Walking weakness is a manifestation of weakness and easy fatigue in both lower extremities, which can be caused by a variety of diseases, such as spinal cord cervical spondylosis and thoracic spinal stenosis, etc., because of poor innervation of the lower extremities due to compression of the spinal cord in the cervical or thoracic segments. Cervical spondylosis and lesions of the upper thoracic spine manifest as weakness and increased muscle tone in the lower extremities, and patients show weakness and instability in walking, while spinal cord compression in the lower thoracic spine manifests as reduced muscle tone in the lower extremities, with simple weakness as the main manifestation. In addition to the above diseases, neurological lesions in the brain can also cause weakness in the lower extremities, such as Parkinson’s disease, in which patients have tremor and unsteadiness in the lower extremities in addition to weakness in the lower extremities.
