A kind of foot's rehabilitation system is suitable for detecting the motion state of a human foot, which includes: multiple radios label element, at least a radio-frequency readers and a rehabilitation data host with unification surface. The what surface is arranged in the grade RF tags element spaced apartly, and respectively the RF tag element includes one RF tag code. What human body foot is arranged in the radio-frequency readers, and when what is close to the grade RF tags element reads its RF tag code. The rehabilitation data host is electrically connected with the radio-frequency readers, and the RF tag code of the grade RF tags element is read through the radio-frequency readers, and synchronously what record reads the complex time point of the grade RF tags code, then calculates according to the grade RF tags code and the equi-time point rehabilitation data of the motion state of a correlation what human body foot.一種腳部復健系統，適用於配合一表面，偵測一人體腳部的運動狀態，該腳部復健系統包含：複數射頻標籤元件、至少一射頻讀取器，及一復健資料主機。該等射頻標籤元件彼此相間隔地設置於該表面，各該射頻標籤元件包括一之射頻標籤碼。該射頻讀取器設置於該人體腳部，並於接近該等射頻標籤元件時讀取其射頻標籤碼。該復健資料主機與該射頻讀取器電連接，並透過該射頻讀取器讀取該等射頻標籤元件之射頻標籤碼，並同步地於記錄讀取到該等射頻標籤碼的複數時間點，再依據該等射頻標籤碼及該等時間點計算出一相關於該人體腳部之運動狀態的復健數據。
