Inversion refers to the movement of the ankle joint in the direction of the big toe, and inversion refers to the movement of the ankle joint in the direction of the little toe. As shown in FIG. 7, the movement of the ankle joint in the third direction R3 based on the central axis NF′ centered on the leg of the wearer P is called eversion, and the fourth direction ( R4) to exercise the ankle joint is called inversion. In normal ankle joint movement, the circumference can move up to the third reference line (EF) based on the neutral line (NF), and the inversion angle can move up to the fourth reference line (IF) based on the neutral line (NF).

As an embodiment, when the length of the first wire S1 is shortly adjusted through the first dial unit 310, it is effective as pulling the muscle of the portion where the first wire S1 is located. Therefore, the foot can move from the neutral line (NF') to the third reference line (EF). Similarly, when the length of the second wire S2 is shortly adjusted through the second dial portion 320, there is an effect as pulling the muscle of the portion where the second wire S2 is located. Therefore, the foot can move from the neutral line (NF') to the fourth reference line (IF).

Foot Drop Aka, patients with foot drop disease, have muscle weakness due to muscle abnormality or nerve compression or damage, and do not lift the ankle, pull the instep toward the body, and have the symptoms of the foot falling down. These foot drop patients may occur not only when the foot falls down, but also when the foot is turned left or right due to hemiplegia. In this case, for the treatment and rehabilitation of the symptoms, it is very important to balance the wrong feet due to hemiplegia while simultaneously pulling up the feet falling from the foot drop patients.

Foot and foot brace 20 according to an embodiment of the present invention by adjusting the length of the wire portion (WU') itself by the dial portion 220 can adjust the dorsiflexion angle and vertebral angle of the ankle muscle of the foot drop patients. In addition, the length of the first wire (S1) and the second wire (S2) can be individually adjusted by the first dial unit 310 and the second dial unit 320, whereby the ankle muscles of the foot drop patients You can adjust the inversion angle and inversion angle of.
