Lesion of the dorsal column of the spinal cord: You must be logged in to post a comment.
It leads to lesion of Gracil & Cuneate tracts of both sides. This lead to:
1- Loss of fine touch (tactile localization, tactile discrimination, steriognosis and texture of material).
2- Loss of vibration sense.
3- Loss of proprioceptive sensation (sense of position, movement, deep pressure, muscle stretch and tension), this leads to:
o “Sensory ataxia” which means disturbance and incoordination of voluntary movements. The proprioceptive sensations are needed by the cerebellum to coordinate the movements.
