Fractures of the second metatarsal can be treated by gradual motor function exercises, including muscle strength training, joint mobility training and standing balance training. 1. Muscle strength training: After the fracture of the second metatarsal, the lower limb muscles should be rested in the early stage, and isometric contraction can be used for muscle strength training to prevent muscle atrophy without causing the fracture end to move. 2. Joint mobility training: after the second metatarsal fracture, it may affect the range of motion of the local joints, so in the process of fracture recovery, it is necessary to carry out joint mobility training, such as passive stretching or active contraction, in order to avoid the problem of soft tissue adhesion. 3. Standing balance training: after the second metatarsal fracture has healed and stabilized, it is necessary to carry out standing balance training, and gradually carry out weight-bearing on the affected side of the lower limbs to improve the standing balance function, so as to prevent gait abnormality or unstable posture in the later stage. It is recommended that patients follow the doctor’s instructions during the recovery period, pay attention to supplemental nutrition, do not blindly exercise to avoid adverse consequences.
