Definition

Noun: - A form of abasia (inability to walk) specifically caused by ataxia (lack of muscle coordination) in the legs. The primary impairment is not weakness or paralysis, but a severe incoordination of leg movements that makes walking impossible.

Usage

• This is a highly specialized medical term used in clinical neurology to describe a specific symptom. It is not used in everyday conversation.
• It is typically used in patient assessments, medical records, and academic literature to precisely categorize the nature of a walking disorder.

Examples

• The neurological examination revealed atactic abasia, confirming that the patient's inability to walk stemmed from cerebellar dysfunction rather than motor weakness.
• A key differential diagnosis for gait disturbance is distinguishing between paralytic abasia and atactic abasia.

Advanced Usage

• The term is often used in a differential diagnostic context to contrast with other types of abasia, such as (due to paralysis) or (due to muscle spasticity).

Variants and Related Words

• Ataxia (n): The broader neurological condition characterized by lack of voluntary coordination of muscle movements, which is the cause of atactic abasia.
• Abasia (n): The general term for the inability to walk due to impaired motor coordination.

Synonyms

• Ataxic abasia: A fully synonymous term.
• Abasia atactica: A synonymous term using a different word order, common in medical nomenclature.

Notes on Meaning

• The term is a compound noun where "atactic" (derived from ataxia) modifies "abasia" to specify the cause. It refers strictly to the of walking inability resulting from leg ataxia.

Noun

1. abasia due to ataxia of the legs
