上下床是日常生活中不可或缺的動作，但隨著年齡增長造成生理機能退化，造成活動能力下降，使起床不便。由於起床會使身體重心移動，容易造成高齡者重心不穩或姿勢性低血壓導致失去平衡感而造成跌倒，因此可藉由床邊扶手降低高齡者在床邊跌倒或無法起身的風險。然而目前市面上各式各樣床邊扶手滿足高齡者的需求，但床邊扶手卻也容易因為錯誤的使用方式和不合適的位置造成傷害。
本研究針對高齡者起床姿勢操作及床邊扶手使用配置範圍進行探討，首先觀察不同年齡在無扶手起床和使用扶手的起床操作及受測者主觀施力位置的差異，並使用扶手主觀感受評量探討高齡者使用床邊扶手更容易起床的姿勢，再探討不同年齡和人體尺寸對於高齡者使用床邊扶手配置影響並找出合適的擺放位置。結果發現高齡者會較年輕人使用更多上肢和腿部力量，此起床操作可幫助使用扶手起床更容易。不同年齡情況下對扶手擺放的角度和距離有顯著影響，同樣地高齡者的不同人體尺寸會造成扶手擺放角度具有顯著差異。本研究會提出高齡者使用床邊扶手建議起床的姿勢以及建議擺放位置以降低高齡者在起床時所造成的跌倒風險，並可做為未來設計輔具上有重要的依據。

Getting into and out of bed is one of the most important activities of daily living. As people grew older, deterioration in mobility caused by age would make it difficult to get up from bed. Falling happens on changing body center because of lose balance and low blood pressure. Therefore, elderly can use bed rails to decrease falling risks and provide support when elderly have difficulty getting into and out of bed. Although various types may be used depend on elderly needs, bed rails may lead to accidents because wrong methods and improper installation. The main purpose of this study focuses on bed mobility for elderly and the location of bed-rails. First, the difference between healthy young adults and older adults in movement and point of application for getting up from bed was observed. Second, subjective ratings were applied to determine how to use bed rails to get up from bed easier for elderly.Third, the impact of age and body dimension for elderly on the location of bed-rails was assessed. The result shows that older adults using upper limbs and strength of lower extremities more frequently than healthy young adults to demonstrate the movement can make older adults get up from bed using bed rails easier. It was observed that age significantly influence the angle and distance of bed-rails. Similarly, the body dimension for elderly caused significantly difference on the angle of bed-rails. Finally, this study suggested the used of bed with bed-rails and the suitable location of bed-rails for better posture and to minimize risk of falling when getting up from bed. The finding can be used as a principle for the design of bed-rails and to decrease falling risks when getting into and out of bed for elderly.
