The objective use of table top adjustable sit-stand desks has yet to be determined, due to the lack of an effective digital evaluation method. The objective of this study was to evaluate the impact of computer prompt software on table top sit-stand desks to determine if there was a difference in the frequency of desk position changes. This five month, pre-post pilot study on 47 university staff members used a novel USB accelerometer sensor and computer software reminders to continuously record and prompt increases in desk usage to promote physical activity at the workstation. During the baseline phase (3 months), desk usage data were continuously recorded for all workers. Following the baseline, the results from a two-month intervention of personalized computer reminders doubled the number of desk position changes per work day from 1 desk position change every 2 work days to 1 change every work day. Furthermore, those who changed desk positions once or twice a day increased from 4% to 36% from baseline to intervention. Overall, the intervention was encouraging, but longer intervention studies are warranted to determine if the desk usage behavior change can be improved and sustained for years and whether that change results in health gains.
由于缺乏有效的数字化评估方法，桌顶可调节坐立两用办公桌的客观用途尚未确定。本研究旨在评估计算机提示软件对桌顶坐立两用办公桌的影响，以确定在办公桌位置变化的频率上是否存在差异。这项为期五个月的、针对 47 名大学员工的预-后试点研究使用了一种新颖的 USB 加速计传感器和计算机软件提示，以持续记录和提示增加办公桌的使用，从而促进工作站的身体活动。在基线阶段（3 个月），为所有工作人员连续记录办公桌使用数据。在基线之后，为期两个月的个性化计算机提示干预措施使每个工作日的办公桌位置变化次数增加了一倍，从每两个工作日改变一次办公桌位置变为每天改变一次。此外，每天改变一次或两次办公桌位置的人数从基线到干预增加了 4%到 36%。总体而言，该干预措施令人鼓舞，但需要进行更长时间的干预研究，以确定是否可以改善和维持多年的办公桌使用行为变化，以及这种变化是否会带来健康收益。
