The study aims were, in a population of university students, staff, and faculty (n = 140), to: 1) determine the distribution of seven measures of mobile device use; 2) determine the distribution of musculoskeletal symptoms of the upper extremity, upper back and neck; and 3) assess the relationship between device use and symptoms. 137 of 140 participants (98%) reported using a mobile device. Most participants (84%) reported pain in at least one body part. Right hand pain was most common at the base of the thumb. Significant associations found included time spent internet browsing and pain in the base of the right thumb (odds ratio 2.21, 95% confidence interval 1.02-4.78), and total time spent using a mobile device and pain in the right shoulder (2.55, 1.25-5.21) and neck (2.72, 1.24-5.96). Although this research is preliminary, the observed associations, together with the rising use of these devices, raise concern for heavy users.
本研究旨在对大学生、教职工群体（n=140）进行调查：1）确定七种移动设备使用情况的分布情况；2）确定上肢、上背部和颈部肌肉骨骼症状的分布情况；3）评估设备使用与症状之间的关系。140 名参与者中有 137 名（98%）报告使用了移动设备。大多数参与者（84%）报告至少有一个身体部位疼痛。右手拇指根部疼痛最为常见。发现的显著关联包括上网浏览时间与右手拇指根部疼痛（比值比 2.21，95%置信区间 1.02-4.78），以及使用移动设备的总时间与右肩（2.55，1.25-5.21）和颈部（2.72，1.24-5.96）疼痛之间的关联。尽管这项研究尚属初步，但观察到的关联，以及这些设备的使用率不断上升，令重度使用者感到担忧。
