Young children (ages 3 to 5) are using mobile touchscreen technology, including tablet computers, yet little is known on the potential musculoskeletal and physical activity implications of its use. This within-subject laboratory study (n = 10) examined head, trunk and arm postures, upper trapezius muscle activity, and total body and upper limb physical activity during playing with tablets compared to during TV watching and playing with non-screen toys. Overall, this study found that during tablet play children had greater mean head, trunk and upper arm angles compared to both TV watching and toy play. Conversely, compared to toy play, children playing with tablets had lesser trunk, upper arm and elbow postural variation, lesser trapezius activity, more time sitting and lesser physical activity. Thus, to minimize potential musculoskeletal and sedentary risks, non-screen toy play should be encouraged and education and guidelines provided for parents and caretakers to support wise use of tablets.
幼儿（3 至 5 岁）正在使用移动触屏技术，包括平板电脑，但对于其使用可能对肌肉骨骼和身体活动产生的影响知之甚少。本项个体实验室研究（n=10）比较了儿童在使用平板电脑、观看电视和玩非屏幕玩具时的头部、躯干和手臂姿势、上斜方肌活动以及全身和上肢的身体活动。总的来说，这项研究发现，与观看电视和玩非屏幕玩具相比，儿童在使用平板电脑时头部、躯干和上臂的平均角度更大。相反，与玩非屏幕玩具相比，玩平板电脑的儿童躯干、上臂和肘部姿势变化更小，上斜方肌活动更少，坐着的时间更多，身体活动更少。因此，为了尽量减少潜在的肌肉骨骼和久坐风险，应鼓励儿童玩非屏幕玩具，并为家长和看护者提供教育和指导，以支持明智地使用平板电脑。
