The present invention provides a biofeedback-type lower limb rehabilitation treatment device and system. The lower limb rehabilitation treatment device includes a weight measurement module, a microprocessor module, an alarm module, and a display module. The microprocessor module includes a statistical unit capable of calculating a total weight from the weight measurement module, a comparison unit capable of outputting an alarm signal when the total weight is larger than a dangerous upper limit or smaller than an ineffective lower limit, and an analysis unit capable of outputting a ratio data of effective weight. The alarm module can be driven by the alarm signal for outputting an alarm message in real time. The display module can display the total weight in real time. By using the microprocessor module, the invented design is capable of feeding back and outputting in real time the total weight of each step and the total rehabilitation impact of each treatment during a rehabilitation treatment. As a result, the invention can be used to train a person under rehabilitation in controlling the load-receiving power of lower limb suffering from bone fracture, thereby increasing the rehabilitation effect of lower limb suffering from bone fracture.一種生物回饋式下肢復健訓練裝置與系統，該下肢復健訓練裝置包含一載重量測模組、一微處理模組、一警示模組及一顯示模組。微處理模組包括一可總計載重量測模組之載重總值的統計單元、一可於載重總值大於危險上限值或小於無效下限值時輸出警示訊號的比較單元，及一可輸出有效載重比例資料之分析單元。警示模組可被警示訊號驅動而即時輸出警示訊息，顯示模組可即時輸出載重總值。透過微處理模組可於復健時，即時回饋輸出每一步伐之載重總值及每一療程之復健衝量總值的設計，能訓練復健者控制骨折下肢的載重力量，可提高骨折下肢的復健效果。
