Ataxia describes uncoordinated movement and may be present in almost any area of the body. Typically it affects gait and balance most prominently, but it can also cause disability from clumsiness of limb movements and speech impairment. It can be highly variable and is usually secondary to cerebellar dysfunction. The ataxia protocol includes evaluation of speech, eye movements, movements of the extremities, and tandem gait, in addition to some measures assessing parkinsonism (which is often also present with adult neurodegenerative disorders). In addition, all components of the Scale for the Assessment and Rating of Ataxia (SARA) are illustrated in the video examples, including the finger chase.
