Inability to walk often involves three major factors: 1) problems with innervation, 2) problems with muscle strength in the lower extremities, and 3) structural abnormalities in the lower extremities, such as fractures or dislocations due to bone and joint disease, resulting in dysfunction. Abnormalities in innervation can be seen in cranio-cerebral and cervical diseases, as well as lumbar diseases, which can lead to dysfunction in innervation, limiting the function of the lower limbs and resulting in inability to walk. Problems with muscle strength in the lower extremities can also be seen in neurological and muscular problems, such as nerve abnormalities that can lead to, and muscular disorders that can have corresponding symptoms. Some patients do not walk for a long time, resulting in muscle atrophy and muscle strength deficiency, which can also produce corresponding symptoms. Abnormalities in the bones and joints, including fractures and dislocations, as well as tumors of the bones and infections of the bones, can lead to the inability to walk.
