Human Factors Inspired Chair Design II

主动座椅是一种促进坐着时身体运动的新方法。传统的设计集中在非稳定平台上，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，还要注意平衡和正确的坐姿。Lifeform Furniture Manufacturers在他们的办公椅中采用了一种新的“Core-Flex”技术，可以帮助解决与久坐相关的问题 **，并促进类似于步行的自然主动运动。Core-flex技术允许 ** 坐着的工人通过腿部和腹部的活动来移动，同时保持工作场所的生产力。Core-Flex技术由一个分离式座椅板组成，通过交替进行类似于步行动作的主动踝关节和髋关节运动来促进背部、骨盆和髋关节的运动。到目前为止，这种“积极的坐姿”方法还没有经验证据支持它在办公室座椅设计中的应用。最初在新玩法大学职业绩效实验室进行的“参与”项目的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期间发生的自然摇摆（移位）。该运动方案需要 ** 在Core-Flex设计修改中整合，以增加下背部和腿部的血流量，并 ** 减少肌肉疲劳。该项目将由两名研究生在阿伯特博士的实验室进行。在整个项目过程中，将与Core-Flex设计团队沟通评估主动坐姿的生物力学、神经肌肉和运动控制 ** 方面的多学科方法的结果。

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.
