日本近年積極發展延緩老化之政策，以減輕國家的負擔。因此，臨床上提出了活動趨緩症候群的概念，其定義為因動作功能衰退而面臨接受照護的風險。若提早發現活動趨緩症候群並做治療，能改善或維持老年人的生活品質。本文探究日本活動趨緩症候群之經緯，檢測方法，相關文獻和改善方法。目前的研究發現，女性罹患活動趨緩症候群的機率高於男性。生理學研究發現，活動趨緩症候群者出現骨密度低，肌肉量低。此外，活動趨緩症候群者有較高的跌倒經驗，表現出低平衡能力，步行速度慢，步伐小，及生活品質較差。最後提出臺灣老年人健康促進政策及方案之建議。

Japan has recently taken measures against aging to reduce its impact on the country. Accordingly, clinicians have introduced the concept of locomotive syndrome, which identifies the risk of requiring nursing care due to a decline in motor function. If locomotive syndrome is detected and treated early, the quality of life in the elderly can be improved or maintained. In this paper, we describe the development, measurement methodology, relevant literature, and treatment of locomotive syndrome in Japan. Current studies have identified that women are more likely to develop locomotive syndrome than are men. Meanwhile, physiology studies have found that individuals with locomotive syndrome have a low bone density and muscle mass. Additionally, individuals who eventually develop locomotive syndrome often have experienced a high fall and exhibit poor balance, slow walking speed, small stride length, and poor quality of life. Finally, we offer insights into the development of beneficial health promotion policies and programs for elderly people in Taiwan.
