Abstract：
The purpose of this paper is to further understand current literature on prolonged sitting, sitting posture and active sitting solutions. This paper is divided into three sections: The first section (Part I) is a comprehensive overview of the literature on how a static prolonged seated posture can affect: spinal health, trunk posture, contact pressure/discomfort development and vascular issues. The second section (Part II) reviews and qualitatively compares the four working postures recognized in ANSI/HFES 100-2007: reclined sitting, upright sitting, declined sitting and standing. The final section (Part III) is a summary of research on active chairs that revolves around the two types of movement patterns: 1- sustaining continual movement over a range of postures, occasionally reaching neutral lordosis, and 2- maintaining high frequency and duration of daily light contractile activity in the legs (or lower limbs).
摘要：
本文的目的是进一步了解当前关于长时间坐着的文献，坐姿和主动坐姿解决方案。本文分为三个部分：第一部分（第一部分）是关于静态长时间坐姿如何影响的文献的全面概述：脊柱健康，躯干姿势,接触压力/不适发展和血管问题。第二部分（第二部分）回顾并定性比较了ANSI/HFES100-2007中认可的四种工作姿势：斜倚坐，直立坐着，拒绝坐着和站着。最后一部分（第三部分）是对活动椅子的研究的总结，这些活动椅子围绕着两种运动模式：1-在一系列姿势上保持连续运动，偶尔达到中性脊柱前凸，和2-维持腿（或下肢）的日常轻度收缩活动的高频率和持续时间。
