Impairment of the ability to perform smoothly coordinated voluntary movements. This condition may affect the limbs, trunk, eyes, pharnyx, larnyx, and other structures. Ataxia may result from impaired sensory or motor function. Sensory ataxia may result from posterior column injury or PERIPHERAL NERVE DISEASES. Motor ataxia may be associated with CEREBELLAR DISEASES; CEREBRAL CORTEX diseases; THALAMIC DISEASES; BASAL GANGLIA DISEASES; injury to the RED NUCLEUS; and other conditions.

Disorder, irregularity. Hippocrates employs the word in its most extensive acceptation. Galen applies it, especially, to irregularity of pulse; and Sydenham speaks of Ataxia Spirituum for disorder of the nervous system. Ataxia, now, usually means the state of disorder that characterizes nervous fevers, and the nervous condition.
