Dynamic chairs have the potential to facilitate movements that could counteract health problems associated with sedentary office work. This study aimed to evaluate whether a dynamic chair can increase movements during desk-based office work.
Fifteen healthy subjects performed desk-based office work using a dynamic office chair and compared to three other conditions in a movement laboratory. In a field study, the dynamic office chair was studied during three working days using accelerometry.
Equivocal results showed that the dynamic chair increased upper body and chair movements as compared to the conventional chair, but lesser movements were found compared to standing. No differences were found between the conditions in the field study.
A dynamic chair may facilitate movements in static desk-based office tasks, but the results were not consistent for all outcome measures. Validation of measuring protocols for assessing movements during desk-based office work is warranted.
动态座椅有可能促进一些动作，这些动作可以抵消与久坐办公相关的健康问题。本研究旨在评估动态座椅是否能增加伏案办公期间的身体活动。
15名健康受试者使用动态办公椅进行伏案办公，并在运动实验室与其他三种情况进行比较。在一项实地研究中，使用加速度计在三个工作日对动态办公椅进行了研究。
结果不明确，表明与传统座椅相比，动态座椅增加了上半身和座椅的活动，但与站立相比活动较少。实地研究中各情况之间未发现差异。
动态座椅可能有助于在静态伏案办公任务中增加活动，但并非所有结果测量指标的结果都一致。有必要对评估伏案办公期间活动的测量方案进行验证。
