Walking still hurts 40 days after a broken foot can be rehabilitated, but it should be based on the criterion of not causing localized pain. Common training includes joint mobility training, muscle strength training, ankle stability training and so on. Before training, you need to be judged by a doctor to exclude ligament rupture, fracture and other problems. 1. Joint stability training: In the recovery period of foot sprain, you can passively pull the ankle joint with active movement of the ankle joint, joint mobility training, to prevent the problem of limited ankle joint movement. 2. Muscle strength training: during the recovery period of foot sprain, if the symptoms of pain and swelling have been relieved, muscle strength training can be carried out, such as the use of elastic bands on the foot resistance, active dorsiflexion and plantarflexion of the ankle joint, which can improve the strength of the muscles around the joint. 3. Ankle stability training: ankle stability training is needed during the recovery period of foot sprains to prevent the problem of foot re-sprains in the later stages, such as the option of standing on one leg to stimulate proprioception, which can enhance the stability of the ankle joint. Before the foot sprain is not fully recovered, pay attention to not too early strenuous exercise, to prevent re-sprain, usually in the exercise before a good warm-up exercise. It is recommended that patients carry out rehabilitation training under the guidance of physicians or rehabilitation therapists, so as to avoid re-injury caused by improper self-exercise.
