摘要

跌倒，一直以來總是會讓人避之唯恐不及，尤其發生在老年人身上會造成更大的傷害，近年來在台灣的人口比率結構中，老年人口的比例越來越高，也顯示台灣也逐漸邁入了高齡化的社會。在高齡化社會中，跌倒所造成的傷害在老年人照護醫療比率中逐步增加。為了降低老年人跌倒風險，本研究計劃提出評估暨改善身體平衡機制系統，以提供醫療照護人員更多的資訊作為評估老年人身體平衡系統的參考。
本研究的目的是發展一套跌倒風險評估暨身體平衡機制改善系統。將以非侵入式量測生理訊號機以量測生理訊號來評估身體的平衡感，並且將開發震動鞋墊以物理性治療來改善身體的平衡系統。
研究中將著重於使用量測壓力重心的儀器取得數十位以年齡來區分的受測者之數據並使用一些數學分析方法(Multi-scale Entropy,MSE)配合經驗模組分解法(empirical mode decomposition, EMD)技術來評估受測者的平衡系統，再經由震動鞋墊的物理性刺激治療後以達到改善受測者自身的平衡系統。
希望藉由本研究的成果來提高評估老年人跌倒的準確性，使老年人能夠獲得更多的醫療照顧，並且能改善老年人自身的平衡系統以脫離跌倒的高危險群。

Falling down is an unpredictable accident and the caused injury can be serious; in particular, when it happens to the elderly, it can be fatal. In recent years, the proportion of the elderly population has increased in Taiwan, which shows that Taiwan has become an aging society. The elderly medical care ratio has increased gradually especially fall accident care. In order to reduce the possibility of falling, this research aims to evaluate the body balance system to provide nursing staff more information.
The purpose of this report is to develop a fall-risk assessment and balancing mechanism. We used a non-invasive measurement physiological signals machine to measure physiological messages and give physical therapy via vibrating insoles that improve the body’s balance system.
This research is focuses on the usage of the pressure-measured instruments to collect statistics from a number of subjects of different ages. Also, we use some mathematical analysis methods, such as Multi-scale Entropy (MSE), with empirical mode decomposition (EMD) to estimate their balance and stability systems. The subjects made progress due to physical stimulation treatment (wearing vibrating insoles).
We expect the results of this research to advance the accuracy of this subject, and the elderly will be able to obtain better medical care and not be among the high-risk groups of falling.
