Cerebellar ataxia

Malfunction of the cerebellum itself, its input or its outflow results in a characteristic ataxia:

• broad-based clumsy gait
• difficulty walking heel-to-toe
• difficulty standing on one leg
• difficulty in the heel-shin-knee test
• intention tremor and uncoordination in the finger-nose test

Nystagmus, dysarthria and hypotonia are also characteristic of cerebellar disease.
