sensory ataxia

Can result from abnormalities anywhere along the afferent pathway from peripheral nerve, dorsal root, dorsal spinal funiculus, or the
sensory projection from the thalamus to the parietal lobe cortex.
 
 

The functional defect results from an impaired perception of the location of the body part combined with relatively preserved strength in
the member. Clinical findings include defective joint position and vibration sense in the leg and sometimes the arms, unstable stance with
Romberg's sign, and a gait of slapping or steppage quality. Some examples of diseases that cause sensory ataxia are shown in the table
below.

                               Polyneuropathy
 
 

                               Diabetes

                               Hypothyroidism

                               Cisplatin

                               Isoniazid

                               Diphtheria
                                                     Myelopathy
 
 

                                               Acute transverse myelitis

                                               Vacuolar myelopathy(AIDS)

                                               Multiple Sclerosis

                                               Vascular Malformations

                                               Tumor or Cord compression
 

There is a lot of others diseases that can cause disorders of gait and equilibrium, such as spastic ataxia, frontal lobe disorders,
hemiparesis and retropulsion. Nevertheless, their anatomical and physiological basis are very distinct, sometimes poorly understood,
and are beyond the scope of this review.
