Depending on the cause of the lower limb paralysis, the prognosis is different. If the lower limb paralysis is caused by cerebrovascular disease, through rehabilitation training and medication, the lower limb paralysis will recover as the condition gets better. If the spinal cord injury causes lower limb paralysis, it also depends on the severity of the spinal cord injury. If the severity of the spinal cord injury is mild, it can be recovered after training. If the paralysis of the lower limbs is caused by peripheral nerve injury, the patient will recover faster if the nerve injury is mild. If the nerve injury is more severe, the recovery probability will be lower. Therefore, patients with lower limb paralysis have the hope to recover through rehabilitation training, but the prognosis should be determined according to the degree of nerve damage.
