Smartphone Addiction on the Biomechanical Properties of Thumb Muscles and Thumb Sensory Sensitivity

NCT07040267 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 36

Last updated 2025-07-02

No results posted yet for this study

Summary

This study will aim to assess the effects of smartphone addiction on thumb muscle biomechanics and sensory sensitivity among university students. The research will investigate whether excessive smartphone use leads to significant differences in muscle tone, stiffness, elasticity, and sensory discrimination capabilities.

Conditions

  • Smartphone Addiction
  • Thumb Injury

Interventions

DIAGNOSTIC_TEST

Thumb evaluations

There is no therapeutic or experimental intervention in this study. All procedures will be limited to diagnostic evaluations. The study will include non-invasive biomechanical and sensory assessments to compare the thumb muscle characteristics and sensory discrimination between smartphone-addicted and non-addicted university students. Specifically, muscle tone, stiffness, and elasticity will be measured using the MyotonPro™ device, and thumb sensory sensitivity will be evaluated using a Baseline Aesthesiometer with a two-point discrimination test. These assessments will be conducted during a single laboratory visit and will not involve any treatment, medication, or behavioral intervention. This is a purely observational study aimed at identifying potential associations between smartphone usage patterns and thumb neuromuscular or sensory changes.
