Postpartum short legs may or may not recover on their own, and most patients can recover after effective postnatal exercise and treatment. Postpartum short and long legs are mainly due to the imbalance of the strength of both lower limbs caused by the extrusion of the pelvis during late pregnancy or labor, some women can recover slowly on their own, and some women can promote recovery through some exercise methods. After delivery, you can restore the balance of lower limb strength through appropriate exercise, such as running, yoga, swimming, etc. In addition, with the lower limb muscle traction, the lower limb muscle balance can be restored. In addition with the lower limb muscle traction and stretching training, joint correction training, wearing orthopedic appliances, etc., will help the condition to recover. Postpartum long and short legs are not the same as those caused by some diseases, such as sacroiliac joint subluxation, scoliosis, hip joint lesions and so on. Many mothers have the basis of these diseases before pregnancy, and the condition progressively aggravates after pregnancy and delivery, resulting in postnatal asymmetry of both lower limbs. These cases must be improved imaging examination, clear the cause of the disease and then active treatment. In short, if you can’t recover on your own, we recommend that you go to a regular hospital as soon as possible, complete the examination, make a differential diagnosis with the relevant diseases, and then actively treat and regulate the condition under the guidance of the doctor.
