Truncal ataxia (or trunk ataxia) is a wide-based "drunken sailor" gait characterized by uncertain starts and stops, lateral deviations and unequal steps. It is an instability of the trunk and often seen during sitting. [ 2 ]
Ataxia (from Greek α- [a negative prefix] + -τάξις [order] = "lack of order") is a neurological sign consisting of lack of voluntary coordination of muscle movements that can include gait abnormality, speech changes, and abnormalities in eye movements, that indicates dysfunction of parts of the nervous system that coordinate movement, such as the cerebellum.
Dysmetria is often found in individuals with multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), and persons who have had tumors or strokes.Persons who have been diagnosed with autosomal dominant spinocerebellar ataxia (SCAs) also exhibit dysmetria. [4]
Therefore, inability to walk correctly in tandem gait does not prove the presence of ataxia. [citation needed] Profoundly affected tandem gait with no other perceptible deficits is a defining feature of posterior vermal split syndrome. [1] Suspects may also be asked to perform a tandem gait walk during the "walk and turn" part of a field ...
Cerebellar ataxia is a form of ataxia originating in the cerebellum. [1] Non-progressive congenital ataxia (NPCA) is a classical presentation of cerebral ataxias. Cerebellar ataxia can occur as a result of many diseases and may present with symptoms of an inability to coordinate balance, gait, extremity and eye movements. [ 2 ]
The symptoms of vestibulocerebellar syndrome vary among patients but are typically a unique combination of ocular abnormalities including nystagmus, poor or absent smooth pursuit (ability of the eyes to follow a moving object), strabismus (misalignment of the eyes), diplopia (double vision), oscillopsia (the sensation that stationary objects in the visual field are oscillating) and abnormal ...
Gait abnormality is a deviation from normal walking ().Watching a patient walk is an important part of the neurological examination. Normal gait requires that many systems, including strength, sensation and coordination, function in an integrated fashion.
It is a typical symptom of multiple sclerosis, [3] and it constitutes one of the three symptoms of Charcot's neurologic triad. [4] Scanning speech may be accompanied by other symptoms of cerebellar damage, such as gait, truncal and limb ataxia, intention tremor, inaccuracies in rapidly repeated movements and sudden, abrupt nausea and vomiting ...
