Abstract
|
|
|
Monoplegia is the paralysis of either the upper or lower limb. Monoplegia is commonly caused by an injury to the cerebral cortex; it is rarely caused by an injury to the internal capsule, brain stem, or spinal cord. Most cerebral cortex is derived from the occlusion of a brain cortex blood vessel due to thrombus or embolus.
According to motor homunculus, lower limb monoplegia occurs from limited damage to the most upper part of the primary motor area(Brodmann’s area 4, located in precentral gyrus). Clinically, lower limb monoplegia due to brain cortical infarction is commonly misunderstood as monoplegia due to spinal injury because the lesion is situated at the most upper part of precentral gyrus. We had many difficulties in finding lesion on brain CT, but we diagnosed two patients correctly by using an MRI, who have lower limb monoplegia due to brain cortical infarction oriental treatment.
