Smartphone use causes upper extremity pain. A 12-week exercise and posture program significantly improved hand strength and reduced arm/hand disability in students, unlike the control group.
Area of Science:
- Ergonomics
- Physical Therapy
- Digital Health
Background:
- Repetitive smartphone use and poor posture lead to upper extremity pain.
- Texting and gaming are common activities contributing to these issues.
Purpose of the Study:
- To assess the impact of exercise and postural correction on smartphone users.
- Evaluate changes in Disabilities of the Arm, Shoulder, and Hand (DASH) scores.
- Measure improvements in hand grip and key pinch strength.
Main Methods:
- 100 university students were divided into experimental and control groups.
- The experimental group underwent a 12-week exercise and postural correction program.
- DASH scores, grip, and pinch strength were measured pre- and post-intervention.
Main Results:
- No initial differences between groups for DASH, grip, or pinch strength.
- The experimental group showed significant improvements in all measured outcomes (p < 0.05).
- The control group did not show significant changes.
Conclusions:
- Exercise and postural correction effectively mitigate smartphone-induced upper extremity issues.
- The combined approach improved hand strength and reduced disability.
- This intervention is beneficial for university students experiencing smartphone-related discomfort.
