conditions

• Smartphone Addiction
• Neck Pain

Interventions

Type	Name	Description
OTHER	Observational Assessment	Participants in both groups undergo a one-time diagnostic evaluation consisting of: Smartphone Addiction Scale - Short Form (SAS-SF) Neck Disability Index (NDI) MyotonPRO measurement of cervical muscle tone, stiffness, and elasticity Pressure pain threshold measurement using a handheld algometer Social Media Addiction Scale (SMAS) No therapeutic or behavioral intervention is applied. All procedures are non-invasive and conducted for observational purposes only.
