Page "Ataxia" Paragraph 13

The term sensory ataxia is employed to indicate ataxia due to loss of proprioception, the loss of sensitivity to the positions of joint and body parts.

This is generally caused by dysfunction of the dorsal columns of the spinal cord, because they carry proprioceptive information up to the brain.

In some cases, the cause of sensory ataxia may instead be dysfunction of the various parts of the brain which receive positional information, including the cerebellum, thalamus, and parietal lobes.
