This study explored the prevalence and work interference (WI) of upper extremity musculoskeletal discomfort (UEMSD) and investigated the associations of individual and work-related risk factors and using a notebook stand or docking station with UEMSD among symptomatic occupational notebook personal computer (PC) users.
The participant group included 45 Turkish occupational notebook PC users.
The study used self-reports of participants. The Turkish version of the Cornell Musculoskeletal Discomfort Questionnaire (T-CMDQ) was used to collect symptom data.
UEMSD prevailed mostly in the neck, the upper back, and the lower back with prevalence rates of 77.8%, 73.3%, and 60.0% respectively, and with WI rates of 28.9%, 24.4%, and 26.7% respectively. Aggregated results showed that 44% of participants reported WI due to UEMSD in at least one body region. Significant risk factors were: being female, being aged <31 years, having computer work experience <10 years, and physical discomfort during computer use.
UEMSD prevalence and WI rates were considerable in the neck, the upper back, and the lower back. Significant associations between certain risk factors and UEMSD were identified, but no association was found between using notebook stand and docking station and UEMSD among participants.
本研究探讨上肢肌肉骨骼不适（UEMSD）的患病率及工作干扰（WI）情况，并调查有症状的职业笔记本电脑个人电脑（PC）用户中个体及工作相关风险因素以及使用笔记本电脑支架或扩展坞与UEMSD之间的关联。
参与者组包括45名土耳其职业笔记本电脑PC用户。
本研究采用参与者的自我报告。使用康奈尔肌肉骨骼不适问卷土耳其语版（T-CMDQ）收集症状数据。
UEMSD主要出现在颈部、上背部和下背部，患病率分别为77.8%、73.3%和60.0%，工作干扰率分别为28.9%、24.4%和26.7%。汇总结果显示，44%的参与者报告至少在一个身体部位因UEMSD出现工作干扰。显著风险因素包括：女性、年龄<31岁、计算机工作经验<10年以及计算机使用过程中的身体不适。
颈部、上背部和下背部的UEMSD患病率及工作干扰率相当高。确定了某些风险因素与UEMSD之间的显著关联，但在参与者中未发现使用笔记本电脑支架和扩展坞与UEMSD之间存在关联。
