Corticospinal tract tests
WebPosterior cord syndrome can be diagnosed with clinical tests to assess neurological function. Sensory problems can be assessed by asking an individual to identify different sensations (e.g. temperature, pain, vibration) while touching the skin with specific tools (e.g. dull needle, tuning fork, cotton swabs, etc.). WebLet me write that out. Cortico, cortico which means it starts in the cerebral cortex, and then spinal, which means that it ends in the spinal cord. So it's going from cerebral cortex to spinal cord, so we call it the corticospinal tract. And a tract is a collection of axons traveling together through the central nervous system.
