Ataxia is manifested as an abnormality of stance and gait. Vestibular paresis also plays a role in ataxia in the early stages of disease. The following characteristics are demonstrated by the patient:

  • Mildest form evident on tandem walking only

  • Wide-based stance

  • Slow and uncertain, short-stepped gait

  • In the most severe form, inability to walk without support

  • Abnormal results on caloric testing (indicates vestibular paresis)
