Abstract
BACKGROUND: Prolonged use of the smartphone causes neck and shoulder pain. However, no study has yet evaluated the effects of sitting upright, combined with frequent breaks, eye rest and self-stretching on pain and EMG during smartphone use. OBJECTIVES: The purpose of the study was to compare pain and muscle activity between the control group (rest only) and the intervention group (rest combined with correct posture, eye rest and self-stretching) in smartphone use for 41.30 minutes. METHOD: Forty-four healthy females aged 18-25 years old were recruited and randomly divided into two groups. The body pain chart and Visual Analog Scale (VAS) were used to evaluate pain. Electromyography (EMG) was used to measure muscle activity of Cervical Erector Spinae (CES) and Upper Trapezius (UT) muscles. RESULTS: The results showed that overall pain and neck pain in the control group increased significantly after smartphone use for 20 min and continually increased to 41.30 minutes (p < 0.05). Overall pain and neck pain in the intervention group was significantly lesser than control group after smartphone use for 41.30 minutes (p < 0.05). In the control group, EMG of CES at 41.30 minute was significantly higher than that of at 0 min (p < 0.05). There was no significant difference in EMG of UT between the two groups. CONCLUSION: Conclusion smartphone user in the interventional group reported less pain when compared to control group after Smartphone use for 41.30 minutes. Therefore, the user aged 18-25 years should have a rest combined with correct posture, eye rest and self-stretching to prevent neck pain during prolonged smartphone use. © 2022 - IOS Press.
