The present study aimed to compare the static and dynamic sitting posture during computer work among symptomatic and asymptomatic office workers in actual work environment.
Seventy female office workers were divided into two groups: asymptomatic (n = 35) and symptomatic (n = 35). Subsequent to this classification, adjustments to their respective workstations were implemented in accordance with Occupational Safety and Health Administration (OSHA) guidelines. The assessment of neck (CV) and shoulder (FS) angles were conducted during both a typical seated posture and at intervals of 20 min over a duration of 3 h of computer work.
The asymptomatic group had a range of age from 26 to 40 years, a BMI of 21.11 ± 2.14, and a working experience ranged from 1 to 16 years. In contrast, the symptomatic group had an age range from 24 to 40 years, a BMI of 21.12 ± 2.27, and a working experience ranged from 3 to 16 years. During static sitting posture, significant differences were observed in both CV (p = 0.01) and FS angles (p = 0.00) between the two groups. Additionally, during computer work sessions lasting for 3 h, a significant time effect (p = 0.00) was noted for the CV angle. Furthermore, the FS angle exhibited significant group (p = 0.00), time (p = 0.00), and interaction (p = 0.00) effects during work.
This study underscores the development of neck flexion during prolong working in both groups. In addition, asymptomatic group experienced a progression more rounded shoulder during a 3-h working period. Prolonged periods of sitting and computer use appear to have adverse effects on neck and shoulder health, underlining the importance of implementing measures to mitigate these effects.
本研究旨在比较有症状和无症状上班族在实际工作环境中进行电脑操作时的静态和动态坐姿。
70名女性上班族被分为两组：无症状组（n = 35）和有症状组（n = 35）。分组后，根据美国职业安全与健康管理局（OSHA）的指导方针，对她们各自的工作站进行了调整。在典型坐姿以及3小时电脑工作期间每隔20分钟对颈部（CV）和肩部（FS）角度进行评估。
无症状组年龄范围为26至40岁，体重指数为21.11±2.14，工作经验为1至16年。相比之下，有症状组年龄范围为24至40岁，体重指数为21.12±2.27，工作经验为3至16年。在静态坐姿时，两组之间的CV（p = 0.01）和FS角度（p = 0.00）均存在显著差异。此外，在持续3小时的电脑工作期间，CV角度存在显著的时间效应（p = 0.00）。此外，FS角度在工作期间表现出显著的组间效应（p = 0.00）、时间效应（p = 0.00）和交互效应（p = 0.00）。
本研究强调了两组在长时间工作期间颈部屈曲的发展。此外，无症状组在3小时的工作期间出现了更圆肩的进展。长时间坐着和使用电脑似乎对颈部和肩部健康有不利影响，突出了采取措施减轻这些影响的重要性。
