A novel active office chair (Movably Pro) was designed to facilitate frequent sit-stand movement 1) through auditory and tactile prompts and 2) with minimal-to-no work surface adjustment when transitioning. The purpose of this study was to compare lumbopelvic kinematics, discomfort, and task performance between the novel chair and traditional sitting/standing. Sixteen participants completed three separate 2-h sedentary exposures. Although participants transitioned every 3 min between sitting and standing with the novel chair, productivity was not affected. When standing in the novel chair, the lumbopelvic angles fell in between traditional sitting and standing (p < 0.01). Movement and/or postural changes that occurred with the novel chair reduced low back and leg discomfort for pain developers (PDs) (p < 0.01). All participants classified as PDs in traditional standing were non-PDs with the novel chair. This intervention was effective in reducing sedentary time without the time loss associated with desk movement.
一种新型主动办公椅(Movably Pro)旨在通过听觉和触觉提示促进频繁的坐站转换,并在转换时尽量减少对工作表面的调整。本研究旨在比较新型椅子与传统坐站时的腰骨盆运动学、不适和任务表现。16 名参与者完成了三次单独的 2 小时久坐暴露。尽管参与者在新型椅子上每隔 3 分钟转换一次坐姿和站姿,但生产力并未受到影响。当参与者站在新型椅子上时,腰骨盆角度介于传统坐姿和站姿之间(p<0.01)。新型椅子上的运动和/或姿势变化减少了腰背和腿部不适,减轻了腰背疼痛患者(PDs)的疼痛(p<0.01)。在传统站立时被归类为 PDs 的所有参与者在新型椅子上均不属于 PDs。这种干预措施可有效减少久坐时间,而不会像办公桌移动那样导致时间损失。
