Active seating is a new approach to promoting body movement while sitting. Traditional designs have focused**on non-stable platforms to promote motion and therefore engage muscle activity in the legs and lower back.**These designs have not been widely adopted due to the challenges in maintaining work productivity whie**concentrating on balance and proper sitting postures. Lifeform Furniture Manufacturers incorporates a new**'Core-Flex' technology in their office chairs that could help address concerns associated with prolonged sitting**and promote a natural active movement similar to walking. The Core-flex technology allows for movement for**the seated worker by engaging the legs and abdominals while remaining productive at the workplace. The**Core-Flex technology consists of a split seat pan that promotes back, pelvic and hip motion by alternating**active ankle and hip motion similar to a walking action. To date, this "active sitting" approach has no empirical**evidence to support its inclusion in office seat design. The original Engage project conducted in the**Occupational Perforamnce Lab at the University of New Brunswick had the goal of assessing and better**understanding the human-factor outcomes of using an active office chair. The project provided the industrial**partner with research design modifications. To further enhance the design requires the understanding of the**natural swaying (shifting) that occurs during natural unsupported standing. This movement protocol needs to**be incoprotated in The Core-Flex design modifications to increase blood flow to lower back and legs and**reduce muscle fatigue as well. This project will be conducted by two research students in Dr. Abert's lab.**Results from the multidisciplinary approach of assessing biomechanical, neuromuscular and motor control**aspects of active sitting will be communicated with the Core-Flex design team throughout the project.

主动座椅是一种促进身体运动的新方法。传统的设计侧重于不稳定的平台，以促进运动，从而参与腿部和下背部的肌肉活动。**这些设计并没有被广泛采用，因为在保持工作效率的同时**要注意平衡和正确的坐姿。Lifeform家具制造商在他们的办公椅中采用了一种新的“Core-Flex”技术，可以帮助解决长时间坐着的问题，并促进类似步行的自然活跃运动。Core-flex技术允许坐着的工人通过腿部和腹部活动，同时保持工作效率。Core-Flex技术由一个可拆分的座盘组成，通过踝关节和髋关节交替活动，促进背部、骨盆和髋关节的运动，类似于走路的动作。迄今为止，尚无实证证据支持将这种“主动坐着”的方法纳入办公室座椅设计。最初的Engage项目是在新不伦瑞克大学的职业绩效实验室进行的，其目标是评估和更好地理解使用活动办公椅的人为因素结果。该项目为工业合作伙伴提供了研究设计修改。为了进一步加强设计，需要理解在自然无支撑站立时发生的自然摇摆（移动）。这种运动方案需要与Core-Flex设计修改相结合，以增加下背部和腿部的血流量，并减少肌肉疲劳。这个项目将由两名研究生在艾伯特博士的实验室进行。**在整个项目过程中，将与Core-Flex设计团队进行多学科方法评估，评估活动坐姿的生物力学、神经肌肉和运动控制**方面的结果。
