Sensory separation
If a disease damages the posterior cord of the back of the spinal cord, making deep sensation unable to conduct upwards, then the position of the limb is not felt, and it is not clear whether it is flexion or extension. Because he lost his understanding of his limbs, he acted awkwardly, walking and rocking. It can be seen that the sensory separation phenomenon is very meaningful for the diagnosis of neurological diseases. Doctors determine what is sick based on the distribution of various sensory disorders. This is called local diagnosis.
