Lumbar disc herniation generally adopts physical therapy such as bed traction combined with conservative treatment or surgical treatment such as oral or intravenous medication according to the severity of symptoms, the results of imaging examination and the therapeutic effect of patients. The functional exercise of patients during and after treatment mainly includes the following aspects: First, the straight leg lifting training of lower limbs. During the conservative treatment and after the operation, you can do lower limb strength exercise as soon as possible to stretch the nerve roots and reduce the adhesion around the nerve roots. Second, the lateral position lifts the legs to practice the strength of the lateral muscles of the lower limbs. Third, after the pain is relieved, you can exercise back muscle functions, such as three-point and five-point support and swallow movements. This will help to enhance the stability of the spine.
