The prevalence of musculoskeletal disorders is high among teachers. Poor posture when writing on whiteboards is considered among the important causes of these disorders.
The present study aimed to evaluate an electromechanical rolling whiteboard for educational environments as an ergonomic intervention.
Thirty university lecturers volunteered to take part in the study. Participants performed a 5-minute writing task on a regular board and on the newly modified whiteboard in random order. The comfort and effectiveness of the boards and the perceived physical effort and posture of the participants were evaluated and compared by applying the verbal rating scale, Borg's rating of physical exertion scale, and rapid entire body assessment, respectively.
A total of 83.2% of participants reported the new whiteboard to be comfortable or more comfortable to use than the regular whiteboard, and 76.6% of them found the new whiteboard to be higher or much higher in effectiveness and usefulness in comparison with the regular whiteboard. The comfort and posture ratings revealed that exertion was significantly less and posture improved while writing on the new board as compared to its counterpart (p < 0.0001).
The new whiteboard increased user comfort, reduced physical effort, and improved posture, hopefully leading to a decreased number of work-related musculoskeletal disorders.
教师群体中肌肉骨骼疾病的发病率较高。在白板上书写时的不良姿势被认为是这些疾病的重要原因之一。
本研究旨在评估电动滚动白板作为一种教育环境下的人体工程学干预措施。
30 名大学讲师自愿参与本研究。参与者以随机顺序在常规板和新修改的白板上完成 5 分钟的书写任务。通过应用口头评分量表、Borg 体力活动等级量表和快速全身评估，分别评估和比较了这些板子的舒适性和有效性以及参与者感知到的体力消耗和姿势。
共有 83.2%的参与者报告说新的白板比常规白板使用起来更舒适或更舒适，76.6%的参与者认为新的白板在有效性和实用性方面比常规白板更高或高得多。舒适性和姿势评分显示，与常规白板相比，在新白板上书写时，用力明显减少，姿势也得到了改善（p<0.0001）。
新的白板提高了用户的舒适度，减少了体力消耗，改善了姿势，有望减少与工作相关的肌肉骨骼疾病的发生。
