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

Condition(s) studied

Investigational drug(s) / intervention(s)

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.

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.

Eligibility

Primary outcome measure(s)

• MyotonPro™ Muscle Assessment — Baseline
  This device will be used to assess muscle tone, stiffness, and elasticity in the abductor pollicis brevis, opponens pollicis, and flexor pollicis brevis muscles of both hands. Measurements will be performed with the participant in a standardized seated position.
