The general principles of functional exercise for foot fracture are: gradual, persistent, combination of movement and static, exercise should start from a small amount, start from no weight, gradually put weight on and insist on exercise. When it’s time to move, when it’s time to be still, the combination of movement and stillness, early braking, to stop the activity, and later to strengthen the functional exercise. The specific method is: 1-2 weeks after the fracture, the fracture should be fixed with a splint or cast, and only the toe or knee or ankle joint should be moved. 2-3 weeks later, the joints of the foot should be moved gradually. 4-8 weeks later, you can gradually stand on the ground with a splint or cast, holding a double crutch, and slowly increase the weight. 8-12 weeks later, you can gradually increase the weight and slowly walk with a single crutch, and then abandon the crutch. Finally, you can walk with weight as a normal person.
