衰弱是一種常見的老年疾病，其特徵是多系統惡化和生理儲備的喪失。研究證實，衰弱與不良的健康結果有關，老年人的衰弱是一個動態的過程，身體的健康狀況會隨著時間有所起伏。物理治療師是運動方面的專家，也是健康的好幫手，在醫療保健系統的三個層面，每個層次都可以發揮其作用，透過正確訓練維持老年人的健康。長期照顧並不以疾病為導向，甚至不希望過度醫療化，所以並不隸屬於醫療體系，而是整合機構照顧（安養、養護）、社區照顧（日間照顧、關懷據點）及居家照顧（訪視家事），成立另一長期照顧體系，在這體系中，可以互通、轉換，必要時再連結醫療體系，所以不要以「生病」的思維「治療」他們的疾病，而是以「生活」的思維「照顧」他們生病引起的失能。雖然在超高齡時代的長期照顧領域內，充滿著物理治療師發揮的機會，卻也面臨著巨大而嚴峻的挑戰。

In this system, you can intercommunicate and convert, and if necessary, link the medical system, so don’t “treat” their dysfunction with the thought of disease, but “care” them with the thought of life. Disability caused by illness. Although in the long-term care of the super-age era, full of opportunities for PT to play, it also faces enormous and severe challenges.
