Cerebellar Ataxic Gait:
Caused by disease process in the cerebellum or cerebellar connections affecting co-ordination, but no weakness; staggering broad based gait with some swaying or lurching – like a “drunken sailor”; inability to walk in straight line; gait is irregular, reeling; slapping foot is characteristic; stride length is shorter; occur with eyes closed or open.
If deficit is mild, may only notice symptoms on occasional steps or stagger when turning. Ataxia can be exaggerated by attempting to tandem walk in a straight line commonly loose balance.
eg alcohol intoxication/chronic alcoholism, multiple sclerosis, stroke, congenital (eg Chiari malformation), hypothyroidism, repeated head injury (‘punch drunk’), brain tumour
Archicerebellar syndrome (flocculonodular lobe) – ataxic gait, vertigo, nystagmus
Paleocerebellar syndrome (vermis and anterior lobe) – ataxic gait, trunk ataxia, lower limb incoordination
Neocerebellar syndrome (cerebellar hemispheres) – ataxic gait, hypotonia, tremor, nystagmus
