Human Factors Inspired Chair Design II

主动坐姿是一种促进坐着时身体运动的新方法。传统的设计专注于**不稳定的平台，以促进运动，从而促进腿部和腰部肌肉的活动。**这些设计没有被广泛采用，因为在保持工作效率方面存在挑战，**专注于平衡和正确的坐姿。LifeForm家具制造商在他们的办公椅上采用了一种新的**‘Core-Flex’技术，可以帮助解决与长时间坐着相关的担忧**，并促进类似于行走的自然积极运动。Core-Flex技术允许**坐着的员工在保持工作效率的同时，通过腿部和腹肌进行移动。Core-Flex技术由分体式座椅盘组成，通过交替**主动脚踝和臀部运动来促进背部、骨盆和臀部运动，类似于行走动作。到目前为止，这种“主动坐”的方法还没有经验**证据支持将其纳入办公室座椅设计。最初的Engage项目是在新不伦瑞克大学**职业穿透实验室进行的，目的是评估和更好地**理解使用主动办公椅的人因结果。该项目为工业伙伴提供了研究设计修改。为了进一步加强设计，需要了解在自然无支撑站立过程中发生的**自然摇摆(移动)。这种运动方案需要**在Core-Flex设计修改中加入，以增加流向腰部和腿部的血流量，并**减少肌肉疲劳。这个项目将由Abert博士实验室的两名研究人员进行。**从多学科方法评估生物力学、神经肌肉和运动控制的结果**在整个项目中将与Core-Flex设计团队进行沟通。

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.
