Walking in tandem magnifies the unsteadiness. However, the results are not definitive, because many disorders or problems can cause unsteady gait (such as vision difficulties, problems with the motor neurons, associative cortex or weakness of the lower limbs due to non-neurological causes). Therefore, inability to walk correctly in tandem gait ...
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.
Gait abnormality is also common in persons with nervous system problems such as cauda equina syndrome, multiple sclerosis, Parkinson's disease (with characteristic Parkinsonian gait), Alzheimer's disease, vitamin B 12 deficiency, myasthenia gravis, normal pressure hydrocephalus, and Charcot–Marie–Tooth disease. Research has shown that ...
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]
As a result of this gait impairment, falling is a concern in patients with ataxia. [3] Truncal ataxia affects the muscles closer to the body such as the trunk, shoulder girdle and hip girdle. It is involved in gait stability. [3] Truncal ataxia is different from appendicular ataxia. Appendicular ataxia affects the movements of the arms and legs.
This wide variation illustrates the difficulty of assessing intelligence in autistic individuals. [48] For example, a 2001 British study of 26 autistic children found only about 30% with intelligence in the normal range ( IQ above 70), 50% with a mild to moderate intellectual disability, and about 20% with a severe to profound intellectual ...
The following symptoms or problems are either common or important features of A–T: [citation needed] Ataxia (difficulty with control of movement) that is apparent early but worsens in school to pre-teen years; Oculomotor apraxia (difficulty with coordination of head and eye movement when shifting gaze from one place to the next) Involuntary ...
The test evaluates the ability to stand with one or both legs from stools of heights 10, 20, 30 and 40 cm. [1] The difficulty level increases in order of decreasing stool height and when using one leg instead of two. The test is usually performed in increasing order of difficulty starting from standing up using both legs from a 40 cm high stool.
