“…Unsurprisingly, this study revealed that all of the student sample own smartphones. Based on their age group, these students adopt a static and flexed spinal posture while texting on mobile phones [12], which is the most common posture that contributes to neck pain [13]. To the best of our knowledge, this is the first study to use the NRS-11 pain severity score of 4 as a threshold value for increasing alertness to neck pain.…”

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 signi cant correlated with the symptoms occurring in the head area. The risk of ergonomics and the musculoskeletal symptoms are statistically signi cant. 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.

Background: Technology is prevalent in almost every aspect of life, from handheld phones to computers. Increases in cervical flexion can cause a strain on the neck and muscles of the upper extremity. Objective: To examine the effect of 30 minutes of cervical flexion at 45 degrees. It was hypothesized that muscle strength will decrease after flexion, and there would be no significant differences between dominant and nondominant arms or genders. Study design: Twenty-four participants (12 male, 12 female) (n = 24; height = 173.1 + 9.3 cm; weight = 73.33 + 22.58kg) were measured before and after cervical flexion using a MicroFET2 Hand Held Digital Muscle Tester to test the middle deltoid, biceps brachii, and triceps brachii of each arm. Results: Compared to pre-measures significant differences were found in both middle deltoids and both biceps brachii, but not in either triceps brachii (p < 0.05). Overall no limited significant differences were found between genders of muscles of either arm. Significant differences (p < 0.05) were found in the dominant biceps brachii, non-dominant biceps brachii, dominant triceps brachii, dominant deltoid, and non-dominant deltoid. Conclusion: These results suggest that a normal daily degree of cervical flexion will decrease some upper extremity strength over the course of 30 minutes.
