Pyramidal Pattern Of Weakness. Cord compression classically causes a pyramidal pattern of weakness increased tone in both legs bilateral weakness in flexors brisk reflexes and upgoing plantars Cauda equina will typically cause lower motor neurone weakness flaccid tone in both legs bilateral weakness reduces or absent reflexes and absent plantars. Whether lesions engaging the cortico-spinal pathways cause a selective pyramidal pattern of weakness was directly addressed in both upper and.

Probably accounts for the pyramidal weakness pattern. An upper motor neuron lesion also known as pyramidal insufficiency Is an injury or abnormality that occurs in the neural pathway above the anterior horn cell of the spinal cord or motor nuclei of the cranial nervesConversely a lower motor neuron lesion affects nerve fibers traveling from the anterior horn of the spinal cord or the cranial motor nuclei to the relevant muscles.
