The present invention is an ankle-foot orthosis with a flexible joint. It is consisted of the feet plate, shank sleeve, and the flexible joint. The feet plate supports the foot of the stroke patient when using the AFO and help the patient toe off in the pre-swing phase of a gait cycle. The shank sleeve ties at the shank by the elastic belts. The flexible joint locates near the ankle and link between the feet plate and shank sleeve. The flexible joint has an asymmetric structure, which has one front notch and several back notches to limit the bending angle of the plantar flexion and dorsi-flexion of the ankle. Besides, the feet plate has a lift in the front side for easily toe off.一種具撓性關節之足踝矯正器，係包含包含一足底板，一固定小腿之腿套及一撓性關節。其中，足底板可托住足底，並提供前進之被動推進。腿套可穿於小腿上，並輔以綁帶，用以固定足踝矯正器。兩者連接部分為一撓式關節，結合位置位於踝關節近緣。其中可撓式關節其向腳趾方向之前側，有一開口，開口與踝關節高度一致，後側向腳跟之方向，為複數個開口，此結構可調整背屈與蹠屈活動範圍。足底板前側腳趾端翹起，可於病患行走時，協助其向前推進，使行走步伐擺盪更流暢。
