The amount of spontaneous movement during seated office work was estimated by analysing the tilting movements of a tiltable office chair. Both movement frequency and amplitude range were considered. The seat inclinations and subjective acceptability were also recorded. The seat was moved more frequently and with a greater range when adjusted 6 cm above popliteal level compared to 1 cm below, or when the backrest was pushed anteriorly or posteriorly compared to a middle position. The greatest acceptability occurred with the highest seat adjustment and the backrest in the middle position. Typing or desk-work influenced movement to a similar extent.
通过分析可倾斜办公椅的倾斜运动来估计坐姿办公期间的自发运动量。同时考虑了运动频率和幅度范围。还记录了座椅倾斜度和主观可接受性。与腘窝水平以下1厘米相比，当座椅调整到腘窝水平以上6厘米时，或者与中间位置相比，当靠背向前或向后推时，座椅移动得更频繁，范围也更大。在最高座椅调整和靠背处于中间位置时，可接受性最高。打字或伏案工作对运动的影响程度相似。
