Whether the lower limb paralysis can be recovered is related to the causes of lower limb paralysis. If acute myelitis causes paralysis of both lower limbs, after anti-inflammatory, dehydration, neurotrophic and other treatments, patients with incomplete paralysis may recover their limb functions after half a year, but it is difficult to fully return to normal. If the lower limb paralysis is caused by acute cerebral infarction, the lower limb paralysis can be partially recovered after acute treatment when the infarction site is in the non-important functional area. If lower limb paralysis is caused by lumbar disc herniation and nerve compression, when the nerve compression is relieved by early lumbar disc surgery, the amplitude and conduction velocity of lower limb electromyography will slowly recover, and lower limb paralysis can be recovered. Therefore, whether the lower limb paralysis can be recovered depends on the causes of lower limb paralysis and the severity of oppression.
