Background: The posture while using smartphone in school-aged children is at risk on occurring musculoskeletal symptoms. The purpose of this study is to study the postures while using a smartphone and the factors related to the abnormalities of the musculoskeletal symptoms of school-aged children.
Method: Experimental study is a method of this research. The samples were 233 school-aged children in Nakhon Si Thammarat, Thailand. Multi-stage sampling and data collection consisted questionnaire for the musculoskeletal symptoms by applying from the Nordic Musculoskeletal Questionnaire, ISO 11226: 2000 Ergonomics-Evaluation of static postures, which was a smartphone using posture evaluation form with data analysis using percentage, mean, standard deviation and Chi square.
Result: The smartphone usage posture are mostly a lying position, which is 52.4%. 91.5 % of children has unacceptable risky smartphone usage posture. Mostly, the lying position has various organs tilted at angles, compared to the body's symmetrical axis, rather than the sitting position. The school-aged children had a prevalence of musculoskeletal symptoms of 20.2%, with the lying position having a higher rate of musculoskeletal symptoms, which is 10.7%. The smartphone usage posture is statistically significant correlated with the symptoms occurring in the head area. The risk of ergonomics and the musculoskeletal symptoms are statistically significant.
Conclusion: The smartphone usage posture among students is at high risk especially lying position and has a chance of a musculoskeletal symptoms, higher than the sitting position. Educating to provide knowledge about safe use of smartphones to students, parents and relevant government agencies is very important.
