過去許多專家學者之研究指出因長期重覆性動作、過度用力或不當的工作姿勢，導致腱鞘、韌帶、神經及肌肉的反覆磨損或拉傷，容易造成累積性工作傷害。而目前現代生活及工作型態大多需仰賴電腦的使用，致使因使用電腦造成之累積性工作傷害的發生率較以往增加，因為當長期以坐姿方式於某些固定位置或範圍內重複操作鍵盤、滑鼠與螢幕之注視，此種靜態之作業活動時，容易造成肌肉骨骼症狀的傷害發生，而此種肌肉骨骼傷害較易發生於肩、頸、手腕部和背部。因此如何在使用滑鼠等相關點選輸入設備操作時能紓緩肩頸部的負荷，除了針對輸入設備做有效
的改良、教導正確的操作方式及固定頻率的休息時間外，亦可利用按摩的方式進行舒緩負荷及壓力。本研究針對因長時間使用電腦之上班族群最常引發之肩頸部疼痛症狀與動作牽引部位之肌群關係，藉由按摩之原理，利用按、揉…等動作於穴道之按摩方式，研發一種新型之肩頸按摩設備以減輕及預防電腦使用者或一般辦公室工作族群因長時間之低頭工作、注視電腦螢幕過久或長時操作滑鼠與鍵盤而引發之肩頸部疼痛症狀。

Research conducted by numerous experts and scholars in the past indicated that performing repetitive actions for extended periods of time, over-exertion or improper postures while working may lead to repetitive wearing or straining of tendon sheaths, ligaments, nerves and muscles and ultimately result in cumulative work injury. Due to contemporary
lifestyles and the nature of many occupations that are heavily reliant on the use of computers, the occurrence of cumulative work injuries related to computer use has been higher than ever. When a person sits for an extended period of time at a fixed position or area while performing repeated operations with a keyboard/mouse and stares at a monitor,
such static actions could easily lead to muscle or bone injuries, specifically at the shoulder, neck, wrist and back. One practical way to prevent such injury is to alleviate the stress at the shoulder-neck area for personnel whose job descriptions involve the operation of input devices (i.e. mouse and keyboard). Apart from effectively improving the
design of said input devices, instructing personnel to adopt proper operation habits, take regular breaks at fixed intervals, and massaging the key areas may also help to prevent injuries and alleviate stress. In this research, we have developed a new type of shoulder-neck massaging device that is capable of performing different massaging actions (such as pressing, rubbing and so forth) on the meridians. These actions are based on massaging principles and the relationship of physical discomfort and responsible muscle groups used in order to alleviate discomfort at the shoulder and neck area that might have been caused by prolonged working sessions in improper postures or habits (i.e. maintaining an improper
head-neck angle, looking at the computer screen for too long or using the mouse/keyboard for too long) intended for PC users and typical office workers who are most susceptible to suffer from such issues.
