Document holder is used as a remedy to address occupational neck pain among computer users. An understanding on the effects of the document holder along with other work related risk factors while working in computer workstation requires attention. A comprehensive knowledge on the optimal location of the document holder in computer use and associated work related factors that may contribute to neck pain reviewed in this article. A literature search has been conducted over the past 14 years based on the published articles from January 1990 to January 2014 in both Science Direct and PubMed databases. Medical Subject Headings (MeSH) keywords for search were neck muscle OR head posture OR muscle tension' OR muscle activity OR work related disorders OR neck pain AND/OR document location OR document holder OR source document OR copy screen holder.Document holder placed lateral to the screen was most preferred to reduce neck discomfort among occupational typists. Document without a holder was placed flat on the surface is least preferred. The head posture and muscle activity increases when the document is placed flat on the surface compared to when placed on the document holder. Work related factors such as static posture, repetitive movement, prolong sitting and awkward positions were the risk factors for chronic neck pain. This review highlights the optimal location for document holder for computer users to reduce neck pain. Together, the importance of work related risk factors for to neck pain on occupational typist is emphasized for the clinical management.
文件架被用作一种缓解计算机使用者职业性颈部疼痛的方法。在计算机工作站工作时，了解文件架的作用以及其他与工作相关的风险因素很有必要。本文回顾了关于计算机使用中文件架的最佳位置以及可能导致颈部疼痛的相关工作因素的全面知识。在过去14年里，基于1990年1月至2014年1月在Science Direct和PubMed数据库上发表的文章进行了文献检索。搜索的医学主题词（MeSH）关键词为颈部肌肉或头部姿势或肌肉紧张或肌肉活动或工作相关疾病或颈部疼痛以及/或者文件位置或文件架或原始文件或复制屏幕架。对于职业打字员来说，将文件架放置在屏幕侧面最有助于减轻颈部不适。没有文件架的文件平放在桌面上是最不可取的。与放在文件架上相比，文件平放在桌面上时，头部姿势和肌肉活动会增加。与工作相关的因素，如静态姿势、重复动作、长时间坐着和别扭的姿势，是慢性颈部疼痛的风险因素。这篇综述强调了计算机使用者文件架的最佳位置以减轻颈部疼痛。同时，强调了与工作相关的风险因素对职业打字员颈部疼痛的重要性，以用于临床管理。
