Cervical spondylosis can cause lower limb weakness, which can be treated by general therapy, physical therapy, medication or surgery. 1. General treatment: cervical spondylosis can cause lower limb weakness by compressing the spinal cord and nerves, so it is necessary to pay attention to rest, reduce the movement of the head, the pillow should not be too high, and pay attention to keep the neck warm. 2. Physical therapy: If the intervertebral space becomes narrow or the intervertebral disc is herniated, cervical traction can be performed to reduce the pressure on the intervertebral disc. Neuromuscular electrical stimulation can also be performed. 3. Drug therapy: you can follow the doctor’s instructions to apply dehydration and swelling drugs, such as sodium heptaphylloside, oral nutritional nerve drugs, such as methylcobalamin dispersible tablets. 4. Surgery: Ineffective conservative treatment or further aggravation of symptoms requires decompression of the laminae and nerve release surgery. Cervical spondylosis caused by lower limb weakness as early as possible to seek medical treatment to clarify the diagnosis and give targeted treatment.
