Foot drop is usually treated with bracing and passive rehabilitation, and should be treated as soon as it is detected. Rehabilitation of foot drop mainly relies on the wearing of braces, which can be put on when the patient wants to walk, so as to maintain the balance of the body and effectively reduce the risk of falling. The passive rehabilitation of foot drop mainly refers to the passive stretching of the foot under the guidance of a professional physician. It can also be combined with the treatment of letting the patient stand on an inclined board, because when standing on an inclined board the foot drops down and the board goes up, which can actually achieve the purpose of passive stretching, and it can be combined with the exercise of tibialis anterior muscle strength.
