Flat feet can be restored through plantar muscle strength training, athletic stretching, and wearing orthopedic insoles. Patients with serious conditions need to be treated by surgery or manual deformity correction. 1. Plantar muscle strength training: can be carried out under the guidance of a professional rehabilitator, common exercise methods include pinching things with the toes, doing toe flexion, walking with the toes, etc., which can effectively strengthen the strength of the patient’s intramuscular muscles and improve the patient’s symptoms. 2. Exercise stretching: under the guidance of the rehabilitator, stretching exercise can be carried out by stepping on the foam shaft on the soles of the feet, which is conducive to relieving the plantar fascia tension caused by flat feet and improving the symptoms of flat feet. 3. Wearing orthopedic insoles or orthopedic shoes: orthopedic insoles or orthopedic shoes can change the distribution of plantar pressure, help patients with flat feet to form normal arches, and enhance the elasticity of plantar ligaments, which can well correct flat feet. It is recommended that patients with flat feet should consult a doctor in time and under the guidance of a professional doctor, do not blindly train on your own to avoid the adverse consequences.
