Which gait is associated with cerebellar dysfunction and presents with a wide base and variable foot placement?

• A. Ataxic gait
• B. Crouched gait
• C. Parkinsonian gait
• D. Hemiplegic gait

Answer: (A)

Gait disturbances from cerebellar dysfunction reflect trouble coordinating movement and maintaining balance. In an ataxic gait, the body tries to compensate by widening the base of support, which helps maintain stability. Steps become irregular and foot placement varies because the cerebellum can’t finely control limb direction and distance (dysmetria). You may also see other signs of cerebellar involvement like intention tremor or past-pointing as movement accuracy declines. This pattern is distinct from crouched gait, which involves a crouched, flexed posture often due to musculoskeletal or cerebral palsy conditions; Parkinsonian gait features a narrow, shuffling walk with reduced arm swing; and hemiplegic gait shows one-sided weakness with foot drop and circumduction.
